The role of double fertilisation in angiosperms is to produce
1 Cotyledons
2 Endocarp
3 Endosperm
4 Integuments
Explanation:
Double fertilisation produced one diploid cell and one triploid cell. The diploid zygote will divide and grow to produce an embryo. The triploid cell grows into the endosperm and will nourish the developing embryo.

If root of a flowering plant has 24 chromosomes, then its gamete has how many chromosomes?
1 24
2 12
3 4
4 8
Explanation:
If root of a flowering plant has 24 chromosomes then gamete has 12 chromosomes because gametes are haploid in nature and flowering plant has diploid in nature. So, gametes become half of the total chromosome number.

The movement of pollen tube is called
1 chemotropism
2 thermotaxis
3 thermonastic
4 hydrotropism
Explanation:
The movement of pollen tube is called as chemotropism. Chemotropism may be defined as the movement or the growth of the organism in response is termed positive if the growth or movement is towards the stimulus and is termed negative if it is away from the stimulus.

In some organisms, karyokinesis is not followed by cytokinesis as a result of which, multinucleate condition arises leading to the formation of syncytium. The perfect example for this is
1 appearance of a furrow in cell membrane
2 liquid endosperm in coconut
3 sexual reproduction
4 fertilization
Explanation:
In some organisms, karyokinesis is not followed by cytokinesis as a result of which, multinucleate condition arises leading to the formation of syncytium. The perfect example for this is liquid endosperm in coconut. The liquid endosperm in coconut is an example of nuclear endosperm.
