Study Notes
Plant Reproduction
- Plants reproduce through three methods: asexual reproduction, sexual reproduction, and vegetative reproduction.
Asexual Reproduction
- In asexual reproduction, offspring develop from a parent without the fusion of gametes.
- Only one parent is involved in asexual reproduction.
- Offspring are genetically identical to the parent.
- Types of asexual reproduction include fission, budding, fragmentation, and spore formation.
- Fission occurs when a single-celled organism divides into two or more daughter cells.
- Budding is when a bud forms on the side of the parent cell and eventually detaches to become a new organism.
- Fragmentation is when a part of a filamentous organism breaks off and forms a new organism.
- Spores are special reproductive units that develop asexually on the parent's body.
Vegetative Reproduction
- Vegetative reproduction occurs when a new plant develops from a vegetative part of the parent plant, such as the root, stem, leaf, or bud.
- This type of reproduction is similar to asexual reproduction as it involves mitotic cell division.
- Daughter plants are genetically identical clones of the parent.
Sexual Reproduction
- In sexual reproduction, gametes (sex cells, like sperm and egg) fuse to form a diploid zygote.
- Gametes are haploid, meaning they contain half the genetic material of a new organism.
- The process of gamete fusion is called fertilization.
- The zygote develops into a new individual.
- Offspring are not genetically identical to their parents.
Reproduction in Lower Plants
- Spirogyra is a representative example of a multicellular lower plant.
- Chlamydomonas is a representative example of a unicellular lower plant.
- Chlamydomonas is a haploid, unicellular algae found in freshwater ponds.
- Chlamydomonas has a pear-shaped body with two flagella attached to the narrow end.
