There are certain levels which form the basis of classification of tissues present in plants and animals:
● On the basis of movement - Plants are stationary and they do not move while animals move from one place to another for various reasons. Therefore, the tissues required by plants are those which provide mechanical strength and mostly they are dead in nature whereas in animals the tissues are living as they need to move.
● On the basis of the pattern of growth - The growth pattern of plants and animals also differs. Plants have certain regions which continue to divide throughout the life while the same thing does not happen in case of some other regions. There is more uniform cell growth in animals as compared to plants.
So, tissues are classified considering the pattern of growth.
● On the basis of the structural organization - The structural organization of animals is far more complex as compared to plants. Therefore, there are differences in tissues which are responsible for the structural organization and form a basis of classification.
