Study Notes
Reproduction in Plants
- Reproduction is the biological process of producing offspring by a parent, and the offspring may or may not be an exact copy of the parent.
Modes of Reproduction
- There are two modes of reproduction: asexual reproduction and sexual reproduction.
Asexual Reproduction
- Asexual reproduction occurs without the involvement of male and female gametes.
- No seeds are produced in asexual reproduction.
Types of Asexual Reproduction
Vegetative Propagation
- Vegetative propagation occurs through vegetative parts of the plant, such as leaves, stems, and roots.
- Examples of organisms produced by vegetative propagation:
- Onion, garlic, and tulip are produced by stems.
- Sweet Potato and Dahlia are produced by roots.
- Bryophyllum is produced by leaves.
Budding
- A bud is a small bulb-like structure bulging from a yeast cell.
- Budding is the process of producing a new organism from a bud when it gets detached.
- Examples of organisms produced by budding:
- Yeast
- Hydra
Fragmentation
- Fragmentation is the process by which an organism gets divided into two or more parts, and each part grows into a new organism.
