Question

Sepals are persistent in
A. Solanaceae
B. Brassicaceae
C. Poaceae
D. All of the above

Answer 1

Flowers form the reproductive part of the plant. The flower also has various other parts which make it more beautiful and secured. They are economically useful for mankind. The floral diagram is used to depict the various collective parts of the flower and plant.

Complete answer:
Sepals are the green coloured part of the flower which has the major function of protecting the flower when it is in the bud form. It also supports the petals of the flowers. Petals are the colourful parts of the flower.

Collectively, the sepals form the calyx forming the outermost whorl of the flower.
The sepals and petals together constitute the perianth. The whorl of petals is called the corolla. The petals attract the bees or insects for the pollination. This will make the fertilization possible.

Option A: Solanaceae: This family has 5 sepals joined together in a whorl. They are present along with the fruit and are persistent.

Option B: Brassicaceae: This family has 4 sepals and petals. They shed off after the fruit formation. The family includes mustard cauliflowers etc.

Option C: Poaceae: Bamboos are the members of the Poaceae family. They have monocarpellary and superior ovary. The style may be present or absent. The sepals are present but shade off after the fruit formation.

Hence, the correct answer is option (A).

Note: Solanaceae is called the nightshade plant. They are economically very useful. They have flowering plants. They include both annual and perennial herbs, shrubs and trees. The sepals form a characteristic feature of the angiosperms.
