A) xerophytes
B) mesophytes
C) lithophytes
D) hydrophytes
Correct Answer: A
Solution :
The plants developing in dry conditions are called xerophytes. It is difficult to decide whether a xerophyte is really xerophilous and occur only in dry habitats or deserts or is merely drought-resistant. The xerophytes have well developed root-system, stunted, woody, hard stem and reduced leaves. The hydrophytes grow on extremly wet soil where water is available to plants in abundance. They may be free floating, submerged, or rooted emergent. The root is either absent or poorly developed. Mesophytes are such land plants which grow in moist habitats and need well-aerated soils. They prefer soil and air of moderate humidity and avoid soil with standing water or containing a great abundance of salts. The plants which grow on rocks are called lithophytes.
