In flowering plants, the male gametes are formed by

The spores and gametes produced by some members of algae are non motile. Do you agree with the above statement? Give reason

Seeds are formed in angiosperms when male and female gametes get fused. But in some plants seeds are produced without the fusion of gametes. Comment

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.

Assertion: During gamete transport through water (in algae, bryophytes and pteridophytes), a large number of male gametes, fail to reach the female gametes. Reason: To compensate this loss of male gametes during transport, the number of female gametes produced is several thousand times the number of male gametes produed.
