Question: 

 How many type of stomata are found in plants 

(1).1 

(2).2 

(3).4 

(4).5

 Answer:

correct option (4).5

Explanation:

Stomata:

Stomata are the tiny openings present on the epidermis of leaves. We can see stomata under the light microscope. In some of the plants, stomata are present on stems and other parts of plants.  

Types of Stomata:

There are five types of stomata and they are mainly classified based on their number and characteristics of the surrounding subsidiary cells. Listed below are the different types of stomata.

Anomocytic Stomata:

They are surrounded by epidermal cells, which have a fixed shape and size.  The stomata appear to be embedded in epidermal cells. There is no definite number and arrangement of cells surrounding the stomata.

Anisocytic Stomata:

Stomata are surrounded by three subsidiary cells having unequal sizes, one is smaller compared to the other two.

Diacytic Stomata :

The stomata are surrounded by a pair of subsidiary cells that are perpendicular to the guard cell.

Paracytic Stomata:

The stomata are continuously surrounded by two subsidiaries, which are arranged parallel to the stomatal pore and the guard cells.

Gramineous Stomata:

Each stoma possesses two guard cells, which are shaped like dumbbells. The subsidiary cells are parallel to the guard cells. The guard cells are found narrow in the middle and wider at the ends.

Hence, the correct answer is option (4) "5".
