What are Paracytic stomata?
paracytic (meaning parallel celled) stomata have one or more subsidiary cells parallel to the opening between the guard cells. These subsidiary cells may reach beyond the guard cells or not. This type of stomata can be found in more than hundred dicot families such as Rubiaceae, Convolvulaceae and Fabaceae.

Which of the following are examples of Anisocytic stomata?
Anisocytic stoma remains surrounded by three unequally sized subsidiary cells, among which one is distinctly smaller in size than the other two. Ex. Cruciferae, Solanum, Petunia, Sedum and Nicotiana etc. Metcalfe and Chalk mentioned 37 families where anisocytic stoma occurs.
What is difference between Paracytic and Diacytic stomata?
-Diacytic stomata-These are surrounded by a pair of subsidiary cells perpendicular to the cells that are covered. -Paracytic Stomata: There are two subsidiary cells surrounding them. -Gramineous Stomata: There are two guard cells in each stoma. The pair of subsidiary cells surround diacytic stomata.

What is the difference between stoma and stomata?
stomate, also called stoma, plural stomata or stomas, any of the microscopic openings or pores in the epidermis of leaves and young stems. Stomata are generally more numerous on the underside of leaves.

What are Anomocytic stomata?
Anomocytic. Refers to stomata that lack subsidiary cells. Paracytic. Refers to stomata that possess one or more pairs of lateral subsidiary cells oriented parallel with the guard cells.

What do you mean by Anomocytic stomata?
Anisocytic Stomata
This type of stomata has three subsidiary cells, unequal in size, where one cell is smaller than the other two. These subsidiary cells do not have a specific layout of presence, but the number is fixed. They are also known as the unequal-celled type or cruciferous stomata.
Which stomata is found in Senna and coca leaves?
Paracytic
2. Gymnospermous type stomata are found in naked seeded plants. They have sunken stomata to reduce transpirational water loss.

Which type of stomata are present on the epidermis of pericarp in fennel?
The fruit of Calotropis is called exostomatic as the stomata are present only on the outer layer of epi or exocarp. Metcalfe and Chalk (1950) recorded paracytic type of stomata on the foliar epidermis of C. procera. On the pericarp we have observed only the perigenous type of stomata.
Which stomata is present in Datura?
The stomata are absent on the outer epidermis of their pericarp. The inner epidermis of the pericarp has anomocytic stomata. The contiguous stomata are common. There are 4–6 surrounding cells with each stomata.
What are the 3 functions of stomata?
– It helps in removing water from the leaves. – It takes carbon dioxide and gives out oxygen during the process of photosynthesis. – It helps in regulating water movement through transpiration. Stomata facilitates gaseous exchange.

In this type stoma remains surrounded by three accessory or subsidiary cells of which one is distinctly smaller than the other two.
Which type of stomata are seen in fennel?
In Foeniculum vulgare, the adaxial and abaxial stomata were observed to be opened which implies that the rate of transpiration is high in this plant.

What is the importance of stomata?
Stomata regulate gas exchange between the plant and environment and control of water loss by changing the size of the stomatal pore.
