In seed-bearing plants, the develops into the seed following fertilization A. The microsporangium. B. The sporophyte. C. The endosperm. D. The ovule. E. The pollen grain.

Which of the following events must occur before fertilization can happen? A. Double meiosis B. seed coat formation C. endosperm formation D. Pollination E. fruit development

The route followed by sperm from production to fertilization in a flowering plant is: A. 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. B. 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. C. 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. D. A pollen grain is produced in the antherIt is transported to a stigma where it produces two sperm cells that pass through a pollen tube that grows down the style to the ovary.One of the sperm cells enters the ovule and joins with the egg cell. E. A sperm cell, enclosed in a pollen grain with another sperm, is produced in the anther.The pollen is transported to the stigma of the flower, where the two sperm travel down the pollen tube that is growing down the style to the ovary.The sperm enters the ovule via the micropyle and fertilization takes place
