B. Sclereids(ii) Main water conductive cells of the pteridophytes and the gymnosperms
C. Tracheids(iii) Thick walled, elongated and pointed cells, generally occurring in groups

B. A - (iii), B - (v), C - (ii), D - (iv), E - (i)

C. A - (iii), B - (i), C - (v), D - (ii), E - (iv)

Correct Answer :

B. A - (iii), B - (v), C - (ii), D - (iv), E - (i)


A - Fibres: Fibres are thick walled, elongated and pointed cells, generally occurring in groups, in various parts of the plants.
B - Sclereids: Sclereids is a thick-walled lignified sclerenchyma cell. Sclereids are variable in shape and are shorter than fibres.
C - Tracheids: Tracheids are the more ancient tracheary 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 (pteridiophytes), pitted or bordered-pitted (gymnosperms) thickening. Water moves from cell to cell through the side walls.
D - Vessels: Vessel is a long cylindrical tube like structure made up of many cells called vessels members.
E - Xylem parenchyma: Xylem parenchyma 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.
