The waxy substance associated with cell wall of cork cells is :
1 suberin
2 cutin
3 hemicelluloses
4 lignin
Explanation:
Exp:A The waxy substance associated with cell wall of cork cell is 'Suberin'. Suberin is highly hydrophobic and its main function is to prevent water from penetrating the tissue.

1 Parenchyma
2 chlorenchyma
3 collenchyma
4 sclerenchyma
Explanation:
Exp:C A tissue whose living cells form the mechanical tissue of activity growing organs and whose cell walls shows cellulosic unlignified thickenings often at the corners of its cells is called 'collenchyma'. Term Collenchyma coined by Schleiden. It is a living mechanical tissue.

Excessive aerenchyma is characteristic of :
1 heliophytes
2 mesophytes
3 xerophytes
4 hydrophytes
Explanation:
Exp:D Excessive Aerenchyma is characteristic of 'hydrophytes' in aquatic plants (hydrophytes) have large air cavities present in Aerenchyma to give support them to float on water. Hydrophytes possess special air storage parenchyma tissue, called as Aerenchyma. For example:- Hydrilla, Ceratophyllum, Lotus, Echhornia etc.

Collenchyma resembles parenchyma in being
1 potentially meristematic
2 partially cutinised
3 provided with air spaces
4 devoid of chloroplasts
Explanation:
Exp:D Collenchyma resembles parenchyma is being devoid of chloroplasts. Parenchyma cells containing chloroplasts which is called chlorenchyma. Collenchyma cell may or may not contain a few chloroplasts. Hence, collenchyma is a correct answer.

Which of the following would be insignificant} amount in xylem sap?
1 Sugar
2 Nitrates
3 Phosphates
4 Water
Explanation:
Exp:A 'Sugar', would be insignificant amount in xylem sap. Xylem is a vascular tissue which has the role of the conduction of water and minerals form the roots to the shoots in the plants. It is found in roots, stems and leaves of the plants. Phloem is the tissue of the plant which transports the soluble organic substances to the various parts of the plant. Sugar is carried by the phloem form the leaves to the other parts. Phloem tissue is involved in transport of sugar.
