Parts of a Flower
- Stigma: Receives and holds pollen during fertilization.
- Anther: Produces and releases pollen grains for reproduction.
- Petals: Serve dual purposes; protect reproductive structures and attract or repel pollinators through color and scent.
- Sepal: Typically green, sepals protect the flower when it is in bud form and provide support to the petals when the flower blooms.
- Ovary: Houses ovules and is responsible for producing eggs (oocytes) and reproductive hormones such as estrogen and progesterone.
- Stem: Provides structural support, elevating flowers, leaves, and fruits for better access to sunlight and air.
- Ovule: The structure that, once fertilized, transforms into a seed, containing the genetic material for the next generation.
- Filament: A component of the stamen, it contains microtubules that facilitate transport within the cell and support the anther.
