Comparative cell structure: Plants possess which structural feature that animals lack? Context: Consider the outer covering beyond the plasma membrane in plant cells. Choose the correct structure.

Concept / ApproachPlant cells have a cell wall (primarily cellulose, hemicellulose, pectin) outside the plasma membrane, providing rigidity and shape. Typical animal cells lack a cell wall.

Why others are incorrectMitochondria and lysosomes occur in animals; centrosomes with centrioles are characteristic of many animal cells, not plant cells.

Final AnswerA rigid cell wall is present in plants and absent in animals.
