Study Notes
Flower Structure and Types
- Flowers are essential reproductive structures in flowering plants, responsible for species survival.
- A complete flower includes all four floral structures: sepals, petals, stamens, and carpels.
- Incomplete flowers lack one or more of these structures, making them unisexual (either male or female) or perfect (both male and female).
- Male flowers have only stamens (staminate), while female flowers contain only carpels (pistillate).
Floral Parts
- Nectaries: Produce nectar, a sweet liquid that attracts pollinators like bees. Usually located at the base of the petals or pistil.
- Sepals (Calyx): Green leaf-like structures that protect the bud and may photosynthesize. Can be separate (polysepalous) or fused (gamosepalous).
- Petals (Corolla): Brightly colored structures that attract pollinators. Can also be free (polypetalous) or united (gamopetalous) into a tube.
- Stamens (Androecium): Male reproductive parts consisting of a filament and bilobed anther, which produces pollen.
- Carpels (Gynoecium): Female reproductive parts composed of ovary, style, and stigma. The ovary contains ovules that develop into seeds.
Flower Types
- Bisexual (Hermaphrodite) Flowers: Contain both stamens and carpels, allowing for self or cross-pollination.
- Unisexual Flowers: Contain only one type of reproductive organ. Examples include papaya (male) and palms (female).
- Neuter Flowers: Lack both stamens and carpels, such as ray florets in sunflowers.
Whorls of a Flower
- Flowers are organized into whorls:
- First whorl: Sepals
- Second whorl: Petals
- Third whorl: Stamens
- Fourth whorl: Carpels
- Essential whorls are involved in reproduction, while non-essential whorls support and attract pollinators.
Inflorescence and Floral Arrangement
- The arrangement of flowers on a plant is termed inflorescence, influencing reproductive strategies and efficiency.
Additional Facts
- Bracts: Leaf-like structures that can be colored and may resemble petals, providing additional attraction to pollinators.
- Petaloid and sepaloid perianth refers to the differentiation in the appearance of floral parts when sepals and petals are not distinctly colored.
Review Questions
- Key concepts include parts of flowers that relate to reproduction and the understanding of complete and incomplete flowers.
- Recognize the role of different parts: ovary in fruit formation and ovule in seed generation.
