In oomycetes female gamete is smaller and motile, while male gamete is larger and non-motileD. Chlamydomonas exhibits both isogamy and anisogamy and Fucus shows oogamy |
|
Answer» Correct Answer - C Oomycetes include water moulds, white rusts and downy mildews. In these, female gamete is smaller and motile, whereas, male gamete is smaller and motile. Isogametes are found in algae like Ulothrix, Chlamydomonas, Spirogyra, etc., Which are similar in structure, function and behaviour. Anisogametes are found in Chlamydomonas in which one gamete is larger and non-motile and the other one is motile and smaller. Oogamy is the fusion of non-motile egg with motile sperm. The gametes. differ both morphologically as well as physiologically. It occurs in Chlamydomonas, Fucus, Charac, Volvox, etc. |

With which type of reproduction do we associate the reduction division? Analse the reason for it. |
|
Answer» Reduction division (meiosis) is associated with sexual reproduction. The reasons are (i) Since, sexual reproduction involves the fusion of two types of gametes male and female), they must have haploid gametes. (iii) Reduction division also ensures maintenance of constancy of chromosome number from generation to generation. |
