Detailed explanation-1: -water, temperature and plant growth regulators.
Detailed explanation-2: -The important factors affecting the growth of plants include: Temperature: Growth is accelerated with the increase in temperature. Light: Light intensity, duration of light and the quality of light influence many physiological processes occurring in a plant. Water: Water is an essential factor for plant growth.
Detailed explanation-3: -Solution: Plant growth regulators are intercellular intrinsic factors that influence the development of a plant. DNA and chlorophyll are intracellular intrinsic factors. Mineral nutrients are extrinsic factors that influence the development of plant.
Detailed explanation-4: -Intrinsic factors include the genetic, physiological, and pathological characteristics of an individual; in other words, these are traits that are “intrinsic” to a person rather than being determined by that person’s environment.
Detailed explanation-5: -The genotype of a plant affects its growth. For example, selected varieties of rice grow rapidly, maturing within 110 days, whereas others, in the same environmental conditions, grow more slowly and mature within 155 days. A producer has control over the genetic factor by his choice of variety.
