1.	Question : Differentiate between Meristematic and permanent tissues .
Answer» Solution :The cells of meristematic tissue are thin-walled, mostly isodiametric and are compactly arranged without any intercellular spaces. They take a deep stain and have larger nuclei. They have dense cytoplasm either with very small vacuoles or without any vacuole. The protoplast of meristematic cells is devoid of reserve food MATERIALS and PLASTIDS and it has poorly developed ENDOPLASMIC reticulum. On the contrary, permanent tissues are formed as the result of division and differentiation in meristematic tissues. These tissues are composed of cells which have lost the power of division, having ATTAINED their definite form, SIZE and shape. The cells of permanent tissues maybe living or dead and thin or thick-walled.
