|
| 3592. |
Question : Double fertilization is wonderful phenomenon in flowering plants .explain duble fertilization in flowering plant with help of a diagram. |
|
Answer» Solution :(1) Fertilisation is the process of fusion of make male and female gametes. (2) For the fusion ofmale and female gametes pollen grains have to reach the surface of the stigma. This is CALLED pollination. (3) Pollen grain received by the stigma germinate and give rise to pollen tubes. Only one pollen tube finally reaches the embryosac. (4) This tube will have two male nuclei, which migrate to the tip of the pollen tube at the TIME of fertilization. (5) Usally the pollen tube ENTERS the ovule through micropyle and discharge the two male gemtes into this embryosac. ![]() (6) One male NUCLEUS (gamete) approaches the egg and fuses with it to form a diploid (2n) zygote. this is first fertilisation. ` n oversetuarr O + n underset +O rarr2n ("zygote")` (7) The other male nucleus (gamete) reaches the secondary nucleus (2n) and fuses with it to form endosperm nucleus which will be triploid. this is second fertilization in the embryosac. `n overset uarr O+2n underset +O rarr 3n (P.E.N)` (8) Thus double fertilisation occurs in embryosac which is UNIQUE in flowering plants. |

Question : Does the occurrence of diversity of animals on earth suggest their diverse ancestry also? Discuss this point in the light of evolution. |
| Answer» Solution :Though animals have a VAST diversity in STRUCTURES they probably do not have a COMMON ancestry, because common ancestry may greatly limit the extent of diversity. As many of these diverse animals are INHABITING the same habitat, their evolution by geographical isolation and speciation is also not likely. Thus, a common ancestry for all the animals is not the likely THEORY. | |
| 3598. |
Question : Doesthe occurrence of diversity of animals on earth suggest their diverse ancenstry also? Discuss this point in the light of evolution. |
|
Answer» Solution :Newer organisms arise from the EXISTING ones due to natural selection of the acquired variations. Common ancestry between organisms of different species arises during speciation, in which new species are ESTABLISHED from a SINGLE ancestral population. YET, the fundamentally different body organisations of diversified animal groups SUGGEST diverse ancestry. Thus, a common ancestry for all the animals is not acceptable.. |
