Which is the correct term for the movement of an electrical charge across a membrane?
The correct term for the movement of an electrical charge across a membrane is "ion transport." This process involves the movement of ions such as sodium, potassium, chloride, and calcium across cell membranes, which is crucial for various physiological functions in living organisms.
What are organisms that have plasma membranes?
All living organisms have plasma membranes as they are essential for controlling the movement of substances in and out of cells. This includes bacteria, fungi, plants, and animals.
Do plants have a cell membrane?
Yes, plants have cell membranes. Cell membranes are a vital structure in all living cells, including plant cells, as they help regulate the movement of materials in and out of the cell.
Do plants have cell membranes?
Yes, plants have cell membranes. Cell membranes are found in all living cells, including plant cells, and they serve as a protective barrier that controls the movement of substances in and out of the cell.
Why movement across a membrane of a cell is vital for its survival?
Beacuse without it life would not be worth living!

What is required in all living things in order for gas exchange to occur?
A respiratory surface, such as lungs or gills, is required for gas exchange in all living things. This surface must be moist and thin to allow for efficient diffusion of gases. Additionally, a mechanism for moving gases, such as breathing or circulation, is needed to ensure the transport of gases to and from the respiratory surface.
Do plants have cell membranes?
Yes, plants have cell membranes. Cell membranes are found in all living cells, including plant cells, and they serve as a protective barrier that controls the movement of substances in and out of the cell.
What do living systems have that separates the internal chemicals from the external chemical environment?
Living systems have cell membranes that separate internal chemicals from the external chemical environment. These membranes control the movement of substances in and out of the cell, allowing for selective exchange of molecules and maintaining internal conditions necessary for life.

Is it true that viruses have complex membranes that control what moves in and out of their cells?
Viruses do not have complex membranes like eukaryotic organisms have. Viruses also do not have cells, nor are they technically living organisms. There is no need for viruses to control the movement of material in and out of the viral particles.
Which microbes have cell membranes?
All living cells, including microbes such as bacteria, archaea, fungi, and protozoa, have cell membranes. The cell membrane acts as a barrier that separates the cell from its environment, regulates the movement of molecules in and out of the cell, and plays a crucial role in maintaining cellular homeostasis.
Is a cell membrane part of every living cell?
Yes, a cell membrane is a fundamental structure present in all living cells. It surrounds the cell's contents and regulates the movement of substances in and out of the cell.
Do plants and animals have cell membranes?
Yes, both plants and animals have cell membranes. Cell membranes are essential components of all living cells, acting as a semi-permeable barrier that regulates the movement of substances in and out of the cell.
The movement of water across a membrane is trem?
The movement of water across a membrane is termed osmosis. This process involves the movement of water molecules from an area of high concentration to an area of low concentration through a selectively permeable membrane, such as a cell membrane. Osmosis plays a crucial role in maintaining the balance of water and solutes within living organisms.
Why does NaCl not require a transport protein for diffusion?
NaCl can diffuse freely across cell membranes through ion channels or transporters that allow for passive movement down its concentration gradient. As a small and simple molecule, NaCl does not require a specific transport protein for diffusion like larger or more complex molecules.
