Assertion An embryo is formed after some meiotic divisions by the product formed after syngamy. Reason: An embryo is the first cell of sporophytic generation.A. Both Assertion and Reson ae true and Reason is the correct explanation of AssertionB. Both Assertion and Reason are true, but Reason is not the correct explanation of AssertionC. Assertion is true, but Reason is falseD. Assertion is false, but Reason are false |
Answer» Correct Answer - C c. Syngamy involves a male gameter and an egg. It forms a diploid product, the zygote, which is known as first cell of sporophytic generation, it divides by mitotic divisions and forms a multicellular structure called the embryo. |

Which of the following statements, support the view that elaborate sexual reproductive process appeared much later in the organic evolution ? (i) Lower groups of organisms have simpler body design. (ii) Asexual reproduction is common in lower groups. (iii) Asexual reproduction is common in higher groups of organisms. (iv) The high incidence of sexual reproduction in angiosperms and vertebrates. Choose the correct answer given below.A. I and IIIB. I and IIIC. II and IVD. II and III |
Answer» Correct Answer - C Asexual reproduction (budding) has been found in most primitive animals like Hydro but over the evolutionary time as the or advanced organisms came into existence, they resorted the sexual reproduction as it ensures the genetic recombination that results in variation. |
