Mr. Belvedere designs an experiment to test the effect of different colored light on the rate of photosynthesis. He sets up his experiment using elodea, 25watt bulbs, 30mL of distilled water, and 5g of sodium bicarbonate. Plant 1 is exposed to no light. Plant 2 is exposed to white light. Plant 3 is exposed to green light. Plant 4 is exposed to red light.And Plant 5 is exposed to blue light.a.What is the dependent variable?b.What is the independent variable?c.What is the control group?d.What are the experimental groups?e.List the constants Mr. Belvedere put in place.

dependent variable: rate of photosynthesis independent variable: different colored light control group: plant 1 experimental groups: plant 2, plant 3, plant 4, plant 5

i don't know the constant

Damon · Answer

dependent = rate independent = color control = no light groups = all the different colored constants = 25 watts , 30 mL, 5g bi so I agree

a. The dependent variable in this experiment is the rate of photosynthesis. It is the variable that is being measured and is expected to change in response to the independent variable. b. The independent variable is the different colored light. It is the variable that is being manipulated and controlled by Mr. Belvedere. c. The control group in this experiment is Plant 1, which is exposed to no light. The control group is used as a baseline for comparison and does not receive the independent variable being tested. d. The experimental groups are Plants 2, 3, 4, and 5, which are exposed to white, green, red, and blue light, respectively. These groups are receiving different levels of the independent variable to observe any potential effects on the dependent variable. e. The constants that Mr. Belvedere put in place are: - The type of plant used (elodea) - The wattage of the bulbs (25 watts) - The volume of distilled water (30 mL) - The amount of sodium bicarbonate (5g) These constants are kept consistent across all the experimental groups to ensure that any differences observed in the dependent variable are due to the different colored lights and not other factors.
