What part helps plant cells keep their shape?

• A. Nucleus
• B. Cell Wall
• C. Cytoplasm
• D. Chloroplast

Answer: (B)

Plants keep their shape mainly because of the cell wall, a sturdy layer outside the cell membrane. Made largely of cellulose, it provides rigidity and support so the cell holds its form, even as water moves in and out. The cell wall works with turgor pressure from the central vacuole to keep the plant firm. The nucleus is the control center with the cell’s DNA, the cytoplasm is the jelly-like space where many reactions occur, and chloroplasts capture light for photosynthesis. These parts do not primarily give the cell its shape.
