Stereoisomers:Enantiomers and Diastereomers

Stereoisomers are further divided into two types. They are
1) Enantiomers
2)Diastereomers

Enantiomers:

These are the isomers which are mirror images and non-superimposable are called  Enantiomers.
These are also called as optical isomers.
Ex.(+)Menthol and (-)Menthol.

Diastereomers:

These isomers are non-mirror images and non-superimposable are called Diastereomers.

Types of stomata

Image
Types of Stomata:  On the basis of size, shape, number and and arrangement of Subsidiary cells stomata are classified into six types. Metcalf and Chalk defferentiated various types of stomata. A. Anamocytic: Guard cells are surrounded by 4 or more subsidiary cells which are similar in size and shape. Two subsidiary cells are present in bothpolar regions of guard cells and the remaining two are present on two lateral sides. Ex: Rananculaceae, Papaveraceae, Tridax procumbans. B. Anisocytic: Guard cells are surrounded by 3 subsidiary cells and are differ in size. Two subsidiary cells are bigger in size at lateral sides and one cell in smaller in size at one polar region of guard cells. Ex: Cruciferae, Umbilliferae, Datura. C. Paracytic: Guard cells are surrounded by two large subsidiary cells which are similar in size and are present at the two lateral sides of the guard cells. Ex: Rubiaceae, Magnoliaceae, Ixora. D. Diacytic: Guard cells are surrounded by two large subsidiary cells wh...
