100
The item that is intentionally changed in an experiment
What is the independent variable?
100
The cell structure that allows certain materials in and out of the cell.
What is the cell membrane?
100
The process plants use to make sugar using sunlight, carbon dioxide, and water.
What is photosynthesis?
100
The process when molecules move form a high concentration to a low concentration.
What is diffusion?
100
What were the results of the starch experiment?
The water in the iodine beaker did not turn purple, which means the starch did not pass through the dialysis tubing.
200
The factors that are kept the same in the experiment.
What are controlled variables?
200
The support frame for plant cells that keep it from collapsing.
What is the cell wall?
200
The process when cells use oxygen to burn sugar for energy.
What is cellular respiration?
200
The process when water moves through a membrane from a high water concentration to a low water concentration.
What is osmosis?
300
The test subjects that are used for comparison in an experiment.
What is the control group?
300
A cell structure that contains the DNA, which provides instructions to run the cell.
What is the nucleus?
300
The molecule needed to burn sugar during cellular respiration.
What is oxygen?
300
The cell is 95% water and the solution is 90% water.
What is an example of when a cell would shrivel?
400
The result that is measured to see if it changes.
What is the dependent variable?
400
Organelles that use sunlight to combine carbon dioxide and water to make sugar. Oxygen is also produced.
What are chloroplasts?
400
The waste gas that is produced during cellular respiration.
What is carbon dioxide?
400
The cell is 90% water and the solution is 95% water.
What is an example of when a cell would swell?
500
A beneficial effect produced due to the patient's belief in that treatment.
What is the placebo effect?
500
Organelles that use oxygen to burn sugar for energy.
What are mitochondria?
500
The processes happen in reverse.
What is the relationship between photosynthesis and cellular respiration?
500
The cell is 95% water and its in a 10% salt solution.
What is an example of a cell would swell?
