Does the storage size depend on the flexibility of the cell wall? A parenchymatous tissue modifies into three major types, namely chlorenchyma, aerenchyma and prosenchyma. It was introduced in the 17th century when Robert Hooke discovered the plant cells. Perform most of the metabolic function so the plant. A ground tissue of plants chiefly concerned with the manufacture and storage of food. @.

Collenchyma tissue with chloroplasts. [4] However, it often includes any form of lung tissue, also including bronchioles, bronchi, blood vessels and lung interstitium. Definition of Parenchyma tissue It can define as the simple permanent tissue, which is usually thin-walled and functions as a “ ground tissue ” by forming a packaging material of all the non-woody structures like leaves, roots and stems. The parenchymal cells include myocytes, and many types of specialised cells. When you eat leafy greens, which type of cells would you be eating mostly? It refers to the cells that perform the biological function of the organ , such as the lung cells that perform the gas exchange, the liver cells that cleanse the blood or the brain cells that perform the functions of the brain for their good performance. Ø They are living cells with prominent nucleus and all the cell organelles. This is a spongy tissue also known as a mesenchymal tissue, in which several types of cells are lodged in their extracellular matrices. Types of Parenchymatous Tissue. Ø  In circular parenchyma, the cells are circular (round) in outline. Plants must be able to do photosynthesis in order to create energy and survive. Repair of wounds.
