Passive transport refers to the movement of molecules across a biological membrane without the expenditure of cellular energy. This process occurs down the concentration gradient, meaning molecules move from areas of higher concentration to areas of lower concentration until equilibrium is reached. It includes simple diffusion, where small, non-polar molecules like oxygen and carbon dioxide can pass directly through the lipid bilayer of the membrane, as well as facilitated diffusion, where larger or polar molecules move across the membrane with the help of transport proteins, such as channel proteins or carrier proteins. Overall, passive transport is essential for maintaining the balance of molecules within cells and between different cellular compartments.

The process described, where many solute particles must use a channel protein to move from a high concentration inside the cell to a lower concentration outside the cell, is called "Facilitated diffusion." This process involves the passive movement of molecules across a biological membrane with the assistance of transport proteins. Channel proteins are one type of transport protein that facilitates the diffusion of specific molecules, such as ions or polar molecules, across the membrane by providing a channel through which these molecules can pass. Facilitated diffusion does not require energy input from the cell and occurs down the concentration gradient, from areas of higher concentration to areas of lower concentration.

Water is the major component of blood plasma, making up approximately 90-92% of its composition by volume. Blood plasma is the liquid portion of blood, composed mostly of water along with dissolved solutes, such as ions, nutrients, gases, hormones, and waste products. Water in blood plasma serves as the solvent for carrying nutrients, hormones, and other molecules throughout the body, facilitates gas exchange in the lungs and tissues, helps regulate body temperature, and maintains blood volume and pressure. The remaining components of blood plasma, including ions (such as sodium, potassium, and calcium), proteins (such as albumin, globulins, and fibrinogen), and other solutes, contribute to various physiological functions in the body.

Contractile vacuoles are organelles found in some protists and single-celled organisms, primarily freshwater unicellular organisms. These vacuoles are responsible for regulating the water content of the cell by actively pumping excess water out of the cell. Contractile vacuoles collect excess water from the cytoplasm through a process of osmosis, where water diffuses into the cell due to differences in solute concentration between the cell and its environment. Once filled, contractile vacuoles contract rhythmically, expelling the excess water from the cell to maintain osmotic balance and prevent cell swelling or bursting. This process is particularly important for organisms living in hypotonic environments where water uptake is significant.
