Water is transported by a passive transport called osmosis. Osmosis is diffusion of water across the membrane.
Carbon dioxide can diffuse passively through the cell membrane due to its small size and nonpolar nature. Water molecules can pass through the membrane via osmosis, a type of passive transport. Sodium ions are transported against their concentration gradient through active transport processes such as sodium-potassium pumps that require ATP for energy.
They are too large to be transformed by carrier proteins. They are moved across by Vesicles instead.
Water doesn't require channels to be transported across membranes because water is small enough to slip past the membrane; however, some cells do have channels, called aquaporins, which greatly increase the rate that water passes through the membrane.
The molecule will be transported across the membrane by way of a transport protein or protein channel.
The electron movement causes H+ ions to be transported to the cystolic side of the mitochondrial membrane from the mitochondial matrix. This creates the electrochemical gradient that is used to generate chemical energy (ATP from ADP)
During osmosis, water molecules are transported across a membrane from an area of higher concentration to an area of lower concentration.
Water molecules are transported across a membrane during osmosis. This movement occurs from an area of higher water concentration (dilute solution) to an area of lower water concentration (more concentrated solution) to reach equilibrium.
In osmosis, water is the main substance that is transported across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. This movement of water helps to equalize the concentration of solutes on either side of the membrane.

An apoplast is a space outside of a plant's plasma membrane through which water and soluble nutrients are transported across a tissue or organ.

Movement of water across a membrane is called OSMOSIS.
When will water stop moving across a membrane when the water concentration is equal on both sides.
The molecule will be transported across the membrane by way of a transport protein or protein channel.
Lipid solubility determines if it will diffuse across. The presence of specific protein carrier molecules determines if it will be transported across the membrane.
