1 Year 7 - Cells Summary Notes Life Processes All living things do all seven of the life processes. Things that are not living may do some but do not do all seven of the life processes. These are: Movement Respiration Sensitivity Growth Reproduction Excretion Nutrition Viruses are difficult to classify as living or non-living. They are not cellular and do not do all of the seven processes above. They can only reproduce when they are inside a cell, but can survive for years outside of a cell, showing no signs of life until they are inside a cell again. Cells An organism is any living thing. All organisms are made up of cells. Cells are the building blocks that make up living things. Organisms can be unicellular (consist of only one cell) or multicellular (contains many cells) Cells are microscopic. Microscopic means very small to see. Therefore cells need to be looked at them under a microscope. Types of microscope Light microscopes combines two lenses to magnify up to a thousand times. Electron microscopes use a beam of electrons instead of light to magnify by a much greater amount.
2 Magnification Magnification means get bigger. The total magnification of a light microscope is the magnification of the ocular (eyepiece) lens times the magnification of the objective lens. Magnification can be calculated by using the formula: mmmmmmmmmmmmmmmmmmmmmmmmmm = iiiiiiiiii aaaaaaaaaaaa Using a microscope The specimen is put on a microscope slide and covered with a cover slip. This can be done with a mounted needle. Objects are often difficult to view under the light microscope because of lack of contrast between the object and the surroundings. To increase the contrast staining is used. Staining is used for the following reasons Enables differentiation between different components in the cell. Can cause transparent and translucent structures within the cell to become apparent. Allows the composition of various parts of the cell to be determined. The process of staining may kill or change the cell in some way. Structure of cells Cells are small liquid filled sacs. They are 3 dimensional. They contain many different structures to help them grow, divide and perform lots of different functions. The general structure is shown below.
3 Part of cell Function (what it does) Plant, animal or both Cell wall Support and shape. Plant Cell membrane Controls what goes in and out of cell. Both Nucleus Cytoplasm Vacuole Chloroplast Controls all the activities of the cell. Contains all the genetic information. Jelly like substance where chemical reactions take place. Many functions including storage of waste and water. Used in photosynthesis (the process where plants make their own food). Both Both Large in plants, small or missing in animals Some plant cells. Bacterial cells Bacteria are simpler than plants or animals. They are always unicellular (contain only one cell). Bacterial cells have no nucleus, vacuoles or membrane bound organelles. While bacteria and plants both have a cell wall the cell walls are a very different structure. Many bacterial cells have a flagellum to help them move.
4 Cell differentiation In multicellular organisms, cells are specialised to perform particular jobs. Cell Diagram Function Adaptations Red blood cells Carry oxygen around body. No nucleus (able to carry more oxygen), biconcave shape (flexible). Muscle Cells Movement. Able to change length. Ciliated epithelium Wafts mucus, dirt and bacteria up to back of throat. Cilia (hair like structures). Nerve Cell Carries electrical signals around body. Can be long, branched. Sperm cell Fertilises an egg cell. The tail helps the sperm move to the egg. The head contains genetic information. Head also has an enzyme to help penetrate the egg cell. Palisade cell Photosynthesis (process where plants make their own food). Contain lots of chloroplasts. Root hair cell Absorbs water and minerals from the soil. Has large surface area and a thin wall. Xylem Transports water up a plant. Hollow. Cells to organisms Clearly organisms are more than collections of cells. The organisation of an organism is: Cell > Tissue > Organ > System > Organism
5 Level of Organisation Definition Example Cell The building block of all living things. Red blood cell Tissue Group of similar cells that work together to perform a particular job Organ A group of different tissues that work together. Heart System Groups of organs that work together. The organs in a system are linked together by tubes or vessels. Cardiac muscle Circulation Organism All the systems work together to form the whole organism. Human There are many different organ systems in the body including: System Organs and tissues include Function Circulation Respiratory Digestive Heart, blood vessels (arteries, veins and capillaries). Trachea (windpipe), lungs, diaphragm. Oesophagus (gullet), stomach, large intestine, small intestines, anus. Transports nutrient and wastes around the body in the blood. Taking in oxygen and removing carbon dioxide. Breaks down food into simple substances. Excretory Kidneys, bladder. Removes waste. Nervous Sense organs, brain, spinal cord, nerves. Sends messages around body. Endocrine (hormone) Endocrine glands including thyroid, Makes and releases hormones. pancreas, ovaries and testes. Muscular Skeletal Reproduction Bones, cartilage, muscles, tendons and ligaments. Uterus, vagina, ovaries, fallopian tube, penis, sperm duct, testes. Support and movement. Producing offspring.
6 Here is the location of some of the organs in humans and plants: Plant Organs Organ Leaf Petals Roots Function Photosynthesis (make food). Attract pollinators. Absorb water and minerals from soil, anchor plant in ground. Skeleton The functions of the skeleton are: 1. Protection 2. Movement 3. Gives shape 4. Makes blood cells Bone is made of: Minerals calcium phosphate is the mineral in the greatest quantity. Calcium phosphate makes the bone strong and difficult to bend. Protein mainly collagen Living cells these build and repair cells. The cells also make bone cells and blood cells.
7 An individual bone has: a strong dense outer layer spongy layer bone marrow where the blood cells are made Joints Joints are where two or more bones meet. Three types: Immovable (fibrous) Cartilaginous (partially moveable) Synovial (freely moveable) Cartilage reduces friction Synovial fluid reduces friction Ligaments join bones Tendons join bone to muscles Muscles There are three types of muscle: Skeletal muscle Smooth muscle Cardiac muscle Muscle cells contain protein fibres that slide past one another, producing a contraction that changes both the length and the shape of the cell. This means that muscles cannot push they can only pull. Skeletal muscles are found in antagonistic pairs. As they can only pull and not push, they need to be in pairs so that a muscle can extend after contracting. The biceps and the triceps are antagonistic muscles. when the biceps muscle pulls or contracts, the forearm moves up when the triceps muscle pulls or contracts, the forearm moves down.
8 Making new cells New cells can only be made from existing cells. New cells need to be made: to replace cells to grow to produce offspring There are two types of cell division: for growth and repair to make sex cells, for reproduction. Steps in making new cells: 1. Growth the cell grows bigger 2. Duplicating the chromosomes (that contain all the genetic information) are copied. The nucleus divides. 3. Division the two nuclei go to opposite ends of the cell. The cells split into two. The male sex cell is sperm in animals and pollen in plants. The female sex cell is the egg or ovum. To form new offspring the male and female sex cell joins together in a process called fertilisation. The reproductive part of a plant is the flower. Pollination is the transfer of pollen from a stamen (which makes the pollen) to a pistil.
