[Campbell Biology P.873] Which statement about flower types is correct based on the text? | Practice Question

Which statement about flower types is correct based on the text?

  • A: Complete flowers always have all four basic floral organs.
  • B: All incomplete flowers are sterile.
  • C: Unisexual flowers possess both stamens and carpels.
  • D: Grass flowers are complete flowers.

Explanation

Complete flowers are defined as having all four basic floral organs: sepals, petals, stamens, and carpels. Incomplete flowers lack one or more of these organs. Unisexual flowers are imperfect, meaning they lack either stamens or carpels, but they are not necessarily sterile, as stated in the text. Grass flowers are explicitly mentioned as lacking petals, making them incomplete.
