Options
D
Marking Scheme
- 11 mark for selecting the correct option (D)
Hint
Think of the plant hormone whose name is derived from 'cytokinesis', which means cell division.
Analysis & Explanation
Cytokinins are plant hormones that naturally promote cell division, particularly in areas of rapid cell division such as fruits and seeds.
- Auxins (Option B) are synthesized at the shoot tips and help the cells grow longer (cell elongation).
- Gibberellins (Option A), like auxins, help in the growth of the stem.
- Abscisic Acid (Option C) is a growth inhibitor, which causes effects like the wilting of leaves.
Common Mistakes
- 1Students often confuse Auxins with Cytokinins. Auxins promote cell elongation, whereas Cytokinins specifically promote cell division.
Interesting Facts
The term 'cytokinin' is directly related to 'cytokinesis', the physical process of cell division where a single eukaryotic cell divides into two daughter cells.
