Monday Pick up a warm up paper when you walk in and begin working immediately.

Levels of Organization Remember, cells are made of organelles. An organelle is basically a tiny organ that is found within the cell. Each organelle performs a specific function for the cell. (We ll learn about these later.) Elements Molecules Organelles Cells

Membrane-Bound What s That? Organelles can be membrane-bound, or not. Membrane-bound means the organelle is surrounded by a membrane.

Nucleus The nucleus is responsible for storing DNA. There are MANY more organelles, but we will cover the rest of the organelles and their functions later.

How Many Cells are in the Body? There are approximately 37 Trillion cells in your body.

2 Types of Cells There are only 2 types of cells in the world. A cell can either be a prokaryote or a eukaryote. Bacteria Prokaryotes Animal cell Plant cell Eukaryotes Prokaryotes are always going to be bacteria! ALWAYS! Eukaryotes are every cell type besides bacteria cells. Every single prokaryotic cell is a bacteria. The most common types are plant and animal cells, but there are others like a fungus.

The Difference What makes them different are the presence or absence of Membrane Bound Organelles (MBO for short). Membrane bound organelles are organelles that have their own Membrane (boundary) to separate their inside contents from the rest of the cell.

Examples Prokaryotes Bacteria Eukaryotes Animal Smaller vacuole Fungi Plant Chloroplast Larger vacuole Protists

Prokaryotic Cells Definition: simple, single celled organisms that lack (do not have) a true nucleus. They can exist in a large range of environments, such as: hot, harsh temperatures without oxygen around extreme salt or methane some can make their own food

Prokaryotic Cells Examples include: All Bacteria For example Escherichia coli (Ecoli) bacterium Pro. rhymes with NO, meaning NO Nucleus or membrane-bound organelles.

Flip to the Back Prokaryotes Organelles: Nucleoid: DNA is free floating in the cytoplasm

Definition: Cells that contain: Eukaryotic Cells TRUE nucleus (w/ DNA) membrane-bound organelles Considered to be more complex because they are larger and have many organelles in an organized manner.

Eukaryotic Cells Examples: Animals Plants Fungi Protists Eu. ryhmes with DO, meaning they DO have Nucleus and membrane-bound organelles.

Eukaryotic Cell Animal Cell Plant Cell

Flip to the Back Eukaryotes Organelles: (Membrane bound organelles only found in Eukaryotes) Nuclear Envelope: DNA inside, holds genetic material that controls cells functions Mitochondria: makes the energy for the cell(atp) by doing cellular respiration (Power House)

Flip to the Back Eukaryotes Organelles: (Membrane bound organelles only found in Eukaryotes) Chloroplast: Found in plant cells, where they perform photosynthesis to produce glucose.

Organelles: Cell Membrane: (Plasma membrane) controls what enters and leaves the cell Cytoplasm: gel like substance that holds organelles in place Common to Both

Organelles: Ribosome: Protein Synthesis takes place in the ribosomes. Common to Both DNA: can be free floating or Housed inside a nucleus

Cell Transport Cell Membrane Also known as the Plasma Membrane and Phospholipid Bilayer Job: Separates the inside of the cell from the outside and regulate movement of molecules in & out of the cell.

Inside vs. Outside Inside Cytoplasm Outside Inside

Phospholipids Bilayer Fearing Loving

Protein 1. Draw in the Channel in some of the proteins 2. Label Channel

Carbohydrate Chain 1.Draw in two carbohydrate chains 2.Label

Label the Biomolecules Write somewhat small near the Nucleus: Nucleic Acids Stores genetic Material (DNA/RNA) Monomer: Nucleotides polymer: DNA or RNA

Label the Biomolecules Label near the Carbohydrate Chain: Carbohydrate (Polysaccharide) Quick Energy Cell identification Monomer: Monosaccharides polymer: polysaccharide or disaccharide

Label the Biomolecules Label near the Proteins: Proteins Structural support transport substance in and out of the cell Enzymes- speed up chemical reaction monomer: Amino Acids polymer: polypeptide chain

Label the Biomolecules Label near the Phospholipid: Lipid makes up the cell membrane Long term energy Monomer: glycerol and fatty acids

The Cell Membrane s key function is to regulate particles moving in and out of a cell. Small particles may move through the phospholipid bilayer, while other particles must pass through a transport protein. Cell Membrane Identify the following: - Phospholipids - Proteins - Hydrophobic tails - Hydrophilic heads

Selectively Permeable/Semi- Permeable Semi Permeable: Allows some substances through the membrane but not others.

