Text SolutionText solutionverified iconVerified

Formation of endosperm before fertilization is seen in grasses, because of double fertilization. In grasses, the sperm cell emerges from the pollen tube and fuses with the egg cell and 2 polar nuclei. The fusion of one sperm cell and polar nuclei forms the endosperm nucleus. The fusion of the 2nd sperm cell with the egg cell gives rise to the zygote.

  3. Microbes are being grown on an industrial scale as source of good protein. Blue-green algae like Spirulina can be grown easily on materials like waste water from potato processing plants (containing starch), stram, molasses, animal manure and even sewage, to produce large quantities and can serve as food rich in protein, minerals, fats, carbohydrate and vitamins. Incidentally such utilisation also reduces environmental pollution.

plants to various kinds of stresses. What do you understand by vernalisation? Write its significance. 1) Vernalisation is the method of inducing flowering in plants by pre-chilling treatment. 2) Significance: It prevents precocious reproductive development late in the growing seasi and enables the plant to have sufficient time to reach maturity. Define the terms quiescence and dormancy. [AP MAR-15] 1) Quiescence: It is a delayed seed germination which occurs when a seed fails to germinat because the external environmental conditions are too dry or warm or cold for germination 2) Dormancy: It is the innate inhibition of seed germination even a seed is placed in mos favourable environment for germination.
