What is The plasma membrane helps to maintain a cells what?
The plasma membrane helps to maintain homeostassi within the cell by allowing substances to move in and out of the cell the plasma membrane is used to maintain homeostasis within the cell by allowing substances to move in and out of the cell
What organelle moves substances across the cell in one direction?
The plasma membrane surrounding animal cells is where the exchange of substances inside and outside of cells takes place. Some substances need to move from the extracellular fluid outside cells to the inside of the cell, and some substances need to move from the inside of the cell to the extracellular fluid.Some of the proteins that are stuck in the plasma membrane help to form openings (channels) in the membrane. Through these channels, some substances such as hormones or ions are allowed to pass through. They either are "recognized" by a receptor (a protein molecule) within the cell membrane, or they attach to a carrier molecule, which is allowed through the channels. Because the plasma membrane is choosy about what substances can pass through it, it is said to be selectively permeable.
Which type of molecule can move passively across the membrane?
Water can move passively through a membrane by moving through the pores of a cell. Other substances cannot move through a cell membrane.
Which molecules are often embedded within the lipid to help substances move through the membrane?
proteins
How do protest move substances through their cell bodies?
They use organelles and sub-organelles, as they are eukaryotic.
What proteins move need substances or waste materials through the plasma membrane?
transport proteins
What does a plasma membrane protein do?
Helps substances move in and out of the cell

What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The name of the membrane that allows movement of water and substances through the process of active and passive transport is semipermeable membrane.
How does plasma move through the convection layer of the sun?
convection cells
Active transport requires what?
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.
Which type of molecule can move passively across the membrane?
Water can move passively through a membrane by moving through the pores of a cell. Other substances cannot move through a cell membrane.
What is used to move a substance through a membrane in active transport?
Electrochemical gradient is used to move substances through a membrane in active transport.
What are three materials that move through a cell membrane?
Sodium, potassium and calcium are the three things that move through the plasma membrane. There are many other molecules and ions that do move through cell membrane. Plasma membrane have a selective permeable property.
The property of only allowing certain substances to move through it?
Selective permeability
