| Question | Answer |
| name three particles able to fit through freely across the cell membrane | protein, water, and air particles |
| explain osmosis in your own words | osmosis is like diffusion but in water.it is where and unequal amount of water and protein particles gets distributed equally |
| how are diffusion and osmosis the same/different | they are the same because they both distribute particles. they are different because one is gas particle and one is liquid particles |
| Selectively permeable membrane | it means something only picks/lets certain things in/out e;g the cell membrane |
| diffusion | diffusion is the distribution of air particles moving away from a more dense/congested to a less dense area |
| concentration gradient | it means something goes from higher to lower concentration |
| osmosis | osmosis is when you have water and protein particles getting dispersed into equal amounts of both mixed |
| turgidity in a plat cell | if a plant cell is turgid it meas the plant is healthy and the vacuole is filled/watered good. when the vacuole is filled it creates turgor pressure making the cell wall swell which makes a plat cell turgid |
| when to use exocytosis | a cell uses this to let out waste and let out good toxins to help the body |
| why is phagocytosis called cell eating | it is called cell eating because when it lets things in the cell it opens up like a mouth eating food hence the name cell eating |
| why is air freshener a good example of diffusion | it is good because it is used a lot in everyday life and it is meant to diffuse and spread across a room to freshen it up. a good example is diffuser candles or car fresheners |
| how is using to much fertilizer bad | it could kill bugs and other animals, it could cause overgrowing, and could lead to really green grass making more animals eating it |
