1 Table of Contents Chapter: Life's Structure and Classification Section 1: Living Things
2 1- What is an organism? Any living thing is called an organism. Organisms vary in size: 1)one-celled or unicellular organisms that are one cell only 2)many-celled or multicellular organisms made of more than one cell
3 2- What is a cell? A cell is the smallest unit of an organism that carries on the functions of life. *Cells are the building blocks of life.
4 *What are the main differences between living and non-living things?
5 *All living things have similar traits that determine what it means to be alive. Composed of cells Living things grow and develop Can reproduce Maintain internal balance ( homeostasis) Need energy to survive (food) Respond to stimuli from the environment
6 *Living Things Are Organized Unicellular Organisms and Cells are internally organized Cells have internal structures ( organelles) responsible for certain functions that will keep the cell alive Multicellular Organisms are also organized Organisms have internal structures ( cells, tissues, organs and systems) responsible for certain functions that will keep the organism alive.
7 *In a Multicellular organism: Each cell carries on its own life functions but also performs a job for the whole organism. Ex: Muscle cell perform a job for the organism help with the contraction of the muscle and provide the necessary energy for this contraction Also needs to perform basic functions to be alive.
8 *Levels of Organization of a many-celled organism or multicellular organism: Cells tissues- organs organ systems organism
9 Many-Celled Organisms A tissue is a group of similar cells that work together to do one job. Tissues are organized into organs.
10 Many-Celled Organisms An organ is a structure made up of two or more different types of tissues that work together.
11 Many-Celled Organisms A group of organs working together to perform a specific function is an organ system.
12 ** All the functions that organisms perform to survive, are also performed at a cellular level respiration, digestion, elimination of waste materials. All the things an organism can do are possible because of what their cells can do
13 3- How do organisms grow? Growth of organisms is mostly due to an increase in the number of cells.
14 Life Span Is the length of time an organism is expected to live. Humans 80 years Some insects live one day Some pine tress can live 4600 years
15 4- How do living things interact with its surroundings and maintain internal balance? By responding to stimuli ( plural). A stimulus ( singular) is anything that change in the environment that can affect the organism s internal equilibrium.
16 The reaction to a stimulus is a called a response and responding to stimuli is important for the survival of this organism. Ex: Stimulus someone pinches you on your arm unexpectedly Response move the arm away quickly.
17 5- What is Homeostasis? The regulation of an organism's internal, life-maintaining condition despite changes in its environment is called homeostasis. ** Series of mechanisms responsible for maintaining internal balance of an organism. EX: Homeostasis keeps our body temperature constant
18 Temperature drops in the environment is the stimulus What would be the responses???? 1) you feel cold and start shaking shaking produces heat and warms up your body 2) vasoconstriction superficial veins contract, lowering the surface exposed to the outside - decreases heat lost Both responses try to maintain the ideal body temperature, which is part of the body s equilibrium
19 6 - How do organisms obtain E? The energy used by most organisms comes either directly or indirectly from the Sun. *Some are producers *Others will eat the producers to obtain the energy Four ways in which an organism can obtain energy:
20 Organisms that can synthetize their own food producers How do they obtain Energy???? **1)Photosynthesis some organisms use sun s energy, water and carbon dioxide to produce their own food **2)Chemosynthesis process in which organisms produce their own food in the absence of light. The source of energy is a chemical substance.
21 Organisms that can t synthetize their own food consumers How do they obtain Energy? **1) Cellular Respiration- organisms that can t produce their own food will eat the photosynthetic organisms and break this food in the presence of oxygen, producing E and carbon dioxide.
22 Organisms that can t synthetize their own food consumers **2) Fermentation - the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms producing carbon dioxide and energy. **Used by microorganisms when oxygen is not available. The process of fermentation is involved in the making of beer, wine, and liquor, in which sugars are converted to ethyl alcohol.
23 7- Why do Living Things Reproduce? All living things reproduce, to make more of their own kind. *The main goal of any living organism is to reproduce to guarantee the survival of the species
24 8 - What do living things need to survive? 1) a place to live with enough space to grow 2) water needed for many basic cell functions 3) Food give them energy All living organisms need proteins, minerals, vitamins, carbohydrates ( sugars) and fat to survive and organisms take in these materials when they eat.
25 **What differentiates plants from animals? Plants can make their own food and animals can t Plants take in carbon dioxide and release oxygen, animals do the opposite Animals can move and plants can t Unlike animals, plants have little to none ability to sense Plant and animal cells are different
26 Table of Contents Chapter 8: Life's Structure and Classification Section 3: Cell Structure a) The Cell Theory b) Cellular organization
27 a) The Cell Theory:
28 Viewing Cells Microscope allowed us to understand that we are all made of cells Dutch man created the first microscope Antoine van Leeuwenhoek Improved the microscope allowing the development of the cell theory
29 Antoine van Leeuwenhoek s microscope
30 Compound Microscope Compound more than one lens Uses light that shines through the specimen, lens will magnify the image
31 The Cell Theory: describes the existence of cells in organisms There are important events that led to the cell theory
32 I Robert Hooke Looked at cork under a microscope He saw a lot of empty little boxes He named this little boxes cells.
33 Cork or Bark is the external layer of stems and roots of woody plants
34 Cork Cells
35 II- Matthias Schleiden In the 1830s, Matthias Schleiden used a microscope to study plant parts. He concluded that all plants are made of cells.
