Question

Which of the following types of anther is found in Malvaceae?
A. Monothecous
B. Dithecous
C. Polytocous
D. Without the us

Answer 1

Hint: Flowers contain the plant’s reproductive structures. There are two reproductive structures found which are male and female reproductive structures. There is a part found in the male reproductive organ which developed the pollen grains is known as another.

Complete answer:
The group of flowering plants is known as angiosperms. Flowers are reproductive structures and can be made up of different parts such as petals, sepals, calyx and corolla. Petals are the bright-coloured part and sepal is the green-coloured part beneath the petals. The sepals are collectively called the calyx which helps to protect the rising bud. The second whorl is composed of petals which are collectively called the corolla. Generally, the flower possesses the reproductive organ in the angiosperms. The flowers consist of two important parts of the reproductive system found in plants. One is the female reproductive part and the other is the male reproductive part. The female parts of the reproductive organ are called megaspores, which will divide to form the egg cell and it is enclosed in the carpel. The stamens are the male reproductive part. In the male reproductive cells, microspores are present which will produce pollen grains. The male reproductive part of angiosperms or stamens consists of two parts, one is filaments and the other part is anthers. Anthers are present in the top of filaments and are lobed shaped structures. Here the anthers are bilobed. In each lobe of anthers, two thecae are found.
In the family of Malvaceae, some of the well-known species of this family are okra, cotton, cacao, and Hibiscus. In the case of the plants of this family, the flowers are generally born in the definite or indefinite axillary inflorescence. The stamens of these flowers are usually very many with filaments but it possesses monothecous anthers.
Thus, the right option is A.

Note: A flower is an important part of a plant because it acts as the reproductive structure of the plant. In a flower, there are two types of reproductive structures which are male and female reproductive structures. The male reproductive structure is known as stamens which contain two parts; anthers and filaments. In the anthers, there are generally four cases. In the case of the plants belonging to the family Malvaceae, the anthers have a single theca therefore it has monothecous anthers.
