Study Notes
Reproduction in Plants
- Plants reproduce to create new individuals similar to themselves.
- Reproduction is the biological process where parents produce new offspring.
- Plants have vegetative parts like roots, stems, and leaves.
- The flower is the reproductive part of a plant.
- A seed can germinate and grow into a new plant.
- Plant reproduction has two main types: asexual and sexual.
- Asexual reproduction does not involve seeds.
- Sexual reproduction relies on seeds for new plant growth.
- Some plants, like sugarcane, potatoes, and roses, reproduce without seeds.
Asexual Reproduction
- Asexual reproduction is reproduction that doesn't involve the joining of gametes.
- Asexual reproduction creates new plants from the parent plant's vegetative parts.
- Asexual reproduction is also called vegetative propagation.
- New plants develop from roots, stems, and buds.
Vegetative Propagation
- Vegetative propagation is producing new plants from a parent plant's vegetative parts.
- Examples include cuttings, budding, and grafting.
- A cutting is a piece of a stem.
- Cutting, budding, and grafting propagate plants like roses and money plants.
- A cutting needs at least one node for new plant growth.
- New roots and branches develop from a node.
- Budding involves placing a bud on another plant's stem.
- Grafting involves attaching a rooted plant part onto another plant.
- In budding and grafting, the bud or root comes from a different plant.
- Vegetative propagation is faster than sexual reproduction.
- It allows for many new plants quickly.
- New plants are genetically identical to the parent plant, maintaining the same characteristics.
- New fruits can be produced rapidly
Types of Vegetative Propagation
- Plants like potatoes, ginger, and turmeric reproduce using their stems.
- Potato "eyes" are buds that create new plants.
- Ginger and turmeric are propagated through stem cuttings.
- Bryophyllum plants use buds on leaf margins for reproduction.
Other Asexual Reproduction Methods
- Micropropagation: Lab-based asexual reproduction using small plant parts.
- Fragmentation: Asexual reproduction where a parent plant breaks into fragments, each forming a new plant. Common in algae.
- Spore Formation: Asexual reproduction involving spores – microscopic, single-celled structures that become new plants. Common in fungi.
Spore Formation in Fungi
- Fungi reproduce asexually by producing spores.
- Spores release from the sporangium at a fungal hypha tip.
- Wind or water disperse spores.
- Spores can withstand harsh conditions.
- Spores germinate into new fungal colonies when conditions are favorable.
