Question

using your notes, complete the table by writing the name of the cell part alongside its function. a cell part may be used once, more than once or not at all

function	cell part
2. the sites of protein assembly
3. the clear fluid inside the cell
4. digests excess or worn - out cell parts, food particles and invading viruses or bacteria
5. er with ribosomes
6. produce a usable form of energy for the cell
7. modifies proteins chemically, then repackages them
8. converts harmful free radicals to water
9. makes cholesterol
10. detoxifies cells of drugs
11. the cells bones and muscle
12. makes cell membranes
13. projections of the cell membrane increasing the membrane surface area

Explanation:

1. A membrane - bound, fluid - filled sac holding all parts of a cell is the cell membrane. It acts as a barrier and controls the movement of substances in and out of the cell.
2. The sites of protein assembly are ribosomes. They translate mRNA into proteins.
3. The clear fluid inside the cell is cytoplasm. It contains all organelles and cell parts.
4. The organelle that digests excess or worn - out cell parts, food particles and invading viruses or bacteria is the lysosome. It contains digestive enzymes.
5. ER with ribosomes is rough endoplasmic reticulum. It is involved in protein synthesis and modification.
6. The organelle that produces a usable form of energy for the cell is the mitochondria. It is the powerhouse of the cell.
7. The organelle that modifies proteins chemically, then repackages them is the Golgi apparatus.
8. The organelle that converts harmful free radicals to water is the peroxisome.
9. Cholesterol is made in the smooth endoplasmic reticulum.
10. The organelle that detoxifies cells of drugs is the smooth endoplasmic reticulum.
11. The cell's bones and muscle is the cytoskeleton. It provides structural support and aids in cell movement.
12. The organelle that makes cell membranes is the smooth endoplasmic reticulum.
13. Projections of the cell membrane increasing the membrane surface area are microvilli.
