Question

PLEASE ANSWER, I'll MARK BRAINLIEST!!! Plants respond to their environment in many different ways. Design a controlled experiment to test the effect of one environmental factor (such as light, the acidity of precipitation, etc.) on some aspect of plant growth. In your experimental design be sure to:

Part A: State the hypothesis, making sure to identify what you are testing.

Part B: List the steps of the procedure.

Part C: Identify the independent and dependent variables in the experiment.

Answer 1

Answer:

Aim: to show the response of the plant to the light (environmental factor)

materials required: a potted plant, a place where there is a good availability of sunlight

procedure:

1. take the potted plant and keep it in a place where there is a good availability of sunlight.
2. leave it atleast for half a day in that sunlight.
3. observe it after sometime.

Observation: we observe that the plant bends in the direction of sunlight.this is called as phototropism.

hypothesis: this bending of plants is due to the presence of Auxins, the plant hormone which is responsible for phototropism.

result:the response of plant to the light (phototropism) has been observed.