36 III- Theodor Schwann Observing different animal cells Concluded that all animals also are made up of cells.
37 IV Virchow Several years later, Rudolf Virchow hypothesized that cells divide to form new cells.
38 ** Summary of the cell theory.
39 Looking at Cork Cells
40 Cellular Organization Definition of cell: **Cells are known as the building blocks of life
41 **2nd definition : smallest unit of an organism that can carry on life functions **Like all living organisms, cells must constantly take in nutrients, store, produce, breakdown substances, take in and use energy. These are the basic functions that will maintain any organism and any cell alive.
42 **Cellular Organization is necessary to perform life functions Cells are internally organized and all the functions that organisms perform to survive, are also performed, at a cellular level respiration, digestion, elimination of waste materials.
43 **In our bodies, we have organs and systems that are responsible for these functions. ** The cells have organelles that will perform these functions.
44 ** Cellular Organization Cells have internal compartments, surrounded by membrane, called organelles. Each organelle has a specific function.
45 Prokaryotic x Eukaryotic Cell
46 3 Cell Structure Prokaryotic and Eukaryotic cells. Cells without membrane-bound structures are called prokaryotic cells. ( no nucleus, no organelles, DNA floating in the cytoplasm)
47 3 Cell Structure Cells with membrane-bound structures ( or organelles) are called Eukaryotic cells. The DNA or genetic material is inside the nucleus
48 Cell Wall Cell walls are tough, rigid outer coverings that protect cells and give them shape. Plants, Algae, Fungi, and most Bacteria are enclosed in a cell wall. A plant cell wall is mostly made up of a carbohydrate called cellulose.
49 Cell Membrane The protective layer surrounding every cell is the cell membrane.
50 The functions of the Cell Membrane Protection Regulation of what moves in and out of the cell Allows nutrients to move into the cell Allows waste products to move out of the cell
51 Cytoplasm Gelatin like substance that constantly flows inside the cell membrane. Organelles are in the cytoplasm Most of a cell s life processes occur in the cytoplasm.
52 Ribosomes and the functions of ribosomes Ribosomes are organelles that participate in the synthesis of proteins. They can be free in the cytoplasm or attached to the Rough Endoplasmic Reticulum (RER)
53 The importance of the Nucleus. All cellular activities are directed by the nucleus. Contains the hereditary material or DNA DNA is the chemical that contains the code for cell s structure and activities.
54 Nucleolus A structure called a nucleolus also is found in the nucleus, and is where most ribosomes are made in an eukaryotic cell.
55 Chloroplasts and its importance Chloroplasts are organelles found in plant cells and contain the green pigment chlorophyll. Chlorophyll is a pigment that captures energy from the Sun. Energy from the Sun is needed for Photosynthesis During Photosynthesis sugar molecules are formed inside the chloroplast
56 Mitochondria During photosynthesis sugars are synthetized by the plant. The sugars are stored in the plant. When the plant needs energy, the sugar will be broken down inside the mitochondria. The process of breaking down food releasing energy and oxygen is called cellular respiration and it happens inside the mitochondrion
57 Mitochondria and its importance Mitochondria plural Mitochondrion singular
58 Endoplasmic Reticulum and its importance A series of folded membranes in which materials can be processed and moved to other areas inside the cell.
59 ER: Smooth or Rough (with attached ribosomes)
60 Ribosomes and RER Ribosomes synthetize proteins The proteins are moved to different areas of the cell by the RER rough endoplasmic reticulum
61 Smooth ER processes and transports other cellular substances such as lipids Lipids are substances that store energy.
62 Golgi Bodies The Golgi bodies are stacked, flattened membranes. Sort and package cellular substances into membrane-bound structures called vesicles, for storage or elimination. Unwanted substances are taken to the outside of the cell
63 Vacuoles Cells also have membrane-bound spaces called vacuoles for the temporary storage of materials A vacuole can store water, waste products, food, and other cellular materials.
64 Vacuoles Plant Cells big vacuole occupies almost all the space inside the cell Animal Cells have small vacuoles Why are they different? * Vacuoles in the plant cell are also responsible for the shape of the cell
65 Lysosomes contain digestive chemicals that help break down food molecules, cell waste, and worn-out cell parts. Lysosomes
66 Lysosomes **The lysosome s membrane prevents the digestive chemicals inside from leaking into the cytoplasm and destroying the cell. ** When a cell dies, the lysosome s membrane disintegrates, releasing digestive chemicals that allow the quick breakdown of the cell s contents.
67 Lysosomes are found only in animal cells ** There is debate about the presence of lysosomes in plant cells. Apparently, some vacuoles in plant cells contain some enzymes found in the lysosomes of animal cells, and are responsible for digestion.
68 Page 225 and Figure 13 Animal Cell Animal Cells have: Centrioles involved in the process of cell division Cytoskeleton responsible for shape and movement of some cells See page 243 questions 14 and maybe 15 important additions
69 Differences between Plant and Animal cells Plant cell Cell Wall Yes No Chloroplasts Yes No Animal cell Vacuoles One Big Vacuole Several Small Vacuoles Lysosomes? In discussion Yes Centrioles and Cytoskeleton No Yes Shape Rectangular (ish) Round (ish)
