Question

Match the items in column I with those in column II, and select the correct option.
$\begin{array}{cc}\text{Column I}& \text{Column II}\\ \text{(p) Food storage}& \text{(i) Collenchyma}\\ \text{(q) Irregular cell wall}& \text{(ii) Meristematic tissues}\\ \text{thickening}& \\ \text{(r) Mechanical strength}& \text{(iii) Parenchyma}\\ \text{(s) Increases girth of plant}& \text{(iv) Scerenchyma}\end{array}$

Answer 1

Meristematic tissues are small, cuboidal, densely packed cells that keep dividing to form new cells. Parenchymatous tissues help in storage and photosynthesis.
They also help the plant to float on water. Collenchymatous tissues provide mechanical support to the plant structure in parts such as the petiole of the leaf.
Sclerenchymatous tissues provide strength and support to various parts of the plant.
