The correct answer is radicle.
Key Points
- The first step in the process of plant growth is seed germination.
- The seed germinates when favourable conditions for growth exist in the environment.
- In absence of such favourable conditions, the seeds do not germinate and go into a period of suspended growth or rest.
- Once favourable conditions return, the seeds resume metabolic activities and growth takes place.
- The root system begins its development from the embryonic root also called radicle, which grows out of the seed after the seed has absorbed water.
- This is the primary root of a new plant.
- The tip of the root is covered by a mass of loose cells called the root cap.
