The route followed by a sperm from production to fertilization in a flowering plant is A. A sperm cell is produced in the anther, transported to a stigma where it becomes enclosed along with another sperm cell into apollen grain that grows down the style to the ovary enters the ovule and joins with the egg cell B. A pollen grain is produced in the pistil, which explosively eject it into the air where it is transported to a stigma where it forms to sperm cells one of the sperm cells passes through a pollen tube that grows down the style to the ovary enters the ovule and joins with the egg cell C. A sperm cell, enclosed in a pollen grain with another sperm, is produced in the filament, transported to a stigma where it passes through a pollen grain that grows down the style to the ovary enters the ovule and join with the egg cell D. A pollen grain is produced in the anther, transported to a stigma where it produces two sperm cells that pass through a pollen tube that grows down the style to the ovary.

select the correct explanation of double fertilization in angiosperm plants a. The process involves three sperm. One sperm unites with the two polar nuclei to form a triploid primary endosperm nucleus, and each of the remaining two sperm unites with an egg to form a double fertilized embryo sporophyte plant b.
