Ecological Adaptations of Xerophytes (with PPT)
What are xerophytes? Ø Xerophytes (xerophytic plants) are plants growing in dry habitats (xeric conditions) where the availability of water is very less. Xeric habitat are the places where water is NOT present in adequate quantity. Xerophytes are the characteristic plants of deserts or semi-deserts areas. Xerophytes can also grow in mesophytic conditions. The present post […]

Physical and Chemical Properties of Water and its Biological Significance
Physical and Chemical Properties of Water: Water is the most abundant substance in the living system. Water makes up about 70% or more of the weight of almost all organisms. The life has originated in remote past in the aqueous environment. The properties (both physical and chemical) of water enabled it as the ‘solvent of […]

Ecological Adaptations of Hydrophytes (with PPT)
What is adaptation? “Any feature of an organism which enables it to exist under conditions of its habitat is called adaptation”. Adaptations are for withstanding adverse conditions of environment and to utilize the maximum benefit of the environment (nutrition or conditions). Adaptations in plants can be of four types: 1. Morphological features 2. […]
