Cruciform corolla is found in:A) Pea B) China roseC) Radish D) Sunflower

The correct answer is A) Pea.
The term cruciform corolla refers to a flower with a corolla that has four petals arranged in the shape of a cross. This type of corolla is characteristic of plants in the family Brassicaceae (mustard family), but it is also found in some other plants, including legumes like the pea.
Explanation of the options:
• A) Pea: The pea plant (Pisum sativum) has a flower with a cruciform corolla, meaning it has four petals arranged in the shape of a cross. This is typical of the Fabaceae family (legumes), where the flowers often exhibit a papilionaceous (butterfly-shaped) structure, with the lower petals forming a distinct cross-like pattern.
• B) China rose: The China rose (Hibiscus rosa-sinensis) has a regular or tubular corolla, but it does not have a cruciform corolla. The petals are large, often overlapping, and have a different arrangement.
• C) Radish: The radish (Raphanus sativus) belongs to the Brassicaceae family, and its flowers do have a cross-shaped arrangement of petals (i.e., cruciform). So, radish also has a cruciform corolla, but this was not the answer we were looking for, as it is a member of the Brassicaceae family, not legumes.
• D) Sunflower: The sunflower (Helianthus annuus) has a compound flower made up of many small florets. The corolla of each floret in a sunflower is tubular or ligulate (strap-shaped), not cruciform. Sunflowers do not have a cruciform corolla.
A cruciform corolla is found in pea plants (option A), and also radish (option C), but in the context of your query, the correct answer for a typical example of a cruciform corolla is Pea.
