Presentation Transcript

  1. #115 Class Notes: Flowers • Many plants (angiosperms) contain flowers where the sex cells are contained for the plant’s reproduction. • The stamen is the male organ for reproduction and is composed of the anther and filament (or stalk).

  2. At its tip is the anther, the organ that produces the pollen. • Pollen is composed of fine grains that contain the male sex cells.

  3. The pistil is the female organ; its parts include the stigma, style, and ovary. • During pollination, male pollen lands on the stigma, germinates and the sperm cells travel down the style, and fertilize the eggs in the ovary. The fertilized eggs develop into seeds.

  4. Sepals are the leaf-like parts under the petals. • They are usually green and photosynthetic (able to produce food with the sun’s energy). • Petals can be all colors, shapes, and smells which serve to attract pollinators.
