        Help!  

Term
Definition
Photosynthesis   A process in which plants convert sunlight, water, and carbon dioxide into food energy (sugar), oxygen, and water  
🗑
Cellular Respiration   The process by which the chemical energy of "food" molecuels is released and changed into ATP (energy)  
🗑
Chloroplasts   An elongated cell organelle containing chlorophyll where photosynthesis takes place  
🗑
Chlorophyll   A green molecule which uses light energy from sunlight to change water and carbon dioxide gas into sugar and oxygen  
🗑
Glucose   The sugar or food that the plants make for themselves  
🗑
Mitochondria   Rod-shaped organelles with a double membrane which converts stored in glucose into ATP (energy) for the cell  
🗑
Photosynthesis Equation   H2O+CO2+Light=O2+C6H12O6 [Water+Carbon Dioxide+Light=Oxygen+Glucose (Sugar)]  
🗑
Respiration Equation   O2+C6H12O6=H2O+CO2+ATP [Oxygen+Glucose (Sugar)=Water+Carbon Dioxide+energy]  
🗑
Diffusion   The movement of molecules from a dense area to a less dense area (no energy used)  
🗑
Osmosis   The diffusion of water across a selectively permeable membrane  
🗑
Active Transport   The movement of materials between a cell membrane (uses energy)  
🗑
Carbon Dioxide   a colorless, odorless gas produced by respiration and is absorbed by plants in photosynthesis.  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
