13)The Somatic cell of Pea plant has 14 Chromosomes (7 Pairs). Find the number of
Chromosomes in
a. Leaf b. Root c. Male gamete d. Flower

Answer 1

Given Question :

The somatic cell of pea plant ( pisum sativum ) has 14 chromosomes ( 7 homologous pairs ) . Find the number of chromosomes in a) Leaf, b) Root, c) Male gamete, d) Flower.

Answer :

a ) Leaf has 14 number of chromosomes

b ) Root has 14 number of chromosomes

c ) Male gamete has 7 number of chromosomes

d ) Flower has 14 number of chromosomes

Explanation:

• As we know root, leaf and flowers are somatic ( body cells ) , So it number of chromosomes onto each daughter cells will be full number of chromosomes = 14 number of chromosomes ( 2n ) that's ( 2 × 7 ).
• And it's male gamete is a sex ( reproductive cells ) , So it's number of chromosomes only half the number of chromosomes ( only one member of each pair , thus Male gamete has 7 and female gamete has 7 each chromosomes ). Thus, 7 number of chromosomes ( n ) that's ( 7 ).
