On germination a seed first produces shoots with leaves, flowers appear later,

(a) Why do you think this happens?

(b) How is this advantageous to the plant?

Answers (1)

Ans.

(a) On germination of the seed, shoots with leaves are produced at first as the plant is gradually entering the vegetative growth phase of the plant. The leaves begin to manufacture food, and the photoperiod follows to determine the flowering of the plant.
The leaves are produced to regulate the process of photosynthesis and produce food, which could be utilised in sexual reproduction. This marks the beginning of the important flowering process as well.

(b) The vegetative phase marks immense growth and aids the plant to gain maturity.Then the process of reproduction commences, and flowering also occurs. The vegetative phase is necessary to prepare the plant for the upcoming process and for it to develop the necessary structures for it. Thug, the vegetative phase of growth is necessary for the survival of the plant species. The flowering phase depends on this phase to provide for nourishment.
