why living cell in plant possess thin cell wall?
Parenchyma is the most common and versatile ground tissue: it forms the cortex and pith of stems, the cortex of roots, the mesophyll of leaves, the pulp of fruits, and the endospermof seeds. Parenchyma cells are living cells, and may still be able to divide when they are mature. Because of this, parenchyma cells are important for regeneration and wound healing. They have thin but flexible cell walls because the secondary cell wall is usually absent. Photosynthesis usually occurs in parenchyma cells (the mesophyll), and they function in the storage of carbohydrates. They are generally polygonal when packed close together, but are nearly spherical when separated from their neighbours. They have large central vacuoles which allow the cells to store and regulate ions, waste products and water.
