Options

• dioecious and bears only staminate flowers

• monoecious

Answer 1

A dicotyledonous plant bears flowers but never produces fruits and seeds. The most probable cause for the above situation is that the plant is dioecious and bears only staminate flowers.

Explanation:

A dioecious plant has separate male and female plants. If it bears only staminate (male) flowers, it cannot produce fruits and seeds since fertilization requires pistillate (female) flowers. Hence, the plant has flowers but no fruits or seeds because it lacks female flowers necessary for fruit formation and seed development.
