What are the independent and dependent variables in plant growth?
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.
Is the growth of a plant independent or dependent?
dependent variable
In a plant experiment, some plants will get fertilizer, others will not. The scientists change the amount of the fertilizer to observe the effects on plant growth. Plant growth is the dependent variable.
Is height a dependent or independent variable?
The dependent variable (height) depends on the independent variable (age). An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that.
Is sunlight an independent variable?
In this case, the number of hours of sunlight is the independent variable and the height of the plant is the dependent variable, because the change in the height depends on the hours of sunlight, not the other way around.
Does light affect plant growth experiment?
Does the wavelength of light affect a plant’s growth experiment? Answer 1: Yes, color does affect plant growth. Blue light will allow the plant to grow leaves and other vegetation and red light with blue allows the plant to grow flowers.
How does sunlight affect the height of plants?
If a plant gets limited sunlight, the photosynthesis process slows down and the plant begins to grow upward and stretch their stems to reach for the sunlight (this process is called etiolation).
What variable is sunlight?
independent variable
In this case, the number of hours of sunlight is the independent variable and the height of the plant is the dependent variable, because the change in the height depends on the hours of sunlight, not the other way around.
Can the amount of sunlight be an independent variable?
The independent variable is the amount of sunlight each plant receives. 2. In an experiment to test the effect a gasoline additive has on gas mileage in a car, the amount of additive per gallon is the independent variable.
What does the sun do for plants?
Plants rely on the energy in sunlight to produce the nutrients they need. But sometimes they absorb more energy than they can use, and that excess can damage critical proteins. To protect themselves, they convert the excess energy into heat and send it back out.
How are plants grow in response to light?
For the earlier plant experiment, “How Plants Grow In Response to Light,” the growth of the plant is the dependent variable being observed The plant growth is in response to changes in the amount of light the plant receives, is the independent variable. Also, what are the independent and dependent variables in an experiment?
How does lack of sunlight affect plant growth?
The lack of sunlight stunted photosynthesis and therefore the sprouts were not able to produce the chlorophyll needed to create a green color. Overall, this experiment depicts just how important the sun is to the survival of plants and also humans (oxygen supply).
What is the independent variable in a plant growth experiment?
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. Every experiment should have only one independent variable. Click to see full answer. Also asked, what is the independent variable in a plant growth experiment?
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. Every experiment should have only one independent variable.
