The main function of the flower stock is transporting food in the form of water and nutrients to different parts of the plant with the help of xylem and phloem. Xylem helps in transporting cells that help in carrying water and minerals from the roots while phloem transports food in the form of sugar to all parts of the plant. The stock also helps in keeping the the flower steady above the plant folliage. This directly helps in the process of pollination of the plant. The flower that is held steady above the folliage attracts bees and other insects through which it continues the process of pollination.

Explanation:
a) The main characteristic of homologous chromosomes is that they have an equal size. There is a difference in size on both chromosomes.
b) In number one, two chromosomes are homologous. In number two also two chromosomes are homologous. On the other hand, the chromosomes at number one and two are different. Each chromosome has two sister chromatids.
c) A DNA molecule has a double helix, that is, two chains. When a DNA chain is broken and a chromatide has a DNA chain, then two chromatids make up a chromosome and a DNA chain, in this way there are eight dsDNA molecules
d) If each chromosome contains a centromere, therefore, there are four centromeres on all four chromosomes.
e) If a chromosome contains four telomeres, therefore there will be sixteen telomeres.
f) The function of cohesin is to regulate the separation of chromatids in the cell division process. When DNA replication is complete, the DNA compacts and condenses to form mitotic chromosomes.
g) The CENPA protein is encoded by the CENPA gene.
