Answer

To effectively identify and illustrate the parts of an insect-pollinated flower, the following components should be included: sepals, petals, stamens (which consist of filaments and anthers), and carpels (which include the style, stigma, ovary, and ovules). Below is a description of each part along with a suggested diagram layout.

Parts of an Insect-Pollinated Flower

1. Sepals:
   • Description: These are the outermost parts of the flower that protect the developing bud. They are usually green and leaf-like.
   • Function: Protects the flower before it blooms.
2. Petals:
   • Description: Located just inside the sepals, petals are often brightly colored and attract pollinators such as insects.
   • Function: Attracts pollinators with their color and scent.
3. Stamens (Male Reproductive Part):
   • Filament:
     • Description: A slender stalk that supports the anther.
     • Function: Holds the anther in a position to effectively release pollen.
   • Anther:
     • Description: The part of the stamen that produces pollen grains.
     • Function: Releases pollen for fertilization.
4. Carpels (Female Reproductive Part):
   • Style:
     • Description: A slender stalk that connects the stigma to the ovary.
     • Function: Provides a pathway for pollen tubes to reach the ovules after fertilization.
   • Stigma:
     • Description: The sticky top part of the carpel where pollen grains land.
     • Function: Captures pollen for fertilization.
   • Ovary:
     • Description: The swollen base of the carpel that contains ovules.
     • Function: Houses and protects the ovules; develops into fruit after fertilization.
   • Ovules:
     • Description: Structures within the ovary that develop into seeds after fertilization.
     • Function: Contains female gametes for fertilization.
