Dicotyledonous flowers are usually:
Correct answer: D. Pentamerous
- A. Clmerous
- B. Trimerous
- C. Tetramerous
- D. Pentamerous
Explanation
Flowering plants are divided into two broad groups by botanists: monocots and dicots. The distinction between the two is made based on the number of cotyledons present in the seed after the plant germinates. As their names suggest, monocots have one cotyledon, while dicots have two. In pentamerous flowers, the floral parts are either arranged in five or even multiples of five. The dicotyledonous flower commonly has a pentamerous symmetry.
