Matter & Compounds
This term means anything that has mass and takes up space.
What is matter?
This cell structure controls what enters and leaves the cell.
What is the cell membrane?
This process moves molecules from an area of high concentration to an area of low concentration.
What is diffusion?
This word means the ability to cause change or do work.
What is energy?
This substance dissolved the shell of the egg in the osmosis lab.
What is vinegar?
These are the tiny particles that make up molecules.
What are atoms?
This type of transport moves materials through the membrane without using energy.
What is passive transport?
This is the diffusion of water through a selectively permeable membrane.
What is osmosis?
This molecule stores and supplies energy for the cell.
What is ATP (adenosine triphosphate)?
The egg shrank when water moved out of it into this thick liquid.
What is corn syrup?
This is a pure substance made of only one kind of atom.
What is an element?
This type of transport moves materials using energy from ATP.
What is active transport?
This occurs when water moves out of a cell, causing it to shrink.
What happens when a cell is placed in salt water?
This process uses sunlight to make food (glucose) for the cell.
What is photosynthesis?
The egg swelled when water moved into it during this part of the lab.
What is the water stage (hypotonic solution)?
This type of compound always contains carbon and hydrogen.
What is an organic compound?
This occurs when molecules are evenly spread on both sides of the membrane
What is equilibrium?
This occurs when water moves into a cell, causing it to swell.
What happens when a cell is placed in pure water?
This process breaks down food to release usable energy.
What is cellular respiration?
In the osmosis lab, this part of the egg acted as the cell membrane
What is the thin outer membrane under the shell?
This compound is inorganic and essential for life processes.
What is water (H₂O)?
This type of protein helps larger molecules cross the membrane during passive transport.
What is a transport (carrier) protein?
This describes when diffusion stops because molecules are evenly spread out.
What is equilibrium?
This statement describes the relationship between photosynthesis and respiration.
What is “Photosynthesis stores energy in glucose; respiration releases it as ATP”?
The gummy bear grew larger in water because this process occurred.
What is osmosis (water moving into the bear)?
