Cells of tissue A have small intercellular spaces and walls thickened at the corners. Cells of tissue B do not have intercellular spaces and thickened cell walls. Identify tissue A and B.

Q. The cells of tissue A have small intercellular spaces, and their walls are thickened at the corners. The cells of tissue B do not have intercellular spaces, and the cell walls are thickened. Identify tissues A and B.

Q.

Cells of this tissue are living and show angular wall thickening. They also provide mechanical support. The tissue is

(a) xylem

(b) sclerenchyma

(c) collenchyma

(d) epidermis

Q. The sclerenchyma tissues have thickened cell walls.

Q. Sclerenchyma tissues have no intercellular space as the walls are thickened due to the presence of __________________. What is lignin?

Q. Arrange the following type of tissues on the basis of intercellular spaces between them in decreasing order:
Parenchyma, collenchyma, sclerenchyma
