Both lysosomes and vacuoles are endomembrane structures, yet they differ in terms of their functions. Comment.

All the body cells are of same origin and therefore, have same genes, yet they differ in structure and function because they synthesize different

We are structurally different but functionally similar. Who are we?

Name the organs which are same in their structure and performing different functions.

Organs that are common in embryonic origin and have the same fundamental structure but perform different functions are called

The eye of octopus and eye of cat show different patterns of of structure , yet they peform similar . This is an example of :

Write your opinion on evolutionary evidences of the following information . In all the animals forelimbs are structurally similary but perform different functions according to the habitat in which they live.

Compounds having the same molecular formula, same structure with different configuration are called stereoisomers and the phenomenon is called stereoisomerism. The phenomenon is broadly classified with three types called (a) geometrical isomerism (b) optical isomerism and (c) conformational isomerism. Which of the following compounds exhibit both geometrical as well as optical isomerism

Structural isomers have different covalent linkage of atoms. Stereoisomers are compounds that have same sequence of covalent bonds but differ in the relative dispositions of their atoms in space. Geometri cal and optical isomers are the two important types of configurational isomers. The compound with double bonds or ring structure have restricted rotation, so exist in two geometrical forms. The double bonds in larger rings (ring size 10 carbon large) can also cause geometrical isomerism. The optical isomers rotate the plane of plane-polarised light. A sp^(3) -hybridised carbon atom bearing four different types of substituents is called an asymmetric centre or chiral centre. A chiral object or molecule cannot be superimposed on its mirror image. Stereoisomers that are mirror images of each other are called enantiomers. The stereosomers that the pot mirror images of each other are called diastereomers. Diasteremers have different physical properties. A racemic mixture is optically inactive and contains equal amounts of both the enantiomers. Resolution refers to method of separating a racemic mixture. Into two pure enantiomers. A meso compound is an optically inactive stereoisomer, which is achiral due to the presence of an internal plane of symmetry or centre of symmetry within the molecule. The number of chiral centres present in the following compounds is
