Which of the following flowers will have higher possibility of self pollination a.Mustard, b.Watermelon, c.Papaya, d.Hibiscus?(CBSE 10TH BIOLOGY BOARD EXAM QUESTION)

 

The flower with the highest possibility of self-pollination among the options is Hibiscus.

Here’s why:

• Mustard – Can self-pollinate, but also cross-pollinates frequently.

• Watermelon – Plants are usually unisexual (male and female flowers separate) → favors cross-pollination.

• Papaya – Mostly dioecious (male and female flowers on separate plants) → only cross-pollination possible.

• Hibiscus – Bisexual flower (both stamens and pistil in the same flower) → high chance of self-pollination if not prevented by mechanisms like protandry or self-incompatibility.
