2. Asexual Reproduction Produced from a single parent; offspring are genetically identical to the parent.

3. Definition Asexual reproduction is a mode of reproduction involving only one parent. It results in offspring that are genetically identical to the parent.

4. Types of Asexual Reproduction • Binary fission • Budding • Fragmentation • Spore formation • Vegetative propagation

5. Examples • Bacteria - binary fission • Hydra - budding • Planaria - regeneration • Potato - vegetative propagation

6. Advantages • Faster reproduction • Requires only one parent • Less energy and time • Stable genetic traits

7. Disadvantages • No genetic variation • Poor adaptability to environmental changes • Higher risk of extinction if environment changes

8. Summary Asexual reproduction is quick and energy-efficient but lacks genetic diversity. It is common in simpler organisms and plants.
