NCERT Solution: The Living World
A plant species shows several morphological variations in response to altitudinal gradient. When grown under similar conditions of growth, the morphological variations disappear and all the variants have common morphology. What are these variants called?
NCERT Exampler
These variants are called biotypes. All biotypes are similar genetically but they are different morphologically. The morphological difference happens because of the differences in abiotic factors like temperature, pH of soil, climate etc. The difference in abiotic factors is the result of different altitudinal gradients.
