Science - Cell Energy
How Do Organisms Get Energy from Food?
Both plant and animal cells must break down food molecules to get energy from them
What three things are produced during cellular respiration?
Carbon dioxide, water and energy (ATP)
What are the 2 ways in which cells get energy?
Cells get energy by cellular respiration and fermentation
Name two ways cells can get energy from food.
Cellular respiration and Fermentation.
Where does cellular respiration take place in plant and animal cells?
Cellular respiration takes place in structures called mitochondria in the cells.
Where is Chlorophyll found?
Chlorophyll is found in chloroplasts
What is the main pigment used in photosynthesis?
Chlorophyll is the main pigment used in photosynthesis
In which cell structures does photosynthesis take place?
Chloroplasts. Chloroplasts are found inside plant cells.
How Is Fermentation Different from Cellular Respiration?
During fermentation, cells break down glucose without oxygen whereas oxygen is needed for cellular respiration.
What two materials are needed for cellular respiration?
Glucose and oxygen
Do your body cells always use cellular respiration to break down glucose? Explain your answer.
No not all the time. Normally body cells use cellular respiration to get energy but with vigorous activity like exercise, not enough oxygen is available. When cells don't have enough oxygen, they must use fermentation to get energy.
What are the 2 products of Photosynthesis?
Oxygen and glucose
How do the processes of photosynthesis and cellular respiration work together?
Photosynthesis uses carbon dioxide and water and produces glucose and oxygen. Plant and animal cells use glucose and oxygen to make ATP in cellular respiration. Cellular respiration releases carbon dioxide and water. These are used by plant cells in photosynthesis
What kind of cells have chloroplasts?
Plant cells have chloroplasts
Why do plant cells need both chloroplasts and mitochondria?
Plant cells need chloroplasts for photosynthesis and they need mitochondria for cellular respiration, which gives them energy like what is needed for any living organism.
How Does a Plant Make Food?
Plants use carbon dioxide, water, and the sun's energy to make food in a process called photosynthesis
What is the food plants make?
The food plants make is a simple sugar called glucose.
What is Mitochondria?
They are organelles that act like a digestive system that takes in nutrients, breaks them down, and creates energy for the cell.
Is respiration a chemical reaction? YES or NO
YES
