Question

Mention in detail of the number of chromosome in the
somatic cell of a flowering plants in 8. What would be
number of chromosome in (a) egg, (b) endosperm
, (c) pollen
grain, (d) pollen tube.​

Answer 1

Somatic cell is diploid. So the haploid number of chromosome is 4

(I)Egg is haploid-4

(II)endosperm is triploid-12

(III)pollen grain is haploid-4

(IV)pollen tube is haploid-4

Please mark me as brainliest... very urgent... Hope it helps

Answer 2

Answer:

The pollen tube contains 12 chromosomes and 3 haploid nuclei, so each nucleus will have 4 chromosomes. If each sperm nucleus has 4 chromosomes, then the egg must also have 4 chromosomes and the diploid number for the plant must be 8.
