Plant A with combined desired characters that are inherited from parents. Plant B with desired characters are pure. Find out the types of pollination leads to accurance of characters in both A and B.

Wind pollinated plants generally do not show the character

In large number of plants, pollination is carried out by insects. List four characters of flowers that helps insect pollination.

You are supplied with different flowers - paddy, vallisneria and sunflower. (a)Write down the type of pollination among these flowers. (b) Write down any one of the floral characters to suit the pollination.

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 and find out the incorrect statements. a. Plants use two abiotic (wind and water) and one biotic (animals) agent to achieve pollination. b. Majority of plants use abiotic agents for pollination. c. Only a small proportion of plants uses biotic agents. d. Pollination by water is common among abiotic pollinators. e. Pollination by wind is quite rare in flowering plants and is restricted to about 30 genera mostly monocotyledons.
