One of the following is not true for hydrophytes.
1 Vessels are usually absent
2 Tracheids are absent
3 Cuticle is poorly developed
4 Air chambers are well developed
Explanation:
Exp:B Tracheids are absent is not true for the hydrophytes. In hydrophytes cuticle is poorly developed. It have special air chambers called 'aerenchyma'. Tracheids are developed but the vessels are completely absent in hydrophytes.

Medullary rays are made up of
1 parenchymatous cells
2 sclerenchymatous cells
3 tracheids
4 fibres
Explanation:
Exp:A Medullary rays are made up of 'parenchymatous cell. Medullary rays are also known as vascular rays or pith rays. These rays are parenchymatous cells which allow the radial transport of sap and essential in the process of tylosis. Medullary rays store and transport food material.

Growth rings are formed due to activity of :
1 extrastelar cambium
2 intrastelar cambium
3 interstelar cambium
4 both 'a' and 'c'
Explanation:
Exp:B Growth rings are formed due to the activity of intrastelar cambium. These rings are found in trees. The growth occurs in the cambium which creates new tissue and increases the growth of the tree. Cambium is responsible for the annual or growth ring. Intrastelar cambium is present between xylem and phloem in dicot stem and roots. The vascular cambium is present within the stele, therefore it is also termed as intra-stellar cambium (vascular cambium) is responsible for increasing the diameter of stems and roots and for producing woody tissue.

Cotton fibres which are obtained from Gossypium are:
1 surface fibre
2 soft fibre
3 hard fibre
4 bast fibre
Explanation:
Exp:A Cotton fibres are surface fibre which are obtained from Gossypium, extracted from the covering of seed. They grow from the surface of seeds, leaves or fruits. The surface fibre is made of pure cellulose.

The longest plant cell is :
1 fibre
2 vessel
3 tracheid
4 sieve tube
Explanation:
Exp:A The longest plant cell is fibre. Fibres are greatly elongated cells whose long, tapering ends interlock, which provides maximum support to a plant fibres are the longest plant cells with the length up to 21.65 inches long. It is elongated by intercalary growth and intrusive tip growth.
