Question

Which one of the following statements regarding post-fertilization development in flowering plants is incorrect ?
(1) Ovary develops into fruit
(2) Zygote develops into embryo
(3) Central cell develops into endosperm
(4) Ovules develop into embryo sac

Answer 1

Answer:

(4)ovules develop into embro sac

Explanation:

as ovules develop into seed

Answer 2

The correct answer is Option 4.

• Because, Ovules do not develop into embryo sac, rather it develops into seed.
• These development occurs in post-fertilization phase.
• The fertilization occurs after the pollen from a male flower mates with a ovule of female flower.
• Seeds are found both in gymnosperms(closed seed) and angiosperms(naked seed).
• The total chromosome number in seed is 3n (where n = number of haploid chromosome.)
• Example, if a plant has 3 haploid chromosome then total chromosome will be 3*3 = 9.
