Question

In which of the following pairs both plants exhibit epigynous flowers and axile placentation?

• A. Guava and Tomato
• B. Brinjal and Mustard
• C. China rose and Petunia
• D. Cucumber and Sunflower

Hint:

Remember: - Epigynous = inferior ovary, e.g., guava, tomato. - Axile placentation = ovules attached to central axis, typical in compound ovaries. Identifying flower types and placentation helps in plant identification.

Answer 1

The Correct Option is A

Step 1: Define epigynous flowers 
In epigynous flowers, the ovary is inferior (below other floral parts), and sepals, petals, and stamens appear to arise from the top of the ovary. 
Step 2: Define axile placentation 
Axile placentation is when the ovules are attached to a central axis in a multilocular ovary, commonly seen in plants with compound ovaries. 
Step 3: Analyze each pair for epigynous flowers and axile placentation 
(1) Guava and Tomato: Both have epigynous flowers and axile placentation. 
(2) Brinjal and Mustard: Brinjal has epigynous flowers and axile placentation; Mustard has hypogynous flowers and basal placentation. 
(3) China rose and Petunia: Both have hypogynous flowers and parietal placentation. 
(4) Cucumber and Sunflower: Cucumber has epigynous flowers but parietal placentation; Sunflower has epigynous flowers with basal placentation. 
Step 4: Conclusion 
Only Guava and Tomato both exhibit epigynous flowers and axile placentation.
