    Sea plants are an example of :

    A)  xerophyte     

    B)  mesophyte

    C)  hydrophyte    

    D)  submerged plant

    Correct Answer: C

    Solution :

    The hydrophytes grow on extremely wet soil where water is available to plants in abundance. Sub-merged plants are those hydrophytes which remain completely submerged in water and not rooted in mud, or remain completely submerged in water and rooted in soil. Mesophytes are such plants which grow in moist habitats and need well- aerated soil. They prefer soil and air of moderate humidity. These generally lack the special structural and physiological adaptations found in hydrophytes and xerophytes. Xerophytes grow in water deficient soil. Root system is well-developed in these plants and these are variously adapted to dry habitats.
