The formation of a tough wall of sporopollenin around the male gametophyte leads to the production of what end product?   -Ovules -Eggs -Anthers -Stamens -Pollen

The route followed by a sperm from production to fertilization in a flowering plant is: -A sperm cell, enclosed in a pollen grain with another sperm, is produced in the filamentIt is transported to a stigma where it passes through a pollen tube that grows down the style to the ovaryThe pollen grain enters the ovule and joins with the egg cell. -A sperm cell is produced in the antherIt is transported to a stigma where it becomes enclosed along with another sperm cell into a pollen grainThe pollen grain grows down the style to the ovaryIt enters the ovule and joins with the egg cell. -A pollen grain is produced in the pistil, which explosively ejects it into the airThe pollen grain is transported to a stigma where it forms two sperm cells.One of the sperm cells passes through a pollen tube that grows down the style to the ovaryThe sperm enters the ovule and joins with the egg cell. -A pollen grain is produced in the antherIt is transported to a stigma where it produces two sperm…

In plants gametes are produced by what process AND in what stage? mitosis in gametophytes meiosis in sporophytes binary fission in gametophytes meiosis in gametophytes mitosis in sporophytes
