A particular species of plant produces light, non-sticky pollen in large numbers and its stigmas are long and feathery. These modifications facilitate pollination by

Which of the following features is/are common to both wind and water pollinated flowers I. Pollen grains are long and ribbon-like, II. Stigma is large and feathery, III. Flowers are not colourful, IV. Flowers are not colourful

State True of False (i) Light nd non sticky pollen grains are characteristic of wind pollinated floweres (ii) Dioecious conditin in plants prevents xenogamy

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 fingi, both male and femla egaetes are non-motile. c. In seed plants, pollen grains are the carrier of male gaemtes and ovule has the egg. d. In dioecious plants, pollination facilitates trasnfer of pollen grains to the stigma. e. In monoecious animals, since male and female gametes are formed in different individuals, the organism must evolve special mechanism for gamete transfer.
