Question | Answer |
---|---|
What is diffusion? | When molecules move from areas where there's a lot of them to areas where there's less of them |
What is osmosis | Diffusion that uses liquid/water |
Why is osmosis important? | It maintains a balance (homeostasis) in the cell |
Where does photosynthesis occur in the plant? | Chloroplast |
Where does cellular respiration occur in the animal cell? | In the mitochondria |
What is active transport? Does it require energy? | When it's a low area of concentration to an area of high concentration |
What is passive transport? Does it require energy? | When it's a high area of concentration to an area of low concentration |
Why do animal cells need respiration? | It's how they get energy |
Why do plant cells need photosynthesis? | They get glucose and energy from it |
What is endocytosis? | When molecules are transported by vesicles into the cell (food) |
What is exocytosis? | When molecules are transported by vesicles out of the cell (waste) |
What is vesicle? | A transport and storage structure in the cell's cytoplasm |
