Explanation
Plant vacuoles perform lysosomal functions via hydrolytic enzymes
Steps:
- Lysosomes in animal cells contain hydrolytic enzymes for intracellular digestion.
- Mature plant cells lack true lysosomes but use vacuoles for similar breakdown roles.
- Identify the choice linking hydrolytic enzymes to a plant organelle.
- Option A directly states this for vacuoles, supporting the lysosomal analogy.
Why A is correct:
- Lysosomes are defined by housing hydrolytic enzymes that degrade macromolecules in acidic conditions; plant vacuoles contain these enzymes, fulfilling the same digestive role.
Why the others are wrong:
- B: Describes glycogen breakdown but does not specify an organelle or lysosomal enzymes.
- C: Refers to vesicle formation from Golgi, resembling peroxisomes, not lysosomal digestion.
- D: Mentions general enzyme-containing vesicles from the membrane, unrelated to plant-specific lysosomal functions.
Final answer: A
