What is the independent variable, dependent variable, constant and control group?

Pea plant clones are giving different amounts of water for a three-week period. The first pea plant receives 400 milliliters a day. The second pea plant receives 200 milliliters a day. The third pea plant receives 100 milliliters a day. The fourth pea plant does not receive any extra water; the plant only receives natural ways of receiving water. The heights of the pea plants are recorded daily.


Please Help!! Thank you so much (:|||The independent variable, that the experimenter has direct control over, is the amount of water the plants are given. The dependent varialble, which is influenced by/the result of the independent variable, is plant height. The control group is the group that you are not altering at all, the plants that receive water via natural means.|||Independent = the things you change to the group (so amount of water)


Dependent = the result


Constant = the group that continues to receive something.


Control = the group you're using to compare your experiment's result with.
