Study Notes
Reproduction in Plants
- All living organisms reproduce, which means producing new individuals from parents.
- The process of producing new individuals is referred to as reproduction.
- Plants have two main types of reproduction: asexual and sexual.
Flowering Plants
- Common parts of flowering plants include roots, stems, leaves, and flowers.
- Roots anchor the plant, stems support it, and leaves are involved in photosynthesis.
- Flowers are the reproductive parts of plants and play a crucial role in reproduction.
Asexual Reproduction
- Asexual reproduction occurs without seed production and can create new plants from vegetative parts.
- Vegetative propagation is a type of asexual reproduction where new plants form from roots, stems, leaves, or buds.
Methods of Asexual Reproduction
- Cutting: A branch with a node (where leaves arise) can be buried in soil to grow new plants.
-
Examples of Asexual Reproduction:
- Potato: New plants can sprout from 'eyes' on the potato.
- Ginger: New plants develop from underground parts.
- Bryophyllum: Can produce new plants from buds on leaf margins.
Observational Activities
- Observe a cutting from a rose or champa plant to see root development when buried in soil.
- Examine potatoes for eyes, cut into pieces with an eye, and see them sprout in soil.
- Demonstrate yeast growth, as yeast reproduces through budding.
Vegetative Buds
- Flower buds develop into flowers; vegetative buds in leaf axils can grow into new shoots.
- A bud is a short stem with overlapping immature leaves that can lead to new plants.
Natural Plant Examples
- Sweet potatoes and dahlias can generate new plants from their roots.
- Cacti can produce new plants when parts become detached.
