Question

1. what source of energy is the plant using?

glucose the light atp magic
experimental variables
what is measured during a controlled experiment?
when scientists set out to do an experiment, they first think about the variable that may affect the outcome of the experiment. a variable is any condition that may cause a change in the system being studied.
some variables are measured quantitatively, like temperature or height. other variables are measured qualitatively, like color or texture. the most important factor in a controlled experiment is that only one variable is changed to ensure that the effect of only one variable can be measured.
why?
model 1 - photosynthesis in an aquatic plant
the diagram in model 1 illustrates a setup of an aquatic plant in water.

1. what process is occurring in the plants cell to produce the gas bubbles that appear?
2. what is the gas?
3. what source of energy is the plant using?
4. depending on the environment the plant is in, more or less gas may be produced. suggest a method for measuring the rate of gas production from the aquatic plant in model 1.
5. why your group of environmental factors that may affect the rate of gas production in an experiment? these factors could be variables in the aquatic plant in model 1.

Explanation:

Plants use light energy during photosynthesis to convert carbon - dioxide and water into glucose and oxygen. ATP is an energy - carrying molecule produced during the process, but the initial energy source is light. Glucose is a product of photosynthesis, not the energy source. Magic is not a scientific energy source for plants.

Answer:

the light
