Answer 1

Stomata are the tiny openings present on the epidermis of leaves that can be observed under the light microscope. They are mainly classified based on their number and characteristics of the surrounding subsidiary cells, there are different types of stomata.

Complete answer:
Anomocytic type is irregular celled stomata -
In this type, the stomata remain surrounded by a limited number of subsidiary cells, which are quite alike to the remaining epidermal cells, in which stomata are embedded. They are surrounded by epidermal cells, which have a fixed shape and size.
Anisocytic or unequal celled stomata -
In this type, stomata remain surrounded by three subsidiary cells of which one is distinctly similar to the other two.
Diacytic or cross celled stomata -
By a pair of subsidiary cells, the stomata are surrounded. These stomatal cells are perpendicular to the guard cell. In this type, stomata remain surrounded by a pair of subsidiary cells, whose common wall is at a right angle to the guard cells.
Paracytic or parallel celled stomata -
In this type, stomata are continuously surrounded by two subsidiary cells, which are parallel to the longitudinal axis of the stomatal pore and guard cells.
So, the correct answer is “Option A”.

Note: Stomata are present on the leaves which helps in gaseous exchange, maintains the moisture balance, facilitates carbon dioxide uptake and release of oxygen during the process of photosynthesis, transpiration, and many more. The Anomocytic type is irregular celled stomata,
Anisocytic is unequal celled stomata, Diacytic is cross celled stomata and Paracytic is parallel celled stomata.
