If organisms don’t reproduce, then after their death, there would be no organisms left of their species. Thus their species would perish.
Q2. Differentiate between Sexual and Asexual reproduction.
|Sexual Reproduction |Asexual reproduction |
|1. It is characterized by the fusion of two cells (Gametes) usually coming from |1. It is a type of reproduction that does not involve the union of gametes. |
|two parents. | |
|2. New plants are produced from seeds. |2. New individual is produced from a single parent. |
Q3. Differentiate between binary fusion and budding. Draw a well-labeled diagram showing both.
|Binary Fusion |Budding |
|Binary Fusion is an asexual mode of reproduction in which an organism divides |Budding is an asexual mode of reproduction in which a small outgrowth (bud) |
|into two daughter organisms of equal size. Eg.: Binary fusion in Bacteria, algae |appears on the body of the organism. Eg. : Budding in yeast. |
|and fungi. | |
