Passive and active transport. Passive transport doesn't require the cell's energy, while active transport does.

What makes phospholipids the prime structure for making a cell selectively permeable?
The property of phospholipids that makes them ideal for making up the selectively permeable cell membrane is their ability to form a lipid bilayer. A hydrophilic head and a hydrophobic tail play an important role in the cell membrane.
What is the structure of a cell membrane in plant cells?
The cell membrane is composed of phospholipid bi-layer and proteins. The phospholipids are both hydrophillic and hydrophobic and makes the cell membrane be selectively permeable, that is allows only curtain molecules to pass through the membrane. The proteins function is to determine wchich molecules must go in and wchich shouldn't go inside the cell.
What makes it possible for the plasma membrane to self assemble?
The plasma membrane is able to self-assemble due to the properties of its constituent molecules, such as phospholipids. Phospholipids have hydrophilic heads and hydrophobic tails, which drives them to form a bilayer structure when exposed to water. This spontaneous assembly is driven by the hydrophobic effect and results in the formation of a stable and selectively permeable membrane.
Which type of membrane surrounds a cell?
this is the cell membrane made primarily of lipid molecules with proteins incorporated into it that aid in transport of molecules across the membrane
Describe the functions of two cell organelles shared by prokaryotes and eukaryotes?
They both share ribosomes and a membrane. The ribosomes makes protein while the membrane selectively choices what comes and goes from the cell.
What makes the cell membrane selective permeable?
A cell membrane is selectively permeable because it only allows particles to move across them due to different concentrations. Molecules move from areas of low concentration to high concentration.
What makes up a selectively permeable membrane?
Plasma membrane filters what the cell needs and keeps out what will harm it. this property is called selective permeability.
What makes phospholipids the prime structure for making a cell selectively permeable?
The property of phospholipids that makes them ideal for making up the selectively permeable cell membrane is their ability to form a lipid bilayer. A hydrophilic head and a hydrophobic tail play an important role in the cell membrane.
What is the cell membranes responsible for?
It is a selectively permeable membrane that allows certain substances in and out, but keeps harmful substances from entering the cell. It could be compared to the security guard at the door of an airport that makes sure that nobody dangerous gets in or out.

In what way is a cell membrane selective?
very complicated question that is better addressed by a cell biology text but in general cell membrane itself is non-polar and allows small non-polar molecules through it also has protein that are built to selectively let in molecule based on commands from the body

Why is it important for the cell membrane to be selectively premeable?
It makes it harder for viruses and free radicals to reach the nucleus.

Movement across the cell membrane made possible by a protein embedded in the cell membrane?
It is a selectively permeable membrane that allows certain substances in and out, but keeps harmful substances from entering the cell. It could be compared to the security guard at the door of an airport that makes sure that nobody dangerous gets in or out.
What would happen if the plasma membrane ruptures or break down?
Plasma Membrane is the outer covering of the cell that seperates its content from the surrounding medium. It is a selectively permeable membrane . If it rupture or breaks down the cytoplasm will come in direct contact with the surrounding medium and the act of selection will stop.
