Cell Structures
| Question | Answer |
|---|---|
| cytoplasm | Fluid inside the cell |
| Cell membrane/ plasma membrane | controls what enters and leaves the cell, thus controls homeostasis |
| cell wall | rigid, structure, surrounding the cell membrane; gives extra support & protection |
| Cytoskeleton | cell support, movement, and communication |
| nucleus | stores genetic material(DNA); control center |
| nucleolus | organelle inside the nucleus; makes ribosomes |
| centrioles | pull chromosomes apart during cell division. |
| rough ER (endoplasmic reticulum) | network of tubes with ribosomes; connected to the nucleus; package and transport proteins made by the ribosomes on them |
| smooth ER (endoplasmic reticulum | detoxifies the cell, makes lipids |
| golgi apparatus | modifies, sorts, packages substances made by the cell |
| vesicle | transports substances throughout the cell |
| vacuoles | store water, waste, nutrients, and other chemicals; |
| chloroplast | contains green pigment/chlorophyll; responsible for photosynthesis |
| mitochondria | powerhouse of the cell; makes ATP energy |
| cilia/cilium | short, hair-like, used for movement |
| flagella/flagellum | long, whip-like, used for movement |
| central vacuole | 1 large, center of plant cell; stores food, water, waste |
| ribosomes | make proteins |
| lysosome | contains digestive enzymes; breaks down unwanted cell parts and wastes |
| peroxisome | detoxifies the cell of toxic substances |
| What do plant cells have that animal cells do not? | chloroplast, cell wall, large central vacuole |
| What do animal cells have that plant cells do not? | lysosomes, centrioles, many small vacuoles |
| Give examples of Eukaryotic cells. | plant, animal, fungus, protist |
| Give an example of a Prokaryotic cell. | bacteria |
