Study Notes
Plant Reproduction
- Reproduction is a biological process where living organisms produce new individuals of the same species. This process is essential for species survival and allows for genetic variation and adaptation.
- Important functions of reproduction include species continuity, genetic diversity, and replacing individuals.
- Plants reproduce asexually or sexually.
- Asexual reproduction involves one parent and produces genetically identical offspring.
- Sexual reproduction involves two parents and produces genetically diverse offspring from the fusion of male and female gametes.
Types of Asexual Reproduction
- Budding: A bud forms on the parent plant and detaches to become a new individual.
- Fragmentation: The parent plant breaks into fragments, each of which can grow into a new plant.
- Spore formation: Spores develop on the parent plant and can grow into new plants under suitable conditions.
- Tubers: Swollen underground stems that store nutrients (e.g., potatoes).
- Rhizomes: Horizontal underground stems that produce new shoots (e.g., ginger).
- Cuttings: Taking a part of a plant (like a stem) and planting it to grow a new plant.
Types of Sexual Reproduction
- Pollination: Transfer of pollen from the male anther to the female stigma.
- Self-pollination: Pollen from the same flower fertilizes ovules.
- Cross-pollination: Pollen from one flower fertilizes ovules in another flower.
- Fertilization: Fusion of male and female gametes to form a zygote.
- Seed Formation: The fertilized ovule develops into a seed, and the ovary develops into a fruit.
- Dispersal: Spreading seeds to reduce competition among seedlings and occurs through wind, water or animals.
Advantages of Asexual Reproduction
- Rapid population increase
- Requires one parent
- Preserves successful traits
- Efficient in stable environments
Advantages of Sexual Reproduction
- Increased genetic diversity
- Adaptability to changing environments
- Allows for evolution
- Enables the expression of varied traits
Differences Between Asexual/Sexual Reproduction
| Feature | Asexual Reproduction | Sexual Reproduction |
|---|---|---|
| Parent Involvement | Single parent | Two parents |
| Gamete Formation | No gametes formed | Gametes formed through meiosis |
| Genetic Variation | Offspring are clones of the parent | Offspring have genetic variation |
| Fertilization | No fertilization occurs | Fertilization occurs |
| Reproductive Structures | Does not need specialized reproductive organs | Requires specialized reproductive organs (e.g., flowers) |
| Types of Organisms | Common in prokaryotes and some eukaryotes | Common in most multicellular organisms |
| Speed of Reproduction | Generally faster | Generally slower |
| Adaptation Potential | Limited adaptability | Higher adaptability |
