Answers & Comments
Answer:
1. Asexual reproduction does not involve sex cells or fertilisation. Only one parent is required, unlike sexual reproduction which needs two parents. Since there is only one parent, there is no fusion of gametes and no mixing of genetic information. As a result, the offspring are genetically identical to the parent and to each other. They are clones.
2. Fragmentation is a type of asexual reproduction when a living being breaks into various pieces or smaller pieces of itself. While regeneration is a process where there is complete or partial regrowth of damaged tissues in any living organism.
3. Vegetative propagation is an asexual method of plant reproduction that occurs in its leaves, roots and stem. This can occur through fragmentation and regeneration of specific vegetative parts of plants.
4. To propagate a cactus, you can remove one of the smaller new plants around the base of the main plants.
