Creative Question:
While watering the guava plant, Nidhita observed that the small guava plant in their garden had grown much
taller in six months. She found out from her mother that it was due to cell division. Later, her mother applied
some organic fertilizer to the plant. Then she asked her mother, "Mother, you are fertilizing the soil, but how
will it reach to the leaves?" "Through a special process," replied her mother.
a) What is cell division?
b) Why is meiosis called reduction division? Explain.
c) How does the longest stage of above mentioned cell division play role in the growth of the plant?(3)
d) Analyze how important the special process in the mother's answer is in the life of the plant.(4)​

Answer 1

a) Cell division is the process by which a parent cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. ... Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions.

b) The cellular division in meiosis I is called the reduction division because it results in the reduction of the chromosome number from diploid (cell has two copies of each chromosome, one maternal and one paternal chromosome) to haploid (cell has only one copy of each chromosome, either maternally-derived or paternally- ...
