Question

The anthers in Solanaceae are
A. Monothecous, introrse
B. Dithecous, extrorse
C. Dithecous, introrse
D. Monothecous, extrorse

Answer 1

Hint:- Anthers are a part of the male reproductive organ called the stamen of flowering plants. The collection of stamens in the flower of a flowering plant is termed as androecium. Each stamen consists of two major parts – a stalk-like structure called filament and a sac-like structure at the tip of the filament called the anther.

Complete answer:
Anthers contain pollens, the prior male reproductive unit of flowering plants. They typically contain two compartments called thecae. Each theca consists of two microsporangia which contain numerous free pollen grains in it. The thecae are interconnected by a tissue called connective tissue. Anthers can be classified based on the number of lobes (thecae). Anthers that have one lobe are called monothecous. On the contrary, anthers having two lobes are called dithecous.
Anthers release the pollen grains by dehisching at definite places. Dehiscence can be accomplished by three methods – introrse dehiscence, extrorse dehiscence, and latrose dehiscence. In introrse type, anthers dehisce towards the gynoecium (female reproductive organ of flowering plants), and in extrorse dehiscence, they burst towards petals and in latrose, they dehisce laterally. In the Solanaceae family, the anthers of the plants are typically dithecous and they dehisce by introrse mode.
Thus, the right option is C.

Note:- Solanaceae are typically a family of dicotyledonous flowering plants, including most herbs. Shrubs and trees are comparatively less common in this family of plants. The family includes plants of major economic importance such as Lycopersicon esculentum (tomato), Solanum tuberosum (potato), Nicotiana tabacum (tobacco), etc. This family is present worldwide, except Antarctica.
