Study Notes

Flower Structure and Function

Petals: Brightly colored parts that attract insects, facilitating pollination.
Stamen: The male reproductive part of the flower, composed of the anther and filament.
Anther: Responsible for producing male gametes, known as pollen.
Filament: A supporting structure for the anther, positioning it for optimal access by insects.
Ovary: Contains ovules and transforms into fruit after fertilization.
Ovule: The female reproductive structure in seed plants that produces the egg gamete.
Pistil: The collective term for the female parts of the flower, which include the stigma and style.
Stigma: The sticky surface at the top of the style, where pollen grains typically adhere.
Style: The elongated portion of the pistil located between the ovary and stigma; it allows the growth of the pollen tube.
Pollen: The male gamete carrying half of the genetic material necessary for new plant development.
Stalk: The support structure for the flower, aiding in elevation and stability.
Sepal: The outer covering of the flower bud, providing protection before blooming.
Meiosis: A type of cell division that results in the formation of gametes, occurring within the ovary and anther of the flower.