Concentration Gradient The difference between the concentration of solutes in solutions. Natural flow is from high to low. (with the concentration gradient)

Cell Transport A process that helps cells maintain homeostasis. It involves the movement of molecules across the cell membrane. Two types: Passive and Active

Vocabulary Solution: a mixture of one or more substances Solute: what is being dissolved Ions, sugar, salts, proteins, other substances Solvent: what is doing the dissolving Water is the universal solvent Copyright McGraw-Hill Education Cellular Transport

Passive Transport Process by which molecules move with their concentration gradient. Molecules move from high to low concentrations. Requires NO ENERGY.

Simple Diffusion An example of passive transport in which small molecules move from areas of high concentration to areas of low concentration until homeostasis is reached.

Diffusion in a Cell -some substances can diffuse directly through the plasma membrane Copyright McGraw-Hill Education Cellular Transport

Facilitated Diffusion Diffusion of molecules from high to low concentration with the assistance (help) of a transport protein. Occurs when the molecule is too large or polar.

Facilitated Diffusion Movement of materials across the plasma membrane using proteins Channel Proteins Channel proteins open and close to allow substances to diffuse through the plasma membrane Copyright McGraw-Hill Education Cellular Transport

Osmosis Type of passive transport Process in which are WATER molecules moving across a permeable membrane. H 2 Osmosis

How Does Osmosis Work? WATER always moves from the side with more water to the side with less water. In other words, water will always move to the side that has a higher concentration of solutes. Which side of the tube will the water rise?

Hypertonic Solution A solution that has LESS WATER than the cell. Will this cell swell, shrink, or stay the same?

Hypotonic Solution A solution that has MORE WATER than the cell. Will this cell to shrink, swell, or stay the same?

Isotonic Solution A solution that has the SAME AMOUNT of water as the cell. Will this cell to shrink, swell, or stay the same?

Recap PASSIVE TRANSPORT 3 Characteristics HIGH TO LOW NO ENERGY WITH concentration gradient 3 Types Simple Diffusion: Movement of particles WITHOUT the assistance of a PROTEIN Facilitated Diffusion: Must be assisted by a PROTEIN Osmosis: Movement of WATER molecules ONLY

Active Transport Process by which particles move AGAINST their concentration gradient Movement from LOW TO HIGH concentrations Requires ENERGY

ANALOGY: Passive vs. Active Transport PASSIVE TRANSPORT: * NO ENERGY required * HIGH TO LOW * WITH con. gradient Examples: Diffusion Facilitated Diffusion Osmosis ACTIVE TRANSPORT: * ENERGY required * LOW TO HIGH * AGAINST con. gradient Examples: Endocytosis Exocytosis Sodium-Potassium pump

Passive Transport Move from High to Low concentration. No Energy needed. Active Transport Move from Low to High concentration. Energy needed. With/Down concentration gradient. Against/Up concentration gradient.

Passive vs. Active Transport

Active Transport 2 types of active transport: Exocytosis Endocytosis Can you figure out what each terms means?

Endocytosis Cell membrane folds inwards moving/engulfing substances INTO the cell Phagocytosis: the cell membrane surrounds the particle and pinches off to form an intracellular vacuole Pinocytosis: the cell membrane surrounds a small volume of fluid and pinches off, forming a vesicle Receptor-mediated endocytosis: uptake of substances by the cell is targeted to a single type of substance that binds at the receptor on the external cell membrane

Exocytosis Exocytosis: a vesicle migrates to the cell membrane, binds, and releases its contents moving substances OUT of the cell.
