Question

what do you mean by the vegetative , reproductive, senescent phases.​

Answer 1

Answer:

The annual and biannual plants like rice, wheat, marigold, pea, henbane and radish show clear cut vegetative, reproductive and senescent phases. However, in perennial plants like mango and apple, it is very difficult to define these phases.

Answer 2

Senescent phase – It is the time when an organism grows older and loses the reproductive capacity.

Vegetative phase change is the juvenile-to-adult transition in plants. This transition is distinct from the reproductive transition and is most prolonged and pronounced in woody species. Manipulating phase change may be an important avenue for plant improvement.

Reproductive stage in plants is represented by appearance of flowers. In animals the end of juvenile phase is indicated by many of them showing morphological and physiological changes prior to active reproductive behaviour.
