Answer: Haploid cells contain a single set of chromosomes while diploid cells contain two sets of chromosomes. Haploid cells have half the number of chromosomes as in the parent cell while diploid cells contain the same number of chromosomes as the parent cell.
Explanation: Diploid cells contain two sets of chromosomes while haploid cells contain one set of chromosomes. Diploid cells undergo mitosis while haploid cells undergo meiosis. Diploid cells produces two daughter cells in mitosis while haploid cells produce four daughter cells in meiosis. Diploid cells have (2n) number of chromosomes while haploid cells have (n) number of chromosomes. Diploid cells are somatic cells or body cells while haploid cells are sex cells or gametes. Diploid cells are involved in body growth and repair while haploid cells are involved in sexual reproduction.
The vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.
After the fertilisation of the egg by the sperm in a frog, three regions are formed in the zygote. These are:
- Upper animal hemisphere or upper animal pole which shows pigmentation.
- The grey crescent which is a small area with almost no pigmentation. It is present in between the upper animal pole and the lower vegetal pole.
- Lower animal hemisphere or lower vegetal pole which is white in color.
Thus, the vegetal pole of a frog zygote differs from the animal pole in that the vegetal pole has a higher concentration of yolk.
