Question:
The essential hormone for cell division during germination of seeds is
The essential hormone for cell division during germination of seeds is
Show Hint
Gibberellins induce $\alpha$-amylase enzyme synthesis; Cytokinins stimulate active cell division in embryonic axes.
Updated On: Sep 15, 2026
- Abscisic acid
- Gibberelic acid
- Cytokinin
- Ethylene
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Seed germination and seedling establishment require hormonal activation of mitotic cell division in the embryonic radicle and plumule.
Step 2: Detailed Explanation:
Cytokinins (such as zeatin and kinetin) are phytohormones that promote cell division (cytokinesis) and mitotic spindle activation in the embryonic axis of germinating seeds.
While Gibberellic acid (GA) mobilizes aleurone $\alpha$-amylase enzymes to break down endosperm starch into sugars, Cytokinin is the essential hormone directly driving cell division in the meristems.
Step 3: Final Answer:
Thus, the hormone essential for cell division during germination is Cytokinin.
