Frequency refers to the number of cycles per second, amplitude refers to the strength, and phase is the position of the wave on the time axis.
        
             
        
        
        
Answer:
<em>The answer is plant cells they would be the type of cells you would find a permanent. an animal cell would not have that.</em>
Explanation:
<em>The reason plant is the answer is because plant cells contain a cell wall made of cellulose to strengthen the cell. They also have a permanent vacuole which is filled with cell sap to help keep the cell turgid.</em>
<em>The reason why animal cells don't have a permanent is because Animal cells may have more than one vacuole, and they are smaller than a plant cell's. Vacuoles are used to store materials in the cell that may be used by the cell or wastes that must be moved out of the cell.</em>
