The plant tissue having aquatic adaptation is
1 collenchyma
2 sclerenchyma
3 aerenchyma
4 parenchyma
Explanation:
Exp:C The adaptations can be easily observed in the anatomy of the hydrophytes. Aerenchyma is specialized parenchyma cells which are air -filled. They provide buoyancy to the aquatic plants. In the cross-section of aquatic plants aerenchyma appears like a cavity. Each cavity is separated from one another using chlorenchymatous cells. Some characteristics of parenchyma are as follows. The arenchyma is filled with respiratory gases like carbon dioxide, oxygen. The air chambers have the presence of cross septa called as the diaphragm which provides better aeration and is important in plant floating.

Oval, spherical or polygonal cells, thickening at the corners due to the deposition of cellulose, hemicellulose and pectin, often containing chloroplasts and having or not having intercellular spaces are called
1 parenchyma
2 chlorenchyma
3 sclerenchyma
4 collenchyma
Explanation:
Exp:D Oval, spherical or polygonal cells, thickening at the corners due to the deposition of cellulose, hemicelluloses and pectin often containing chloroplasts and having or not having intercellular spaces are called 'Collenchymatous cells. The cells of collenchymas tissue may also usually be oval, round or virtually usually polygonal and often type of basically comprise chloroplasts in a genuinely most important way in an especially huge way. It consists of cells which are much thickened at the corners due to the deposition of cellulose, pectin and the hemicellulose. Intercellular spaces are absent in collenchyma tissue.

Vessels and companion cells are characteristics of :
1 angiosperm
2 gymnosperm
3 pteridophyta
4 fern
Explanation:
Exp:A Vessels and companion cells are characteristics of 'angiosperm'. It is one of the important features of flowering plants and around the plant it carries water. Water transport is maintained by the xylem part of angiosperms and transport of food is maintained by the phloem part. Companion cells are the integral component of the phloem in the angiosperms. It is closely associated with the development and function of a sieve-tube element. Hence, vessels and companion cells are the characteristic features of angiosperms and absent in gymnosperms, pteridophytes, and bryophytes.

Radial conduction of water takes place by
1 vessels
2 vessels and tracheids
3 phloem
4 ray parenchymatous cells
Explanation:
Exp:D Radial conduction of water takes place by 'ray parenchymatous cells'. Transport of nutrients and water radially between the xylem and phloem by ray parenchyma cell. Radial conduction refers to the conduction of water in the horizontal direction through the xylem. Hence, radial conduction takes place by the ray parencymatous cells of xylem.
