Step 1: Understanding the Concept:
This question requires matching terms from plant biology and tissue culture with their correct definition, example, or associated enzyme.
Step 2: Detailed Explanation:
A. Auxin: This is a class of plant hormones. The principal and most abundant natural auxin is III. Indole-3-Acetic Acid (IAA).
B. Protoplast: To create a protoplast (a plant cell without a wall), enzymes are used to digest the wall components. IV. Pectinase is an enzyme that digests pectin, the substance that glues cells together, and is a key component of the enzyme mixture used for protoplast isolation.
C. Callus: This is, by definition, an I. undifferentiated mass of cell that grows in tissue culture.
D. Cytokinin: This is another class of plant hormones. A well-known synthetic cytokinin is Kinetin, whose chemical name is II. 6-Furfuryl amino purine.
Step 3: Final Answer:
The correct matches are A-III, B-IV, C-I, and D-II.
