Reproduction in Plants
Q1. Why is reproduction necessary in living organisms?
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. | |
Q4. Give examples of plants, which reproduce by: -
a) Spore formation – Bread Mould, Ferns or Mosses. b) Fragmentation – Spirogyra c) Vegetative propagation by roots – Sweet Potato, Dahlia or asparagus. d) Vegetative propagation by Stems – Potato, Ginger, Sugarcane. e) Vegetative
