What to Focus On

  • Flower is a specialized shoot with floral structures.
  • Pedicel supports the flower; sessile flowers lack a stalk.
  • Thalamus is the expanded cup-shaped tip of the flower stalk.

  • Complete flower has all four floral structures.
  • Incomplete flower lacks one or more floral structures.
  • Stamens and carpels are the essential parts.

  • Calyx is the first whorl and is made of sepals.
  • Sepals may be free or fused.
  • Hibiscus has an epicalyx made of episepals.

Common Mistakes to Avoid

A flower has only two parts: petals and sepals.

Any flower with missing petals is incomplete, and any flower with petals and sepals is complete.

Stamens are the female part and carpels are the male part.

Memory Tips

Flower as a specialized shoot

Four floral whorls on the thalamus

Sepals as the bud protectors

Petals attracting insects
