Question | Answer |
cell membrane | controls the movement into and out of the cell |
cytoplasm | fluid that includes everything inside cell membrane and outside nucleus |
rough ER | membrane network with ribosomes attached location where proteins are made and transported to other parts of cell |
nucleus | organelle that holds the molecule that carries the code for making a protein |
ribosomes | site of protein synthesis |
Golgi apparatus | flattened disks used for repackaging of proteins lipids and carbs for export |
mitochondria | changes food energy into ATP |
lysosomes | contains hydrolytic enzymes involved in the digestion of food within the cell |
centrioles | involved in cell division in animal cells |
vacuole | fluid filled organelles enclosed by a membrane; contains stored food or wastes |
nucleolus | site of the production of ribosomes |
nuclear envelope | controls movement into and out of the nucleus |
cell wall | gives the cell it's shape and provides protection; not found in animal cells |
cilia | hairlike structures giving the cell the capacity for movement |
flagella | a long hairlike structure used for movement |
cytoskeleton | mesh like network of protein fibers |
chloroplast | site of photosynthesis |
cell plate | during cytokinesis new cell forms on both sides |
chromosomes | rod shaped bodies of Dna that carry genetic information |
central vacuole | holds water and supports plant cell from inside out |
why are small cells survive better than large cells? | has more surface area but has a small volume so it can absorb more nutrients |
what trick can a large cell do to maintain a large surface area volume ratio? | they have a folded membrane with arm like extensions and increases the Surface area |
what do all eukaryote cells have that enable them to be efficient in exchange of materials inside the cell? | have many folded membrane organelles that increase the surface area for exchange |
cell theory | all living things are made up of cells. cells are basic structure and function in living things. all cells come from other things |
schleiden | discovered plant |
schwann | discovered animal |
virchow | concluded all cells come from other cells |
hooke | first to use word cell |
