Question: Give the meaning of protandry with example?

Protandry is a biological term that refers to the condition in which the male reproductive organs of an organism mature before the female reproductive organs. This can occur in plants, animals, and even some fungi.

In plants, protandry is often seen in hermaphroditic flowers, which have both male and female reproductive organs. In these flowers, the stamens (male reproductive organs) typically mature before the pistils (female reproductive organs). This ensures that self-pollination does not occur, as the pollen from the stamens cannot fertilize the ovules in the pistils.

Some examples of plants with protandry include:

• Ivy
• Rosebay willowherb
• Maize
• Sugarbeet
• Water lily

In animals, protandry is less common than in plants. However, it is seen in some species of insects, fish, and amphibians. For example, in the salmon, the males mature before the females and compete for mates.

One example of an animal with protandry is the clownfish. Clownfish are hermaphroditic, but they start life as males. As they mature, they can change sex to become females. This is because the dominant female in a group of clownfish produces a hormone that inhibits the other fish from becoming females. If the dominant female dies, the largest male will become female and take her place.

Protandry can also be seen in some fungi. For example, in the mushroom Coprinus comatus, the male reproductive structures mature before the female reproductive structures. This ensures that the spores from the male mushrooms will be dispersed before the female mushrooms are able to produce spores.
