Question

Anther and filament are the parts of-
a. Style
b. Stigma
c. Stamen
d. Ovary

Answer 1

Hint: While the anthers of most angiosperms release pollen through a rupture along one side of each sac, the anthers belonging to members of the common family liberate pollen through small pores at the anther tip.

Complete answer:
- The style is the element of the pistil which leads to the development of the pollen tube.
- Stigma is the part of the pistil which clasps the pollen.
- Stamen is the male reproductive component of the flower which is composed of two parts the filament which is a stalk that attaches to another bilobed structure that forms pollen grains.
- The ovary is the major female part that leads to the formation of an ovum.

Hence, the correct answer is option (C).

Additional information:
The number and pact of stamens, along with the way in which the anthers release pollen, are important taxonomic features for many flowering plants. The number of stamens is frequently the same as the number of petals. The presence of many stamens is ordinary in many plant families (e.g., Cactaceae, Ranunculaceae, and Rosaceae); most orchids own only one stamen.

In plants with imperfect (unisexual) flowers, the staminate flowers may be borne individually, as in most squash species, or arranged in elongated clusters known as catkins, as is a feature of oaks and willows. Some flowers construct sterile stamens, known as staminodes, which may be flashy or subtle.

Note: The anther is composed of four saclike structures (microsporangia) that create pollen for pollination. Small secretory structures, called nectaries, are habitually found at the base of the stamens; they give food rewards for insect and bird pollinators. All stamens of a flower are together called the androecium.
