Question

Give 3 examples of pistillate flowers.

Answer 1

Hint: A flower having petals, sepals, stamens and pistils is considered to be a complete flower whereas lacking any one or more of these structures, the flower is said to be incomplete.

Complete answer:
• Androecium is called the male part of the flower and is composed of stamens. Stamens consist of a filament and an anther, which produce pollen grains.

• Gynoecium is called the female part of the flower and is composed of one or more pistils. Each pistil consists of sigma, style and an ovary. The ovary encloses the ovules which later turn into the seeds of the fruit.

• When both stamen, the male sexual reproductive organ of a flower as well as pistils, the female secual reproductive oran of a flower are present in the same flower, it is called bisexual.

• Stamens and pistils may not be present together in a flower. A flower that lacks stamens and only has pistils are known as pistillate flowers. On the other hand, flowers that lack pistils and only have stamens are called staminate flowers.

• Examples of pistillate flowers are Chrysanthemum, cucumber, eggplant, squash etc.
When the same plant grows flowers of both the sexes, it is called a monoecious plant.

Note: The male flowers (Staminate flowers) are obviously unable to produce fruit. When there are male, female as well as bisecual flowers on the same plant, the plant is said to be polygamous. On the other hand, when male and female flowers are present on two different plants, the plant is said to be dioecious.
