The cell wall contains not only cellulose and protein, but other polysaccharides as well. The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.
Answer: All organisms multiply or reproduce their own kind. In plants there are two modes of reproduction, asexual and sexual. There are several methods of asexual reproduction such as fragmentation, budding, spore formation and vegetative propagation. Sexual reproduction involves the fusion of male and female gametes.

Chromosomes are the building blocks of life.
These materials are found in every cell's nucleus and are made from multiple
strands of DNA (Deoxyribonucleic Acid). Without chromosomes living organisms
will not exist because it is the main recipe for making life. Each human body
normally contains forty-six chromosomes, twenty-three of which came from the
sperm, while the other half came from the egg during the process of reproduction.
<span>When a DNA is further segregated into parts,
segments of these strands are called genes. Genes are responsible for adding
multiple protein parts that ultimately make the body’s muscles, organs, bones,
and every other process that makes a living thing function.
</span>
Genes usually come in pairs. But they tend to
appear in different parts of the chromosome. These genes that appear on a
particular chromosome are called alleles. Alleles, give a person a dominant trait
that he/she inherited from his/her parents. If an allele is dominantly leaning
on the gene side of the mother, one could possibly inherit her blood type or
even her colorblindness.
<span>These three building blocks found in the smallest
part of the cell called nucleus, make one person unique from the rest of the
world. The correct balance of these three elements would then give birth to a
living and functioning organism.</span>
