Study Notes
Life Cycle and Reproduction
- The period between an organism's birth and natural death is called its lifespan.
Reproduction
- The main function of reproduction in organisms is to produce offspring.
- Reproduction allows the continuation of a species.
Types of Reproduction
- Asexual reproduction results in offspring that are genetically and morphologically identical to their parent.
- Binary fission is a type of asexual reproduction that occurs along the longitudinal axis of the individual.
Asexual Reproduction Methods
- Fragmentation is a type of asexual reproduction where the parent body divides into many daughter organisms.
- Budding involves the formation of a new individual from a bud, and in some cases, leads to a complex budded condition called torulation.
- Vegetative propagation is a type of asexual reproduction that involves the formation of new plants from vegetative parts like root, stem, leaf, etc.
- Regeneration is a type of asexual reproduction that involves the repair of the missing part of the organism by the proliferation of cells.
- Multiple fission is a type of asexual reproduction where a single parent cell divides into many daughter cells simultaneously.
