Question

How much time is generally required or taken by the pine plant from pollination to fertilization?
A. Four months
B. Thirteen months
C. Two years
D. Four years

Answer 1

Hint: Hydrated by the pollination drop, the pollen grain now germinates into the spongy nucellar tissue. The pollen tube then halts its increase midway through the nucellus for the duration of the lengthy interval between pollination and fertilization. A total of 13 months of duration is taken by the pine plant from pollination to fertilization.

Complete answer:
A pine plant carries both quite male and kind of woman gametes, which especially is pretty big. It subtly produces cones. The quiet woman comes true on the particular top branches and the fairly male cone forms are underneath them, which is quite great. Pollination takes region with the help of wind, which sort of indicates that a pine plant contains each pretty male and form of girl gametes in an essentially massive manner. The very male cones specifically produce pollen grains that attain the absolute woman cones on without a doubt other plants and fertilize the ovule, demonstrating how it subtly produces cones. These woman pine cones for all intents and functions take around thirteen months for fertilization, demonstrating how pollination takes area with the help of wind, which indicates that a pine plant contains each kind of male and really girl gametes in a pretty big manner.
Hence, the correct answer is “Thirteen months is the time taken for a pine plant from the stage of pollination to the stage of fertilization”.
So, the correct answer is “Option B”.

Note:
All conifers sincerely are pollinated through the wind, which for the most component in all fairness giant. Pollen might also for the maximum component be produced in massive portions, mainly with the aid of species of proper pine, that may blanket the surface of mainly close by lakes and ponds with a kind of yellow scum of pollen, demonstrating how all conifers for the maximum element are pollinated through the wind in a kind of huge manner.
