Answer:
The correct answer is -
Independent variable - the amount (time period) of light given to pots.
Dependent variable - size of tomatoes
Control variable - dark or absence of light
Control group - pot placed in the darkroom.
Explanation:
The independent variable is the variable that is changed or manipulated in particular research or study to see the effect of that variable on dependent variable. In this case, the amount of light each pot gets is the independent variable.
The dependent variable is the variable that depends on the change in the independent variable. The size of tomatoes is the dependent variable here.
The control variable is the variable that remains in standard condition or condition which can be used to compare with the effect of the independent variable. The absence of light on one of the tomato pot is the control variable.
The control group is the group of subjects did not get any treatment that experiment group receives. The pot which is placed in the dark room is control group here.
Answer:
CO2 enters the stomata during the day when they are open for photosynthesis. In exchange, O2 exits the stomata. While the stomata are open, there is a risk of water loss resulting in wilting and maybe death. The stomata help to conserve water at night while they are closed. Also, their waxy covering “cuticle” helps minimize water loss. On a very hot day, the stomata May close to preserve water but it comes with a cost, because if they close, photosynthesis slows down.
