Question
A single pea plant in your kitchen garden produces pods with viable seeds, but the individual papaya plant does not. Explain.
Solution
Pea plant is a dioecious plant bearing bisexual flowers, i.e. the stamen and pistil are present on the same flower. Thus, the single pea plant can produce viable seeds after self-pollination
Papaya is a monoecious plant bearing unisexual flowers and requires crosspollination for viable seed production. Thus, a single papaya plant cannot produce viable seeds.
