If the number of chromosomes in endosperm of a dicot plant is 36, the root cell will contain
View answer and explanation
Correct option: C
24 chromosomes
Option C (24 chromosomes) is correct because the root cell is diploid (2n) and the endosperm cell is triploid (3n), so 3n = 36, therefore 2n = 24.

Synergid’s filiform apparatus
View answer and explanation
Correct option: D
Both (a) and (c)
Option D (Both (a) and (c)) is correct because the filiform apparatus of synergids guides the pollen tube into the embryo sac and is located near the micropylar end.

The ploidy level of egg apparatus of embryo sac which contains three cells is
View answer and explanation
Correct option: B
Haploid
Option B (Haploid) is correct because the egg apparatus consists of the egg cell and synergids, which are all haploid (n).

Double fertilisation is an unique event to which of the given plant groups?
View answer and explanation
Correct option: D
Angiosperms
Option D (Angiosperms) is correct because double fertilization, involving the fusion of one sperm with the egg and another with the polar nuclei, is a unique characteristic of angiosperms.

Sexual reproduction leads to
View answer and explanation
Correct option: A
Genetic recombination
Option A (Genetic recombination) is correct because sexual reproduction involves the fusion of gametes, leading to the mixing of genetic material and thus genetic recombination.

In flowering plants endosperms are
View answer and explanation
Correct option: D
Triploid
Option D (Triploid) is correct because the endosperm in flowering plants results from the fusion of a sperm nucleus with two polar nuclei, resulting in a triploid (3n) tissue.
18

Vegetative fertilization is also called
View answer and explanation
Correct option: A
Triple fusion
Option A (Triple fusion) is correct because vegetative fertilization refers to the fusion of the second male gamete with the polar nuclei, which is also known as triple fusion.

The arrangement of the nuclei in a normal embryo sac in the dicot plants, is
View answer and explanation
Correct option: B
3+2+3
Option B (3+2+3) is correct because a typical dicot embryo sac has 3 antipodal cells, 2 polar nuclei in the central cell, and 3 cells in the egg apparatus (1 egg cell + 2 synergids).

Choose the mis –matched option.
View answer and explanation
Correct option: D
Birds – Adansonia – Ornithophily
