NEET BIOLOGY

Detailed explanation-1: -Environmental factors that affect plant growth include light, temperature, water, humidity and nutrition.

Detailed explanation-2: -Flooding often leads to oxygen deprivation in soils and plant roots, which significantly restricts metabolic activities for plant survival and development. Therefore, amounts of aerenchyma and ROL barriers in plant roots are formed to transport adequate oxygen from shoots to roots (Figure 1C).

Detailed explanation-3: -They are water, light, nutrients, and temperature. These four things affect the growth hormones of the plant, which will either make the plant grow quickly or slowly. Making changes to any of these four things can cause stress to the plant, which in turn can change or stunt the growth or improve the growth.

Detailed explanation-4: -Light, water, temperature, humidity, ventilation, fertilization, and soil are chief factors affecting plant growth, and any one of these factors in incorrect proportions will prevent proper plant growth indoors. Light is probably the most essential factor for house plant growth.
