BIOLOGY: CELLS
| Question | Answer |
|---|---|
| CELLULAR ORGANELLE Nucleus | contains genetic material (DNA) and chromosomes |
| CELLULAR ORGANELLE Mitochondria | respiration occurs here; makes energy |
| CELLULAR ORGANELLE Cell membrane | the “skin” of the cell; it encloses the entire cell and food/wastes pass through it |
| CELLULAR ORGANELLE Flagella | is like a long tail used for movement (cilia are little hairs that could also be used for movement) |
| CELLULAR ORGANELLE Chloroplasts | where plant cells use chlorophyll to do photosynthesis. Plant cells contain a cell wall and chloroplasts. Animal cells do not. |
| CELLULAR PROCESSESphotosynthesis | process in which a plant (or other organism) uses light to convert carbon dioxide and water into food/energy |
| CELLULAR PROCESSEScellular respiration | process that releases energy by using oxygen to break down sugar (glucose) and other food molecules into food/energy |
| CELLS | prokaryotes = simple cells that do not have a nucleus; example: bacteria eukaryotes = complex cells that have a nucleus; includes plants, animals, humans, protists and fungi |
