Science-cell quiz
| Question | Answer |
|---|---|
| diffusion | The movement of particles from high density, crowded areas, to low density less crowded areas. |
| Do cells need to use energy for diffusion? | No |
| osmosis | The diffusion of water through cell membranes |
| semipermeable | only certain substances can pass through a semipermeable membrane |
| Water is made up of what particles? | molcecules |
| Why would red blood cells burst if you placed them in pure water? | because water molecules would flood into the cells due to osmosis |
| passive transport | The movement of particles across a cell membrane without the use of energy |
| active transport | The movement of particles across a cell membrane with the use of energy |
| endocytosis | The active transport process by which a cell surrounds a large particle, such as a protein, and encloses the particle in a vesicle to bring the particle into the cell |
| exocytosis | An active transport process where the cell forms a vesicle around a large particle within the cell, then carries the particle to the cell membrane and releases it through the membrane. |
| photosynthesis | The process where plants capture energy from the sun and change it into food. |
| pigments | molecules that absorb light energy |
| What is the main pigment used in photosynthesis and what does it do? | Chlorophyll, it gives plants their green color and is found in chloroplasts |
| Describe the process of photosynthesis: | carbon dioxide+water+light energy= glucose and oxygen |
| Plants use the energy captured by chlorophyll to.... | change carbon dioxide and water into food |
| Why do cells need energy? | To live, grow, and reproduce |
| Where do plant cells get their energy? | From the sun |
| Where do many animal cells get their energy? | From food |
| Why is glucose important for a plant cell? | When plants make glucose, they convert the sun's energy into a form of energy that can be stored and used later. |
| What is glucose? | A carbohydrate, a simple sugar. |
| Photosynthesis produces | Oxygen and glucose |
| Cells use what to break down food | oxygen |
| cellular respiration | The way cells use oxygen to produce energy from food. |
| Explain the cellular respiration process... | food/glucose is taken into the cell, and broken down into Carbon Dioxide and Oxygen. Energy is released. |
| Where does cellular respiration take place? | in the cell cell membrane of prokaryotic cells, and in eukaryotes, it's in the mitochondria. |
| fermentation | the breakdown of food without the use of oxygen |
| Why do your muscles hurt when you work out? | The cells can't get enough oxygen |
| What is ATP and what does it supply? | Adenosine triphosphate, supplies energy that fuels the cell's activities |
