There are five type of connective tissues: (i) Areolar connective tissue: It is a loose and cellular connective tissue. As a result, they form a permanent tissue. Neurons are highly specialized for being stimulated and then transmitting the stimulus very rapidly from one place to another within the body. This is because since the root tips are cut, the roots won’t grow because of absence of meristematic tissue. 1. The cells of parenchyma assimilate and store food.

Permanent tissue are classified into the following two types: (i) Simple permanent tissue (ii) Complex permanent tissue Simple permanent tissues: These tissues are composed of cells which are structurally and functionally similar. This happen because of transpiration due to which water is released from the plant in the form of water vapour which appears on the glass jar. Plants are autotrophic organisms, so they prepare their own food by photosynthesis. This forms the several layer thick cork or the bark of the tree. In brief, chlorenchyma and aerenchyma are two types of parenchyma tissues that carry out specific functions in plants. As plants grow older a strip of secondary meristem replace the epidermis of the stem. Due to this, plant can survive in scarcity of water in desert.
