Exp:B : Fibre elongated end wall tapering lignified lumen empty. - Cotton thread fibres obtained from Gossypium arboreum and G. herbaceum found in seed surface. - Cotton fibers are natural hollow fibers: They are soft, Cool, Known of breathable fibers and absorbent.

Two cross-sections of stem and root appear simple, when viewed by naked eye. But under microscope the can be differentiated by
1 exarch condition of root and stem
2 endarch condition of stem and root
3 endarch condition of root and exarch condition of stem
4 endarch condition of stem and exarch condition of root
Explanation:
Exp:D In endarch condition when Protoxylem lies towards the centre and metaxylem towards the pheriphery the condition of xylem is called endarch as stem. - Exarch When protoxylem lies towards pheriphery and metaxylem towards the centre condition is called exarch as root.
Exp:D Endodermis:- This is uniseriate layer of cells delimiting the cortex from stole. It consists of barrel shaped cells arranged quite close to each other having no inter cellular spaces amoung them. The cells are endodermis and elongated and arranged parallel to the long axis of the vascular tissue. Function of endodermis:- There is great controversy about the function of the endodermis storage of starch grain. Cortex generally is present in dicot stem, ground stem, and monocot stem. Cortex in the root, Extends from hypodermis to the endodermis, multilayered thin walled parenchymatous living cells.

For a successful graft, the adhesion between the scion and stock is essential. In your view which of the following is the earliest event towards a good graft?
1 Production of plasmodesmata in the cells at the interface of scion and stock
2 Co-ordinated differentiation of vascular tissue between the stock and scion
3 Regeneration of cortex and epidermis over the union of stock and scion
4 Production of callus tissue between the cells of scion and stock
Explanation:
Exp:B For a successful grafting the adhesion between the scion and stock is essential.Stock is a rooted stem in to which a scion orbed is grafted and the portion of the mixture provides the root. Scion is living plant component that is detached and grafted to the stalk during the grafting process.
