Osmosis
Which process involves proteins providing a pathway for large molecules to diffuse into the cell?
Facilitated Diffusion
Which type of transport requires cells to use up energy to move molecules across the cell membrane against the natural concentration gradient?
Active Transport
What are the 4 functions of cell division?
Repair injured body parts
Which structures in the cell help it to reproduce?
Centrioles
What is active transport and the forms of passive transport?
Active transport requires energy and moves molecules against the concentration gradient; passive transport includes diffusion, osmosis, and facilitated diffusion
What is passive transport and the forms of active transport?
Passive transport does not require energy and moves molecules down the concentration gradient; active transport includes symport, antiport, and uniport
Why do cells divide?
To repair injured body parts
