Explanation:
The seed of an angiosperm is formed as a result of fertilization (fusion of sperm in pollens and the ova from ovary). According to the question, the cells of the seed which will grow into the plant contains 20 chromosomes. Seeds of angiosperms contain a tissue called ENDOSPERM that forms as a result of the unique DOUBLE FERTILIZATION in angiosperms. It occurs when one haploid sperm cell fuses with two haploid polar nuclei to form a triploid endospermic structure that serves as food for the growing embryo in the seed.
Now based on the above explanation, the diploid plant cell with 20 chromosomes will have 10 chromosomes (half as much) in its gametes as a result of meiosis. This 10 chromosomes in each gamete (sperm and ovum) fuses to form a diploid zygote with 20 chromosomes, while one haploid sperm cell (10 chromosomes) also fuses with two haploid polar nuclei (10 chromosomes each) to form a triploid endosperm with 30 chromosomes i.e. 10+10+10.

Cellular communication is the function of the plasma membrane that allows it to respond to certain stimuli from outside the cell and hormones to bind to receptors.
<h3>What is plasma membrane?</h3>
It is a double layer of lipids that covers and delimits the cells, serving as a border between the inside and the outside of the cell, and also allowing a physicochemical balance.
<h3>Characteristics of plasma membrane</h3>
Enables the development of compartments; allows or rejects the entry and/or exit of particles; acts as a mechanical defense; and reacts to external signals and stimuli.
It reacts and transmits information inside the cell, starting certain biochemical processes: cell division, cell movement or the segregation of biochemical substances.
Therefore, we can conclude that the main characteristic of the plasma membrane, that is, its ability to allow or reject the entry of certain molecules into the cell.
