| A. | Fibres | I. | Cells are living and thin walled with cellulosic cell wall, store food materials in the form of starch or fat. |

D) A - V; B - IV; C - III; D - I; E - II
Correct Answer: B
Solution :
| [b] A - Fibres: These are thick walled, elongated and pointed cells, generally occurring in groups, in various parts of the plants. |
| B - Sclereids: These are thick-walled lignified sclerenchyma cell. Sclereids are variable in shape and are shorter than fibres. |
| C - Tracheids: These are the more ancient treachery elements, the main water conductive cells of the pteridophytes and the gymnosperms. They are elongate cells with tapering ends. Their cell walls characteristically bear spiral (pteridophytes), I pitted or bordered-pitted (gymnosperms) thickening. Water moves from cell to cell through the side walls. |
| D - Vessels: It is a long cylindrical tube like structure made up of many cells called vessels members. |
| E - Xylem parenchyma: These cells are living and thin walled and their cell walls are made up of cellulose. They store food materials in the form of starch or fats and other substances like tannins. |
