The cell in action!

how things get in and out of the cell

diffusion the movement of paricles from an area of where the concentration is low to where the concentration is high to an area where their concentration is low
osmosis the diffusion of water through the cell membrane
passive transport the diffusion of particles through the proteins of the cell membrane from areas of high concentration to an areas of low concentration
active transport the movement of particles through the proteins of the cell membrane against the normal direction of diffusion( from low concentration to high concentration) this process requires the cell to use energy
endocytosis the process of bringing large particles into the cell by surrounding the cell membrane around a particle and enclosing it in a vesicle
exocytosis the process of removing large particles out of the cell. The endoplasmic reticulum surrounds its membrane around a particle, which then travels to the cell membrane for removel.
What lets in small particles into the cell? passive transport and active transport
What lets in big particles into the cell? endocytosis & exocytosis
What lets water and oxygen into the cell? diffusion & osmosis
What ways to let materials into the cell uses energy? active transport, endocytosis, & exocytosis
