Rectangular shape of plant cells in due to:
Correct answer: A. Cell wall
- A. Cell wall
- B. Cell membrane
- C. Vacuole
- D. Cytoskeleton
Explanation
The correct answer is Cell wall. The cell wall is a rigid structure that surrounds the cell membrane in plant cells, providing them with shape and support. This rigidity is what gives plant cells their characteristic rectangular shape. In contrast, the cell membrane is flexible and does not enforce a specific shape on the cell. The vacuole, while important for maintaining turgor pressure, does not define the overall shape of the cell. Lastly, the cytoskeleton offers internal structure but is not responsible for the cell's external shape.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
