Science 8 - Cells
Cells
| Term | Definition |
|---|---|
| Capillaries | Tiny blood vessels only one cell thick that connect arteries to veins |
| Tissue | A group of similar cells working together to perform a similar function |
| Organelles | Structures in cells that perform specific functions |
| Cell Membrane | Controllable Gateway (determined what comes in and out of the cell) |
| Cell Wall | Frame for a plant cell |
| Cytoplasm | Fluid in the cell that contains nutrients |
| Nucleus | The brain or command centre of the cell |
| Vacuoles | Storage rooms for cells - stores food and waste |
| Mitochondria | Kidney shape that is the power plant of the cell |
| Chloropalasts | In plant cells only - makes sugar for plants using the light energy of the sun |
| Cell | Individual living unit that makes up all living organisms. |
| Organisms | Made up of two or more cells - multicellular (means more than one) |
| Specialized Cells | Perform specific functions required for life |
| Uni-Cellular | Organism with only one cell |
| Example of a uni-cellular organism | Amoeba, Paramecium |
| Diffusion | Movement of particles from an area where there is more of them to an area where there are fewer of them; High concentration to Low concentration; Liquor or Gas |
| Cell division | All Cells produce by cell division - where the division results in two identical copies of the organism. |
| Red Blood Cells | Carries oxygen to all cells of the body |
| Connective Tissue | Supports and connects different parts of the body |
| Epithelial Tissue | Skin |
| Nervous Tissues | Brain, Spinal Cord, Nerves |
| Muscle tissue | Allows you to move - Heart, Muscles |
| Characteristics of Living Things (6 points) | 1. Made up of cells 2. Need energy 3. Grow and develop 4. Reproduce 5. Respond to their environment 6. Adapt to their environment |
| Golgi Body (or Golgi Complex) | packaging plat that gets things ready to be sent out. Looks like a stack of panacakes. |
| Ribosome | Where proteins are assembled (small round like balls) |
| Endoplasmic Reticulum | Maze of tubes or tunnels - several in each cell |
| Lysosome | Contain enzymes that aid in digestion of nutrients - the stomach of the cell. Looks like rods in animal cells. Not found in plant cells. |
| Name two things found in a plant cell that are not found in an animal cell. | 1. Chloroplast 2. Cell wall |
| Pseudopods | The bulge created by an Amoeba when it moves. These are also used to draw in food for the amoeba to eat. |
| Organs | Group of tissues working together to perform a particular function. |
| Systems | Group of organs that work together to perform a particular function. |
| Osmosis | The diffusion of water through a selectively permeable membrane that moves water from high concentration to low concentration. |
