ALL living things (organisms) are composed of
What are CELLS?
100
The nucleus is the control center of the cell and also stores
What is DNA / HEREDITARY INFORMATION?
100
This cell structure regulates the flow of molecules into and/or out of the cell.
What is the CELL MEMBRANE?
100
True or false? Green plants carry out the process of cellular respiration?
What is TRUE?

A science student made a wet mount of an onion cell, but forgot to use salt water. The student could add the salt water after using what method?
What is the paper towel method?
200
The Cell Theory states that all cells come from
What are OTHER CELLS?
200
This structure synthesizes (makes) proteins, such as enzymes.
What is the RIBOSOME?
200
True or false? The processes of active transport and diffusion are BOTH used to move molecules into or out of cells.
What is TRUE?
200
We refer to photosynthesis and respiration as the "cell energy cycle" because the _________ of one process are the __________ of the other process and vice versa.
What are OUTPUTS/INPUTS and INPUTS/OUTPUTS?
200
In the Diffusion Through a Membrane lab we saw that glucose could cross the cell membrane, but starch could not. Starch could not cross because
What is STARCH IS A LARGE MOLECULE?
300
To maintain homeostasis, organisms must respond to changes in their internal and external environments. For example, the eye will respond by closing the pupil when it detects bright light. The light is a
What is STIMULUS?
300
This cellular structure is responsible for releasing energy from nutrients.
What are MITOCHONDRIA?
300
Active transport requires energy because it is a process that moves molecules from LOW to HIGH, against this.
What is the CONCENTRATION GRADIENT?
300
This chemical compound provides energy to living cells, which use it during cellular respiration to make ATP energy.
What is GLUCOSE?
300
If your teachers asked you to graph the following information, what would you title the Y-axis?
What is TEMPERATURE (oC)?
400
Before nutrients can be absorbed and used by cells, macromolecules must be broken down into their building blocks via this process.
What is DIGESTION?
400
The nucleus, mitochondria and cell membrane are ____________, while the brain, stomach and lungs are ______________.
What are ORGANELLES and ORGANS?
400
Diffusion does not use energy and instead relies on a concentration gradient for the movement of molecules to occur. Molecules move from areas of ________ concentration to areas of ________ concentration.
What is HIGH and LOW?

Just like green plants, and terrestrial animals, aquatic animals require glucose and this molecule to carry out cellular respiration.
What is OXYGEN?
400
In the beginning of the Diffusion Through a Membrane Lab, glucose and starch were inside the cell and iodine was in the surrounding water. Which two molecules were able to diffuse across the cell membrane?
What are GLUCOSE and IODINE?
500
This life process is the ONLY process not necessary for the survival of an individual organism.
What is REPRODUCTION?
500
This organelle provides structure and support to plant cells, and can even prevent the cell membrane from bursting when in hypotonic environments.
What is the CELL WALL?
500
Osmosis occurs in the beaker below. What type of molecule is represented by the bluish circles?
What is WATER (H2O)?
500
During the cell energy cycle in a plant cell, energy is converted into multiple forms. During photosynthesis, light energy is converted to glucose which is a form of ___________ energy. Then, during respiration, the glucose is converted to another form of chemical energy called _________ energy, which is necessary for all cellular processes
What is CHEMICAL and ATP?
500
In the Diffusion Through a Membrane Lab, we used chemical indicators. How did we know that starch remained inside the cell, based on our iodine starch indicator?
What is THE IODINE INSIDE THE CELL TURNED BLUE/BLACK, BUT THE WATER OUTSIDE REMAINED AN AMBER COLOR?
