Question

Angiosperms do not need water for fertilization. Why? (3 points) Group of answer choices Flagellated sperm travel to the ovary inside the pistil Pollen stays inside the cone scales to fertilize eggs A pollen tube grows from the pollen grain into the ovary The sporophytes grow directly from the gametophytes

Answer 1

Answer:

A pollen tube grows from the pollen grain into the ovary

Explanation:

Water is needed for fertilization in several plant groups because the sperm needs to swim to meet the non-motile eggs of the female organs.

However in angiosperms, the pollen germinates and a structure known as pollen tube which contains the male gametophyte (sperm) grows into the ovary where the ovule is located and the male gametophyte is deposited in the ovule to initiate the fertilization process.

Hence, water is really not necessary for fertilization in the angiosperms.
