J) eukaryotic
cells are given shape bye proteins folding into a tree demtional shape. the cell wall acts as the first line of defense of
letting things through the cell. the tight junction dose not allow molecules and ions to pass through the the space between
cells. the gap function are channels that allow passage of cells and ions. desmosome is a region were membranes of two
cells are heled together through a fiber called keratin joins the cell desmosome. microflaments is the function in the structure
and movement in eukaryotic cells
