A living mechanical tissue having cellulosic wall thickening is
Open in App
Solution
The correct option is B Collenchyma
Collenchyma tissue is composed of elongated cells with irregularly thickened walls. They provide structural support, particularly in growing shoots and leaves. Collenchyma tissue makes up things such as the resilient strands in stalks of celery. Collenchyma cells are usually living, and have only a thick primary cell wall made up of cellulose and pectin. Cell wall thickness is strongly affected by mechanical stress upon the plant. So, the correct answer is 'Collenchyma.'
