A semi-permeable membrane is a membrane which allows cells to pass through it. The cells which make up the membrane of the inside of the cheek of the human mouth, for example, are semi-permeable. This allows things, like nicotine for example, to be absorbed through the membrane walls while the walls maintain structural integrity.

Does constant gradient have anything to do with passive transport?
No, constant gradient does not directly relate to passive transport. Passive transport is the movement of molecules across a membrane without the use of cellular energy, while constant gradient refers to a consistent change in concentration over a distance. However, the presence of a constant gradient can facilitate passive transport by driving the movement of molecules down their concentration gradient.
How can a door greeter relate to a cell membrane?
a cell membrane is semi-permeable. meaning that it selectively chooses between what can go in and out of the cell. A door greeter is similar to this because a door greeter can tell who to allow in/out of the building they are in.
How does the cell membrane structure relate to its function?
The cell membrane is composed of a phospholipid bilayer with embedded proteins that regulate the passage of substances in and out of the cell. This structure allows the cell membrane to be selectively permeable, controlling the movement of molecules and ions. This is crucial for maintaining cellular homeostasis and communication with the external environment.
How does difference in concentration relate to movement of substances across the membrane?
the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport
What does the Cell Membrane relate to?
The cell membrane is a semi-permeable barrier that surrounds the cell, controlling the movement of materials in and out of the cell. It plays a crucial role in maintaining cell structure, protecting the cell's contents, and facilitating communication with the external environment.
How does the permeability of the plasma membrane relate to homeostasis?
who the knows
How is the cell membrane facilitated diffusion transported?
In Facilitated diffusion materials are transported across the plasma membrane without using up any energy. Plasma membranes is made up of phospholipid bilayers consisting of proteins which help in the transportation of larger materials.
How does the surface are to volume ratio relate to the cell membrane?
they're cousins
What is osmosis and how does it relate to water?
Osmosis is the movement of water molecules from an area of low solute concentration to an area of high solute concentration across a selectively permeable membrane. This process helps maintain balance in living organisms by allowing water to move in and out of cells to regulate their internal environment.
How does the equation for photosynthesis relate to the equation for cellular respiration?
Because the end products of photosynthesis (glucose and oxygen) are the requirement to start cellular respiration.
How does the structure of an organelle relate to its function?
The structure of an organelle is directly related to its function. For example, the double membrane structure of the mitochondria provides compartments for different stages of cellular respiration. The shape and internal organization of an organelle determine how it carries out its specific role in the cell.
How does conduction and convection relate?
conduction, heat transport by direct contactconvection, heat transport by mass movement driven by density changes with temperatureradiation, heat transport by electromagnetic radiation
