Match the column (A) with the column (B)

Column 1	Column 2
Parenchyma.	Thin walled, packing cells.
Photosynthesis.	Carbon fixation.
Aerenchyma.	Localized thickening.
Collenchyma.	Buoyancy.
Permanent tissue.	Sclerenchyma.

(a) Parenchyma (i) Thin-walled, packing cells.

1. Parenchyma is thin-walled, unspecialized cells that form the ground tissue in plants.
2. They are tightly packed cells that are multifunctional in nature such as storage, photosynthesis, structure, etc.

(b) Photosynthesis (ii) Carbon fixation

1. Photosynthesis is a light-dependent energy-producing reaction that fixes atmospheric carbon to produce sugars such as glucose.
2. The raw materials for photosynthesis are sunlight, water, and carbon dioxide which create oxygen and energy in the form of sugar,

(c) Aerenchyma (iv) Buoyancy

1. Aerenchyma cells are air containing parenchyma cells found in certain aquatic plants
2. They are air-filled cells that give the plants buoyancy and keep them afloat.

(d) Collenchyma (iii) Localized thickening

1. Collenchyma is a simple permanent tissue with extra cellulose compared to parenchyma cells.
2. Collenchyma cells provide thickening in the corner cells and fives flexibility to plant parts.

(e) Permanent tissue (v) Sclerenchyma

1. Sclerenchyma is a type of hard permanent tissue that is thick-walled.
2. Sclerenchyma cells at maturity lose their ability to divide and form permanent tissues.
