- a is a passive process in which substances move freely through the lipid bilayer without the help of membrane transport proteins.
- b is the fluid portion of the cytoplasm containing water, dissolved solutes and suspended particles
- c They bud from the edges of the cisternae of the Golgi complex; they function to move enzymes back toward the entry face of the Golgi complex and to move proteins toward the exit face.

5 True/False Questions
anaphase → the phase in which the chromatin fibers condense and shorten into chromatids which are identical and held together by a centromere; late in this phase, the centrosomes begin the formation of the mitotic spindle; the nucleolus disappears and the nuclear envelope breaks down.
metaphase → During this the spindle microtubules align the chromatid pairs at the exact center of the mitotic spindle.
transmembrane proteins → They carry processed proteins from the exit face of the Golgi complex to the plasma membrane for incorporation into the plasma membrane itself.
hemolysis → process that moves materials out of a cell by fusion of a vesicle with the plasma membrane.
primary active transport → is the process in which some solutes, which must enter or leave cells against their concentration gradients, can be moved by use of ATP specifically for energy by the cell.
