Cell Transport 11.6
| Question | Answer |
|---|---|
| What is the main difference between active transport and passive transport? | Passive transport moves substances throughout the cell without using the cell’s energy and active transport moves substances using the cell’s energy. |
| Which form of energy is necessary in photosynthesis? | light |
| Which substance is released as a waste product during photosynthesis? | oxygen |
| Materials enter and leave the cell through openings in its ____. | membrane |
| Which substance is broken down during glycolysis? | glucose |
| The green color of tree leaves is due to green light energy reflected from ____. | chlorophyll |
| Respiration is the process in which organisms break down food to release ____. | energy |
| Substances too large to pass through the cell membrane enter the cell in a process called ____. | endocytosis |
| The process that releases energy without using oxygen is ____. | fermentation |
| Photosynthesis is the process in which plants use energy from light to produce ____. | food |
| Active transport occurs when ____ is used to move substances through a membrane. | energy |
| During periods of strenuous activity, muscle cells run low on ____. | oxygen |
| The passive transport of water through a membrane is ____. | osmosis |
| The energy used in photosynthesis comes from _________. | sun |
| One property of a molecule that determines whether it will pass through a semipermeable membrane is __________. | size |
| A plant wilts as a result of the process of ____________________. | osmosis |
| The compound that moves through cell membranes by osmosis is __________. | H2O |
| ________ is important because it changes food energy into a form all cells can use. | respiration |
| What is the chemical equation for photosynthesis? | carbon dioxide + water —> glucose + oxygen + water 6CO2 + 6H2O —> C6H12O6 + 6O2 |
| Explain how photosynthesis is related to aerobic respiration | Aerobic respiration is the opposite of photosynthesis. both need each other to carry out the process. The products of one are the reactants of the other. |
| How are osmosis and diffusion different? | Osmosis is the movement of water and is always the movement in the membrane. Diffusion does not need a membrane to make molecules and Diffusion is the movement of molecules. |
