Answer:
Explanation:
The fibrous root is one of the small hair-like roots of the fibrous root system. Fibrous roots are derived from the base of the plant. This root system is available mainly in Monocotyledons, Gymnospermae (conifers) and Pteridophyta (ferns). Most of the fibrous roots grow horizontally and very few roots grow vertically to anchor the plant. Most importantly, the fibrous roots are short. They grow near the surface of the soil, not deep into the soil.
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.
<em>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.</em>
<em>Hence, water is really not necessary for fertilization in the angiosperms.</em>
