Question

Reasoning question.... How many ways the light influences the rate of growth?

Answer 1

Answer:

When determining the effect of light on plant growth there are three areas to consider: intensity, duration and quality. Light intensity influences the manufacture of plant food, stem length, leaf color and flowering. Generally speaking, plants grown in low light tend to be spindly with light green leaves.

Answer 2

Answer:

• There are three factors taken into consideration while determining the effect of light in plants.
• They are intensity, duration, and quality.

Explanation:

• Light is one of the main factors that influence the plant growth as it induces photosynthesis.

• Plants depend on light to produce food and for the healthy working of the various cycles.
• There are three influences of light in the growth of plants.

• Intensity: Light intensity can affect the process of photosynthesis in plants. High intensity light promotes the growth of plants at a higher rate. The increase in light intensity results in the increase in oxygen level. As a result, photosynthesis takes place at a faster rate.

• Duration: The duration of light compensates the low intensity of light. Increased duration of light allows plant to make food and grows healthy.

• Quality: The quality of light promote photosynthesis, thereby, inducing higher rate of growth. Blue and red light facilitates the opening of stomata, and green light results in the closing of stomata. Complex light of red, blue and green help expands the surface area of leaf, and red light can increase the photosynthesis production.
