Which of the following is TRUE of a cell membrane?
Cell membranes allow ALL substances to pass through easily
It is selectively permeable so only certain molecules can pass through it
It acts more like a fluid than a solid because its molecules are constantly moving

prokaryotes are surrounded by a cell membrane and eukaryotes are not
prokaryotes have a nucleus and eukaryotes don't
eukaryotes have DNA and prokaryotes don't
eukaryotes have membranes around their nucleus and organelles and prokaryotes don't
Vacuoles are larger smaller( larger, smaller ) in plant cells than in animal cells.
Cell membranes form because the hydrophobic tails on phospholipids try to be near stay away from( be near, stay away from ) water.
