Assertion (A): Lateral (or cambium) meristem is responsible for the increase in the girth (diameter) of the stem.
Reason (R): Cambium is located near the tips of the root and stem and also on the tips of axillary buds where growth occurs at a faster rate.

Answer
A is True and R is False.
Reason — The lateral meristem is responsible for secondary growth, i.e., the increase in girth of stems and roots.
Apical meristem is found at the tips of roots, stems, and axillary buds, and it contributes to length-wise growth.

Deepali tried to match the kind of supporting tissues in plants with their characteristic features.
She tabulated the pairs as follows:Supporting tissue Cellular structure P Dead cells, have thick walls due to deposition of lignin Q Elongated cells, cell wall is thickened at the corners Identify P and Q
- P — Collenchyma, Q — Sclerenchyma
- P — Sclerenchyma, Q — Collenchyma
- P — Parenchyma, Q — Sclerenchyma
- P — Collenchyma, Q — Parenchyma
Assertion (A): Collenchyma is composed of long and narrow cells. These cells have very thick walls due to the deposition of lignin.
Reason (R): Collenchyma stores food and provides temporary support to the parts of a plant.
