Biology Chapter 12 The Cell Essay

Biology 12 - The Cell Part A: In ONE sentence, in the space provided, describe the function of the following organelles. Use point form. Use your own words. Paraphrase and condense the textbook definitions. DO NOT copy any definition or part of a definition. In the box to the left of each definition, make a sketch of the organelle.
|SEE NOTES |1. cell membrane: control what goes in and out of cell, forms barrier with outside environment |
| |2. cell wall: structural support in plant cells. |
| |3. centriole: in animals, function in cell division
chloroplast: in plants, contain photosynthetic pigments that turn light, CO2 and H2O into glucose |
| |5. chromosome: packaging of DNA in nucleus. Functions in cell division |
| |6. cilia: on outside of cell, move materials past cells (e.g. in bronchi and kidney tubules) or used in locomotion. |
| |7. cytoskeleton: internal framework of m.t. and m.f. that move substances in cell and anchor organelles. |
| |8. flagella: used for locomotion in sperm cells and some single celled organisms |
| |9. Golgi body: for packaging, modification, secretion of substances for export inside and outside the cell.
Place these terms in the appropriate column below: centrioles, cell membrane only, cell membrane and cell wall, large central vacuole, small vacuoles only, mitochondria only, mitochondria and chloroplasts, lysosomes, plastids.
