Question

The function of anther is
A. Produce Ubisch bodies
B. Produce pollen grains
C. Store and protect pollen grains
D. All the above

Answer 1

Hint: The flower is the main reproductive part of the plant. There are two types of reproductive parts found in a flower which are the male reproductive part and the female reproductive part. Both reproductive parts of the flowers are made up of different parts.

Complete answer:
A complete flower is composed of sepals, petals, stamens, and pistils. There are two different parts found in a complete flower which are the vegetative part and reproductive part. While the sepals and petals belong to the vegetative part, the stamens and pistils belong in the reproductive part.
In a flower, there are two types of reproductive parts; the male reproductive part and the female reproductive part. A flower may possess only female parts or only male parts, or both.
The male reproductive part of the flower is called stamen which is also known as androecium. This organ is composed of two parts which are known as the anther and filaments. The filament is a slender, thread-like structure. This mainly supports the anther.
The anther is an integral part of the male reproductive part. The anthers arise high from the flower's centre on long filaments. The numbers of anthers differ in the different flower species. But in general, most of the flowers hold five to six anthers that circle the centre of the flower. It is a yellowish and sac-like structure.
The anthers are mainly involved in producing the pollen grains. The transfer of pollen causes reproduction which leads the plant to develop seeds and produce a new generation of infant plants. However, it does not protect the pollen grains but produces the grains for pollination and fertilisation.
Ubisch bodies are present as small acellular bodies in the tapetal layer and help in the development of the pollen grains. They are found in the cytoplasm during the spore wall formation.

Therefore, the correct option is option B.

Note: A complete flower mainly consists of four parts. These are sepals, petals, stamens, and pistils. The flower is the main reproductive part of the plant. The stamen is the male reproductive part and the pistil is the female reproductive part. There are two parts found in a stamen which are the anther and filaments. The main function of anthers is to produce pollen grains.
