They store the food and provide turgidity to softer parts of plant. They are found in non-woody and soft areas of stem, root, leaves, fruits and flowers. Each cell encloses a large central vacuole and peripheral cytoplasm containing nucleus.

Parenchyma is a simple permanent living tissue which is made up of thin-walled isodiametric cells.

Permanent tissues having all cells similar in structure and function are called simple permanent tissues and those having different kinds of cells are called complex tissue.

The cells that have become structurally and functionally specialized and lose the ability to divide are called permanent tissue.Vascular cambium, cork cambium are secondary meristem. Intrafascicular cambium in the primary lateral meristem.

The meristem which occurs on the sides and takes part in increasing girth of the plants are called Lateral meristem.Intercalary meristem occurs between mature tissues especially in grasses.Both apical meristems and intercalary meristems are primary meristems because they appear early in life of a plant and help to form the primary plant body.The meristem which occurs at tips of roots and shoots are called apical meristem. Meristematic tissue is a simple tissue composed of group of similar and immature cells which can divide and form new cells.The tissueĪ group of cells having a common origin and usually performing common function are called tissues. Anatomy helps in knowing the structural peculiarities of different group of plants and indicates the structural adaptation to diverse environments. Study of plant anatomy includes histology- study of organization and structure of tissues.
