RESEARCH METHODOLOGY

Detailed explanation-1: -The Independent variable is the color of the light (white, blue, green, red). The dependent variable is plant growth (increase in plant height). Controlled variables are temperature, water and air.

Detailed explanation-2: -Yellow and white light have the lowest effect on plant growth. Red light impacts plant growth in several ways, including during the blooming and flowering phase. Certain specific red wavelengths will increase the production of a hormone in a plant’s vegetation that prevents the breakdown of chlorophyll.

Detailed explanation-3: -The dependent variable depends on the independent variable. The amount that the plants grow depends on the amount of sun they get. The independent variable is what you change, and the dependent variable is what happens because of the change.

Detailed explanation-4: -Independent variable: amount of sunlight. Dependent variable: growth of plant.

Detailed explanation-5: -In an experiment to determine the absorption of light of different colors, the independent variable is the color or the wavelength of the light. The dependent variable is the amount of absorption.
