Study Notes
Flower Structure and Function
- The petals of a flower serve to attract pollinators to the plant.
- The male part of the flower, consisting of the anther and filament, is called the stamen.
- The stigma is the top portion of the style and is the receptive surface for pollen grains.
- The ovary is the enlarged lower portion of the style, enclosing the ovule(s).
- The stigma's function is to receive pollen grains.
Floral Organs
- The filament is the part of the flower that bears the anther and connects it to the flower.
- The ovary's primary purpose is to produce seeds and fruit.
Floral Function
- The corolla's role is to attract pollinators and protect the reproductive organs.
Flower Types
- Staminate flowers are male flowers, while carpellate flowers are female flowers.
- Insect-pollinated flowers often have characteristic features such as brightly colored petals, strong scents, and nectar-rich rewards.
Seed Structure and Function
- The micropyle is the small opening in a dicot seed where the pollen tube enters during fertilization.
- Exalbuminous seeds are those that have no separate existence of the endosperm.
- The testa is the seed coat that protects the seed and regulates water uptake.
Seed Development
- The hilum is the long scar along the notch that marks the point of attachment to the seed stalk in a dicot seed.
- The cotyledons are the two fleshy leaves that enclose the nutritive endosperm during embryonic development in a bean seed.
Embryo Development
- The hypocotyl is the region of the embryo that connects the cotyledons to the root and shoot.
- The endosperm's main role is to provide nutrients to the developing embryo in a maize seed.
- The aleurone layer is responsible for secreting enzymes to break down the endosperm during seed germination.
Embryonic Protection
- The colerorhiza and coleoptile partially cover and protect the embryo.
Maize Grain Structure
- The scutellum is a specialized region of the embryo that absorbs nutrients from the endosperm during seed germination.
