Indicate the statement which is not correct?
1 Stem tuber of potato, rhizome of Zinziber and corm of Colacasia help in perennation to tide over unfavorable conditions for growth.
2 Roots of Taeniophyllum and Avicennia called pneumatophores, help to get oxygen for respiration
3 The haustorial roots of Striga and Cuscuta help to obtain water and minerals from the host plant
4 Rhizobium inhabit the root system to fix atmospheric nitrogen by forming nodules, nodular root in Pisum, Cajanus, Cassia, etc
Explanation:
B Roots Taeniophyllum and Avicennia called preumatophores, help to get oxygen for respiration is incorrect statement because pneumatophores, commonly found in mangrove species that grow in brackish soil plants have lateral roots that grow upward to act as sites of oxygen intake for the submerged primary root system.

Roots of the following hydrophytes are fixed to substratum, but their long petiolated leaves keep them floating on water surface (i) Salvinia (ii) Victoria regia (iii) Utricularia (iv) Nymphaea The correct combination is
1 i \& ii
2 ii \& iii
3 iii \& i
4 ii \& iv
Explanation:
D Hydrophytes are aquatic plants that grow only in water. Free floating hydrophytes are the plants that remain floating on the surface of water but in some species the roots remain embedded in the mud and only some parts on the plant like flowers and leaves float on water. e.g:- Victoria regia, Nymphaea, Salvinia etc.
