Answer

The basic differences between meristematic and permanent tissues of plants are tabulated below

Meristematic tissue	Permanent tissue
1	Its component cells are living, small, spherical or polygonal and un-differentiated	Its components cells may be living or dead. They are large, differentiated with different shapes.
2	Cytoplasm is dense and vacuoles are nearly absent as they are metabolically active.	Large central vacuole occurs in living permanent cells as, they are less metabolically active.
3	Intercellular spaces are absent.	Intercellular spaces are often present.
4	Cell wall of its cells is thin and elastic.	Cell wall of its cells may either thin or thick.
5	Nucleus of each cell of this tissue is large and prominent.	Nucleus is less conspicuous.
6	Its cells grow and divide regularly.	Its cells do not normally divide.
7	It is a simple tissue.	It can be simple, complex or specialized,
8	Cell organelles of its cells are simple	Cell organelles of its cells are well developed.
9	Cell contain crystals and other inclusions.	Cells crystals and other inclusions
10	It provides growth to the plant.	It provides protection. Support, conduction photosynthesis, storage, etc.

Cells derived from the division of meristematic tissues take up specific roles and gradually lose their ability to divide. Thus, they form permanent tissue. Differentiation is a process by which the cells divide meristematically to take a permanent shape, size and function

Parenchyma and collenchyma are two simple permanent tissues whereas xylem and phloem are two complex permanent tissues.
