Componants of a Cell
| Question | Answer |
|---|---|
| Cell Wall | Only in a plant cell. Protects cell and gives it stability. Componants are polysaccharides and cellulose. |
| Central Vacoule | Only in a plant cell. Place for storage and waste. |
| Chloroplast | Only in a plant cell. Where photosynthesis occurs. Traps energy from sunlight to produce glucose. |
| Cytoplasm | Liquid inside cell. |
| Cytoskeleton | Series of intercellular proteins that help a cell with shape, structural stability and movement of organelles and vesicles (that also transport substances) around the cell. |
| Microtubules | Part of the Cytoskeleton. Made of tubulin, larger than Microfilaments. |
| Microfilaments | Part of the Cytoskeleton. Thinner than Microtules. Made of actin subunits. |
| Microfilaments | Sacs that store and transport substances |
| Endoplasmic Reticulum (ER) | series of membranes; begins at the nucleus and extends throughout the cell |
| Golgi Apparatus | Modifies proteins and lipids. Sorts and packages them inside vesicles for shipment to specific locations within a cell |
| Mitochondria | Power plant of the cell. Where the cells ATP (energy)is made from glucose, amino acids and lipids |
| Nucleus | Contains DNA. Surrounded by 2 phospholipid bilayers. |
| Nuclear Pores | Selectivly allows substances to cross the membrane |
| Nucleoplasm | Fluid within the cell's nucleus |
| Nucleolous | where RNA and proteins are made into ribosomes |
| Rough Endoplasmic Reticulum (RER) | Contains Ribosomes |
| Smooth Endoplasmic Reticulum (SER) | Does not contain Ribosomes |
