What are the specializations of the plasma membrane?
The plasma membrane specializes in controlling the movement of substances in and out of the cell through selective permeability. It also plays a role in cell communication and recognition through protein receptors embedded in the membrane. Additionally, the plasma membrane helps maintain the cell's shape and structure.
What help control what enters and leaves a cell?
The plasma membrane
Is messenger RNA a constituent of a plasma membrane?
No, messenger RNA (mRNA) is not a constituent of the plasma membrane. mRNA is a type of RNA molecule that carries genetic information from the DNA in the cell nucleus to the ribosomes in the cytoplasm where protein synthesis occurs. The plasma membrane is primarily composed of lipids and proteins that help regulate the passage of molecules into and out of the cell.

What is the general definition of the plasma membrane in an animal?
it is the boundry of control of what enters and exit the cells
When a potassium ion K plus moves from the soil into the vacuole of a cell on the surface of a root it must pass through several cellular structures what correctly describes the?
The correct description is that the potassium ion K+ enters the root cell through the plasma membrane by facilitated diffusion or active transport. It then moves through the cytoplasm and finally enters the vacuole by active transport using membrane transport proteins.
Can large polar molecules pass through the plasma membrane?
No, large polar molecules cannot pass through the plasma membrane.
What is a plasma membrane made of?
A plasma membrane is made of a phospolipid bi-layer. Think of a plasma membrane like a grilled cheese sandwich. The bread on the outside of the sandwich is similar to the polar head of the plasma membrane, and the cheese on the inside is similar to the fatty tails on the inside of the membrane. If you tried to run water through the grilled cheese sandwich it would not get through the cheese center, much like water will not get through the center of a plasma membrane.
What is the definition OS Plasma Cell Membrane?
boundry of the cell that controlls what enters and exits the cells
Selectively permeable part of the cell that controls what enters and exits the cell?
Plasma (Cell) Membrane
