Identify the correct sequence of events during development of seed in plants.
A. Maturation of pollen grains
B. Fertilization
C. Development of fruit
D. Pollination
Choose the correct sequence of events from the options given below
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A, D, B, C
A. Maturation of pollen grains — first. Pollen grains mature in the anther. In over 60 per cent of flowering plants they are shed at the 2-celled stage. The generative cell gives rise to the two male gametes.
D. Pollination — second. The pollen grains are carried from the anther to the stigma of a pistil.
B. Fertilisation — third. The pollen tube carries the male gametes into the embryo sac. There double fertilisation takes place: one male gamete fuses with the egg, the other with the polar nuclei.
C. Development of fruit — last. After fertilisation, the ovules become seeds and the ovary becomes the fruit, so the seed and the fruit develop together at the end.
