Answer:
20. c. cell membrane
The cell part that allows only certain substances to diffuse into and out of the cell is called the semi permeable membrane. This allows good substances to enter the cell.
21. a. Vacuole
A vacuole is the storage area of the cell. Vacuoles store water, food, and waste. The endoplasmic reticulum (ER) is a series of tunnels throughout the cytoplasm.
22. b. Lysosomes
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. ... They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
24. a. Cell wall
The organelles found only in plant cells include- chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.
25. a. nucleus
The nucleus is a large, round/oval structure usually located near the center of the cell. It is the control center for all the activities of the cell.
