Hey mate.....

here's Ur answer......

Yes ,it's very true that plants height can be produced by the intensity of light. Different plants differs in their need of the brightness of light. Plants who do not get sufficient light becomes yellowish in colour.

The hormone responsible for plants growth is Auxin and plants require proper sunlight to grow ....Their height can also be increased by using artificial lights...

Hope it Helps❤

Answer 2

1. Hypothesis:

• Yes, it's very accurate that a plant's height can be produced by the intensity of light.
• Different plants need a light with different brightness.
• Plants that do not get sufficient light to become yellowish.

2. Dependent variable:

• If the amount of sunlight is increased, then plant growth will increase.
• The data supported the hypothesis that plant growth increases as the number of sunlight increases.

3. Independent variable:

• Plants in the shade are less in height than plants in the sun. Sunlight and growth are related to each other.

• If the amount of sunlight will increase, then plant growth will increase.
• The data supported the hypothesis that plant growth increases as the number of sunlight increases.

4. Controlled variable:

• Here plant height is the dependent variable that responds to the change in the independent variable.
• Each plant is exposed to an equal amount of sunlight, so here sunlight is the control variable.
• They are also grown in the same-sized pot and given equal water.
