organelle FUNctions
yay! they're FUN!
| Question | Answer |
|---|---|
| Cell Wall | provide support and protection of the cell. |
| Cell membrane | regulates what enters and leaves the cell. Also provides protection and support |
| Cytoskeleton | a network of protein filaments that helps the cell maintain its shape. Also involved in movement |
| Chloroplasts | organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis. |
| Mitochondria | are organelles that convert the chemical energy stored in food into compounds that are more convenient for the cell to use. |
| Vacuoles | store materials like water, salts, proteins, and carbohydrates. |
| Lysosomes | are small organelles filled with enzymes. Function is to breakdown lipids, carbohydrates and proteins so that they can be used by the rest of the cell. They also break down old organelles. |
| Golgi Apparatus | modify, sort, and package proteins and other materials form the endoplasmic reticulum for storage in the cell or secretion outside the cell. |
| Smooth E.R. | contains collections of enzymes that perform specialized tasks, including the synthesis of membrane lipids, and detoxification of drugs. |
| Rough Endoplasmic Reticulum | synthesis of proteins. Newly made proteins leave the ribosomes and are inserted into the R.E.R., where they are chemically modified. |
| Endoplasmic reticulum | the site where lipid components of the cell membrane are assembled, along with proteins and other materials that are exported from the cell. |
| Ribosomes | are small particles of RNA and protein found throughout the cytoplasm. They produce proteins by following the coded instructions that come from the nucleus. |
| Nucleus | contains nearly all the cell’s DNA and with it the coded instructions for making proteins and other important molecules |
