Which of the statements claims about light is incorrect?
Light is a form of energy that is necessary for photosynthesis
The intensity of light decreases with increasing distance from its source
Different wavelengths of light can have different effects on plant growth and development
Plants are able to grow and develop normally without any exposure to light
Answers (1)
Correct option d)
In the absence of light, plants cannot develop and grow correctly.
A source of energy required for photosynthesis is light. Plants use light energy during photosynthesis to change carbon dioxide and water into glucose and oxygen.
Plants cannot carry out photosynthesis without light, which prevents them from generating the energy required for growth and development.
Indeed, as a light source is moved further away, its intensity decreases. The inverse-square law, which states that light intensity diminishes by the square of the distance from the source, is to blame for this.
The growth and development of plants can be affected differently by various light wavelengths. For instance, red light can encourage flowering and fruiting whereas blue light can stimulate vegetative development.
Overall, light plays a significant effect in regulating the distribution of plant species in various habitats and is a crucial abiotic component for plant growth and development.
Option d is the correct answer.
