Answer 2

Answer:

In collenchyma the thickening of corners is made of deposition of cellulose, hemicellulose, and pectin.

Explanation:

• In collenchyma the thickening of corners is made of deposition of cellulose, hemicellulose, and pectin.
• Collenchyma is called as supporting tissue which is composed of more or less elongated living cells with unevenly thickened, and nonlignified primary walls.
• The collenchyma is found below the epidermis of dicotyledonous plants and do not have any intracellular spaces.
• It found either  in patches which consists of cells that are very thick in corners because of deposition of cellulose,hemicellulose and pectin or as a homogeneous layer below the epedermis.
• Collenchyma is a living tissue which have cellulose and water inside that help plant to maintain its shape.
• Collenchyma protect the plant against any mechanical injury, work as sheath that regulates wtaer flow and prohide support for vascular tissue.
