<span>Meiosis is the process of cell division that reduces the chromosome number by half. During the process two phases (two nuclear divisions) occur: Meiosis I and Meiosis II. Meiosis I is the phase of reduction and Meiosis II is the division. So, if a cell under a microscope shows two daughter cells and they aye haploid than this is the stage Meiosis II, in which the cell is divided into two daughter cells.</span><span />
<span>the virus injects the genetic info. this can be RNA or DNA. retroviruses inject RNA. after injection, the host cell transcription/translation machinery is hijacked and starts making virus proteins from the viral genes.</span>
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>
Answer:
