NEETBotanyPlant - Growth and Development
Which process does auxin control in plants besides parthenocarpy and weed control?
Options
- APhloem differentiation
- BXylem differentiation
- CSeed dormancy
- DLeaf abscission
Correct answer
B. Xylem differentiation
Step-by-step solution
Auxins also induce parthenocarpy, e.g., in tomatoes. They are widely used as herbicides. 2, 4-D, widely used to kill dicotyledonous weeds, does not affect mature monocotyledonous plants. It is used to prepare weed-free lawns by gardeners. Auxin also controls xylem differentiation and helps in cell division.
