Study Notes
Flower Structure and Functions
- Anther: Male reproductive part, site of pollen (sperm) production through meiosis.
- Filament: Support structure for the anther, helping to position it for effective pollen dispersal.
- Ovary: Encloses and protects ovules as they develop into seeds within the flower.
- Ovule: Contains the female gametophyte, developing inside the ovary and leading to seed formation.
Flower Components
- Petal: Modified leaf, usually colorful, attracting pollinators like insects.
- Sepal: Protective modified leaf covering the flower bud before it blooms; guards against damage.
- Stamen: The collective male part of the flower made up of the anther and filament; responsible for pollen production.
- Stigma: Top part of the ovary, receptive surface for pollen during fertilization.
Female Reproductive Structure
- Pistil: Female part of the flower, consisting of the ovary, style, and stigma, integral for reproduction.
- Style: The slender part connecting the ovary to the stigma, facilitating pollen tube growth.
Additional Flower Structures
- Peduncle: The stem of the flower, supporting the entire structure and connecting it to the plant.
- Receptacle: The thickened part of the stem where floral organs are attached; plays a key role in flower formation.
Other Relevant Terms
- Pollen: Fine powder containing male gametes, essential for the fertilization process in seed-producing plants.
