25. Why is external water not essential for fertilization in seed plants? A. The sperm cells in seed plants are capable of resisting desiccation.
The gametes that participate in fertilisation of plants are the sperm (male), and the egg cell, and in flowering plants a second fertilisation event involves another sperm cell and the central cell which is a second female gamete. In flowering plants there are two sperm from each pollen grain.

Endosperm is formed when the two sperm nuclei inside a pollen grain reach Nonflowering seed plants The aleurone is the outer layer of endosperm cells,
Gymnosperms and angiosperms are vascular, sporophytedominant plants that produce seeds. Although these heterosporous plants still reproduce by spores, seeds are the primary means of reproduction and dispersal. A seed consists of an embryonic sporophyte and food supply surrounded by a protective coat. Gymnosperms and
