cell specialization tissue

A group of cells of the same type or of a mixed type having a common origin and performing similar functions are called tissues..

These tissues are derived from meristematic tissues. They have lost the power of dividing, having attained their definite form and size. In their earlier stages the cells are more or less similar in structure but slowly they become specialized and form perman..

Nature, Occurrence and Function..

It is represented by loosely arranged parenchyma cells found in between the vascular bundles. The cells are specialized for storage of wate..

Bone This is a connective tissue in which the ground substance or matrix is composed of elastin, which is impregnated with salts of calcium and magnesium. Skeletal tissue is of two kinds, bone and cartilage. Cartilage is softer than bone and does not contain the organic salt..

Permanent Tissues - Permanent tissues are derived from meristematic tissues. They have lost the power of dividing, having attained their definite form and size. In their earlier stages the cells are more or less similar in structure but slowly they become ..

Areolar tissues This consists of tendons and ligaments. Tendons are strong inelastic and connect muscles to bones. Ligaments are elastic and connect bones to each other. This tissue has a matrix in which are scattered special cells, which can engulf bacte..

Muscular Tissue - The muscular tissue is a tissue that is capable of bringing about different types of movements in the body. It is one of the highly specialized animal tissues. It is a derivative of mesoderm. The muscular tissue exhibits ..

Simple epithelium may sometimes become modified for some specific functions. Two such modifications are very common, namely, ciliated epithelium and glandular epithelium. Ciliated epithelium is always a modification of columnar epithelium. Here, the cells are characterized by the presence..

The permanent tissues are formed by the differentiated cells, which become specialised to perform specific functions like protection, support, storage and conduction. The permanent tissues always differentiate from the meristematic cells, during the process o..
