Cell structure
function of cell parts
| Question | Answer |
|---|---|
| Nucleus | CONTROL CENTER -contains DNA, RNA, and proteins. Separates DNA from the rest of the cell. First step of protein synthesis. |
| Nucleolus | produces ribosomal subunits |
| Ribosome | WORKBENCHES - globular subunits composed of RNA and Protein. Houses protein synthesis |
| Rough Endoplasmic reticulum | ASSEMBLY LINE - studded with ribosomes - produces proteins destined for secretion from the cell |
| Smooth Endoplasmic reticulum | ASSEMBLY LINE - lacks ribosomes - synthesizes lipids and detoxifies drugs and poisons |
| Golgi Apparatus | DISTRIBUTION CENTER (packaging) - packages materials to be secreted. PRODUCES LYSOSOMES |
| Lysosome | CLEANING CREW - contains digestive enzymes. recycles components of food, debris, bacteria, and worn-out organelle |
| Central Vacuole | produces turgor pressure, recycles cell contents, contains pigments. |
| Mitochondria | POWERHOUSE - Contains DNA and ribosomes. releases energy from food by cellular respiration |
| Cytoskeleton | STRUCTURE - protein filaments and tubules. transports organelles within the cell |
| Peroxisome | GARBAGE MAN - disposes of toxins, breaks down fatty acids, eliminates hydrogen peroxide |
| Chloroplast | PHOTOSYNTHESIS CELL - has DNA. uses light energy to form sugars and oxygen |
| Cell Wall | only in plants. Protects the cell |
