Question

Examples of staminate flowers?

Answer 1

Hint: The flower and its parts are concerned with sexual reproduction in angiosperms. The flower is considered as a shoot bearing node and modified leaves. A flower arises from a bid-like vegetative branch. A flower having all the four types of floral organs is called complete while in absence of any one or more floral organs is considered an incomplete flower.

Complete answer:
 The flower that contains both the essential floral organs is described as perfect, bisexual, hermaphrodite or intersexual. The flower that bears only one of the two essential floral organs is described as imperfect or unisexual.

The plants that have only male parts or only stamens are called staminate flowers. Examples of staminate flowers are- cucumber, eggplant, chrysanthemum, etc.

i) Cucumber- The staminate flowers are easily distinguished from pistillate flowers. All the flowers are yellow in colour having a single layer of petals. The flowers are directly attached to the stem.
ii) Eggplant- In this also the staminate flowers are similar to cucumber and are directly attached to the stem.
iii) Chrysanthemum – These are clusters of many small flowers called florets. In each chrysanthemum flower's head has pistillate flowers which are called ray florets while staminate flowers are called disc florets. It is generally located towards the bottom of the flower cluster and has a trumpet-like shape. Pollination is easy in this plant and pollen has less distance to travel.

Note: A unisexual flower would be male or staminate (if only stamens are present) and female or pistillate (if only carpels are present). When both the essential organs are absent, the flower is referred to as a neuter. When both types of unisexual flowers are present on the same plant. Such a plant is called monoecious. When only one type of flower is present, it is termed dioecious.
