Question

if the chromosome number in a flowering plant is 20 then find the chromosome number in its endosperm and Egg cell​

Answer 1

Answer:

the chromosome number in its endosperm is 30 and the chromosome number in its egg cell is 10.

Explanation:

the ploidy of the flowering plant is diploid so 2n=20 so n=20/2 and n=10. The ploidy of endosperm is triploid so 3n=30 and the ploidy of egg cell is haploid so n=10

Answer 2

Answer:

Chromosome number for endosperm cell(3n)=30

Egg cell(n)=10

Explanation:

if the flowering plant (angiosperm)is diploid

then (2n)=20

then,n=10

now,endosperm( of flowering plants) is generally triploid (i.e.,3n)=3×10=30

egg cell(n)=10
