Cells 2 :) Flashcards
This is how our body keeps everything balanced and just right.
Example: When you play outside on a hot day, your body starts to sweat. Sweating helps cool you down so you don’t get too hot.
Homeostasis
This is when water moves from one place to another through a special barrier, like a cell wall.
Example: If you put a raisin in a cup of water overnight, it will swell up because water moves into it.
Osmosis
This is when things spread out from where there is a lot to where there is less.
Example: When you spray perfume in one corner of a room, the smell spreads all around.
Diffusion
Is when a cell large molecules, fluids, or even entire microorganisms by wrapping its membrane around them and bringing them inside.
Endosytosis - (En-do-sy-TOE-sis)
Is when a cell expels things, like waste or chemicals, by packing them in a little bubble and sending them out of the cell.
Exocytosis - (Ex-o-sy-TOE-sis)
