|
|
Cell wall thickened at the corners with cellulose
|
|
|
Evenly thickened cell walls with lignin
|
|
|
Thin cell wall with large vacuoles
|
Detailed explanation-1: -Due to the hemicellulose, cellulose, and pectin deposits, the cells of collenchyma tissue are significantly thickened at the corners. Elongated cells with unevenly thickened walls make up collenchyma tissue. They offer structural support, particularly to leaves and budding shoots.
Detailed explanation-2: -Collenchyma tissue possesses elongated cells with irregular thickening, mainly at the corners. They possess only thick primary cell wall made of cellulose and pectin.
Detailed explanation-3: -Collenchyma tissue is composed by elongated living cells of uneven primary thick walls, which possess hemicellulose, cellulose, and pectic materials. It provides support, structure, mechanical strength, and flexibility to the petiole, leaf veins, and stem of young plants, allowing for easy bending without breakage.
Detailed explanation-4: -Cells of collenchyma are thickened with pectin, while cells of schlerenchyma are thickened with lignin.
Detailed explanation-5: -Pectin and cellulose are deposited at the corner of cells in collenchyma.
