Biology Today - February 2018

In a complex multicellular organism, all functions like digestion, respiration, reproduction, etc., are carried out by different groups
of cells arranged in a well organised manner. Such a group of similar cells along with intercellular substances having similar origin
and performing a specific function, constitute tissue.

The study of tissues is called histology (Mayer, 1819).

The syllabus for NEET is very vast which impedes students from

acquiring indepth knowledge and covering the entire syllabus

at the same time. An essential topic for NEET is therefore

presented here to enable students grasp the topic, analyse the

type of questions and SCORE HIGH.
