Read the following statements and find out the incorrect statement.
1 In organisms, exhibiting internal fertilisation the male gamete is nonmotile but in seed plants the male gamete is motile.
2 Organisms exhibiting external fertilisation show great synchrony between the sexes and release a large number of gametes into the water in order to enhance the chances of syngamy.
3 In frogs and bony fishes, large number of offsprings are produced as they are extremely vulnerable to predators threatening their survival up to adulthood.
4 In organism exhibiting internal fertilisation, even though the number of sperms produced is very large, there is a significant reduction in the number of eggs produced.
Explanation:
In organisms, exhibiting internal fertilisation, the male gamete is either motile or non-motile but female gamete are always non-motile. In seed plants the male and female gamete are non-motile.

Animals in which development of zygote takes place inside the body of female parent, i.e., they give birth to young ones are called
1 Oviparous
2 Viviparous
3 Ovoviviparous
4 Marsupials
Explanation:
Viviparous animals are those in which the zygote develops within the mother's body and the females directly give birth to young ones.

Every sexually reproducing organism, including human beings, begin life as a single cell called
1 Gamete
2 Spore
3 Embryo
4 Zygote
Explanation:
Every sexually reproducing organism, including human beings, begin life as a single cell called zygote.

Embryogenesis is process of development of embryo from the zygote in diploid organisms. During this process zygote undergoes:
1 Meiosis
2 Cell division (mitosis)
3 Cell differentiation
4 Both (2) and (3)
Explanation:
During embryogenesis, zygote undergoes cell division (mitosis) and cell differentiation. While cell divisions increase the number of cells in the developing embryo; cell differentiation helps groups of cells to undergo certain modifications to form specialised tissues and organs to form an organism.

Which is incorrect about flowering plant?
1 After fertilisation the ovary develops into fruit and ovules develops into seed
2 The ovary wall after syngamy converted into pericarp which is protective in function
3 The zygote is formed inside the ovule
4 None of the above
Explanation:
In flowering plants, the zygote is formed inside the ovule. After fertilisation the ovary develops into fruit which develops a thick wall called pericarp that is protective in function. The zygote develops into embryo and the ovules develop into the seed.
