| Question | Answer |
|---|---|
| what are cells | cells are basic units/building blocks that make up the structure of an organism |
| whats an organelle | a cell component that performs specific functions for the cell. |
| examples of cell organelles | 1) cell membrane 2)Nucleus 3)Mitochondria |
| what does a ultrastructure of a cell membrane look like | Phospholipids,Phosphates,lipids and Proteins |
| role of cell membrane | controls entry and exit of molecules in the cell and gives cell shape |
| selective permeable | allows some material pass in and some material not |
| is nucleus surrounded by a double membrane and does it have nuclear pores to allow movement in or out | yes |
| whats the nucleus called | the control centre |
| what do genes control | features of organism e.g eyes,height,fingers |

| functions of smooth Er | produces proteins |
| functions of rough Er | produces and transports new proteins and membranes |
| what happens to molecules that arrive at the golgi apparatus | they are altered stored and transported to their final destination through vesicles, |
| whats a unicellular organism | one cell big and all its functions are carried out within that one cell |
| whats a multicellular organism | organism that is composed of many cells |
| what are prokaryotic cells | no membrane enclosed organelles e.g bacteria |
