Text SolutionText solutionverified iconVerified

Double fertilization leads to the formation of the zygote and primary endosperm nucleus simultaneously. The triploid primary endosperm nucleus divides to form large nutritive endosperm which serves as the source of nutrition for developing an embryo. To ensure the presence of nutritive endosperm, zygote remains dormant for some time.

Direction: Read the following and answer the questions from given below Pollination is the act of transferring pollen grains from male anther of a flower to the female stigma. The goal of every living organism including plants is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds which then germinate to produce new plants. Two types of flowers with their pollination is seen in plants are chasmogamy and cleistogamy. Chasmogamous flowers have strikingly coloured petals and nectar guides/nectaries in contrast to cleistogamous flowers which are minute bud-like. (i) Cleistogamous flowers are strictly autogamous because, they remain: (a) always npen (h) always clnse. (c) always fragraned (d) brightly coloured (ii) In chasmogamy, pollination takes place in: (a) open flower (b) closed flower (c) large flower (d) geitonogamy flower (iii) Advantage of cleistogamy is: (a) higher genetic variability (b) more vigorous offspring (c) no dependence on pollinators (d) vivipary (iv) Even in the absence of pollinating agents, seed-setting is assured in: (a) Commelina (b) Zostera (c) Salvia (d) (v) Identify the features of the type of flower given below:

An advantage of cleistogamy is that
  1. it leads to greater genetic diversity.
  2. seed dispersal is more efficient and wide spread.
  3. each visit of pollinator brings hundreds of pollen grains.
  4. seed set is not dependent upon pollinators.
