Detailed explanation-1: -2.2 Collenchyma Tissue. Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials.
Detailed explanation-2: -Collenchyma walls have a similar composition to primary cell walls (Jarvis, 1992). These cell walls surround growing cells and are made up of cellulose microfibrils embedded in a hydrated matrix of complex polysaccharides classified as hemicelluloses and pectins (Cosgrove, 2005).
Detailed explanation-3: -Final answer: The chloroplasts containing simple tissues showing thickening at the corners with cellulose, hemicellulose, and pectin are collenchyma. Q. Q.
Detailed explanation-4: -The plant cell wall predominantly consists of pectin, hemicellulose and cellulose.
Detailed explanation-5: -So, the correct answer is ‘Cell wall of parenchyma is made of pectin.
