Study Notes
Reproduction in Plants
- Plants reproduce to create new individuals.
- This process is different for different plants.
- Reproduction can be asexual or sexual.
Asexual Reproduction
- Asexual reproduction does not involve the joining of male and female gametes.
- New plants are created from parts of the parent plant.
- This way creates new plants identical to the original plant.
- Methods include:
- Vegetative Propagation. New plants grow from roots, stems, leaves, or buds.
- Examples include stem cuttings, root cuttings.
- Spore Formation. Spores are tiny reproductive cells that develop into new plants (e.g., ferns ,mosses, fungi).
- Budding. New individuals develop from the parent organism (e.g., yeast).
- Vegetative Propagation. New plants grow from roots, stems, leaves, or buds.
Sexual Reproduction
- Plants use sexual reproduction to make new plants that are genetically distinct from the parent plant. Male and female gametes combine to form a zygote (fertilized egg).
- This creates a new plant with a unique combination of characteristics from both parents.
- Involves flowers. Male part is stamen and female part is pistil.
- Flowers have male parts to produce pollen(pollen grains).
- Flowers have female parts to accept the pollen (stigma, style, ovary).
- Pollen reaches the pistil through pollination.
- Pollination can be done by wind, water, or animals that carry pollen to different flowers or parts of the same flower.
- Fertilization occurs when the pollen combines with the egg in the ovary to form a zygote.
- The zygote develops into the embryo of a seed.
- The ovary develops into a fruit which protects the seed and helps disperse it.
- Various methods for seed dispersal exist like wind, water, animals.
Modes of Reproduction in Plants
- Two main types of reproduction exist, asexual and sexual reproduction.
- Asexual reproduction produces offspring that are genetically identical to the parent. It's faster and easier, useful for creating many offspring.
- Sexual reproduction produces offspring with unique combinations of characteristics. It ensures genetic diversity, which is important in a changing environment.
