In some plants self pollination is prevented by genetic mechanism of either pollen or pistil.
Why does such process not lead to seed formation?

Text Solution

Verified by Experts

It is because of interaction between the chemicals of the pollen and those of stigma ( Pollen-pistil interaction )

Why does self-pollination not lead to seed formation in self-incompatible species?

Assertion, Geitonogamy is functionally cross-pollination involving pollinating agent and genetically it is similar to autogamy since the pollen grains come from the another plant. Reason: Geitonogamy is the only type of pollination which during pollination brings genetically different types of pollen grains to the stigma.

Read the following statements and find out the incorrect statements. a. In majority of organisms, male gamete is motile and female gamete is non-motile (stationary). b. In algae and fungi, both male and female gametes are non-motile. c. In seed plants, pollen grains are the carrier of male gametes and ovule has the egg. d. In dioecious plants, pollination facilitates transfer of pollen grains to the stigma. e. In monoecious animals, since male and female gametes are formed in different individuals, the or ganism must evolve special mechanism for gamete transfer.

Read the following statements carefully and select the appropriate option given below. (i) Bisexual animals that possess both male and female reproductive organs, are hermaphrodites. (ii) In seed plants, pollen grains are the carriers of male gametes and ovule have the egg. (iii) Events in sexual reproduction before the formation of zygote are called post-fertilisation events. (iv) Sexual reproduction involves the formation and fusion of gametes, (v) Animals are categorised into oviparous and viviparous based on whether the development of the zygote takes place outside the body of the female parent or inside.
