Study Notes
Seed Structure and Function
- Seed coat protects the seed.
- Cotyledon stores food for the embryo.
- Embryo contains the baby plant, consisting of root, stem, and leaves.
Seed Germination
- Germination: Process of a seed sprouting and growing into a new plant.
-
Requirements for germination:
- Suitable temperature.
- Oxygen.
- Water.
- Seed coat falls off during germination.
- Roots are the first part of the plant to emerge during germination and absorb water and minerals.
Photosynthesis
- Photosynthesis is the process performed by leaves to produce food for the plant.
Plant Reproduction
- Stamen is the male part of the flower.
- Anther produces pollen.
- Pistil is the female part of the flower.
- Pollen fertilizes the ovule.
Pollination
- Nectar attracts pollinators.
- Self-pollination occurs within the same flower.
- Cross-pollination involves pollen transfer from the anther of one flower to the stigma of a different flower.
Types of Pollination
-
Flowers pollinated by insects:
- Brightly colored petals.
- Sweet scent.
- Produce nectar.
-
Wind pollination:
- Less colorful petals.
- Light pollen grains.
- Rice plants typically undergo self-pollination.
