Question

using your notes, identify the structure being described by each statement below (words can be used more than once):
very large storage sac in plants
digests excess or worn - out cell parts, food particles, and invading viruses or bacteria
the sites of protein synthesis
transports materials within the cell
regulates what can enter or leave the cell (selectively permeable)
organelle that manages or controls cell activities in eukaryotic cells
contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color
small bumps located on portions of the endoplasmic reticulum
provides temporary storage of food, enzymes, and waste products

Explanation:

1. The large storage sac in plants is the vacuole. It stores water, nutrients and waste.
2. Lysosomes digest excess or worn - out cell parts, food particles and invading pathogens.
3. Ribosomes are the sites of protein synthesis.
4. Endoplasmic reticulum transports materials within the cell.
5. The cell membrane is selectively permeable and regulates what enters or leaves the cell.
6. The nucleus manages or controls cell activities in eukaryotic cells.
7. Chloroplasts contain chlorophyll and capture sunlight energy.
8. Ribosomes are the small bumps on the endoplasmic reticulum.
9. Vacuoles can also provide temporary storage of food, enzymes and waste products.

Answer:

1. Vacuole
2. Lysosome
3. Ribosome
4. Endoplasmic reticulum
5. Cell membrane
6. Nucleus
7. Chloroplast
8. Ribosome
9. Vacuole
