Answer:
Soil physical condition, pH and climatic condition
Step-by-step explanation:
The following environmental condition affects the growth of roots of plant –
a) Soil physical condition – If soil is extremely wet or dry, the roots of the plant do not grow efficiently and remain underdeveloped.
b) Soil pH condition – The soil can grow in optimum pH condition. If the soil is extremely acidic or alkaline the plants will not be able to take up the essential nutrients from the soil.
c) Extreme cold or heat climatic condition, the growth rate of plant will become slow and hence the roots do not develop to their full length.
