Eukaryotic plant and animal cells each have distinguishing characteristics. For example, plant cells have cell walls, while anim
al cells do not. Which statement BEST elaborates on the reason for this difference? A) Cell walls help plants make their own food by converting light energy. Animals do not make their own food.
B) Animal cells use oxygen, and it cannot pass through cell walls. Plant cells do not need oxygen to pass through.
C) Animal cells produce waste, and a wall would prevent it from leaving the cell. Plant cells do not produce waste.
D) Cell walls of plant cells give plants their rigid shapes, while lack of cell walls allows for mobility in animals.

D) Cell walls of plant cells give plants their rigid shapes, while lack of cell walls allows for mobility in animals.
Explanation:
The cell wall of plant cells is external to the plasma membrane and is composed mainly of cellulose, hemicellulose and pectin. Cellulose, which is formed exclusively by glucose molecule bonds, is the main component of cell walls and is responsible for ensuring its architecture. Cell wall provides stiffness and structural support to the plant cell.
Animal cells do not have a cell wall, so they do not have this rigidity and are malleable in different shapes and sizes, allowing the mobility of the organisms that have it.
