Cytoskeleton
Responsible for the shape of the cell and movement of its parts
Endoplasmic Reticulum (ER)
Synthesis and modifacation of proteins and other substances
Why is the plasma membrane said to be selectively permeable?
Only small, noncharged molecules can diffuse across the plasma membrane without assistance
During diffusion, molecules move from:
Higher concentration to lower concentration
During facilitated transport, carrier protiens transport molecules from:
Higher concentration to lower concentration
