- Osmosis is the diffusion of a solvent through a differentially permeable membrane. In biological systems, the solvent will usually be water.
- Osmosis will occur whenever the water concentrations are different on either side of a differentially permeable membrane. Osmosis can be defined as the movement of water molecules from a higher water concentration area to the area of less water concentration through a semipermeable membrane.
- In other words, it can be defined as the diffusion of water molecules through a semipermeable membrane. It is a special case of diffusion of water (High to low). For example, water in the roots of plants is transported through osmosis.

The correct answer is option 'D': Plasma membranes contain chitin sugar in plants.
Explanation:
To understand why option 'D' does not belong to the process of osmosis, let's break down each of the options and analyze their relevance to osmosis.
a) The movement of water across a semipermeable membrane is affected by the amount of substances dissolved in it.
This option is directly related to osmosis. Osmosis is the process by which water molecules move across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. The movement of water is driven by the concentration gradient of solute particles. Therefore, this option is relevant to osmosis.
b) Membranes are made of organic molecules such as proteins and lipids.
This option is also relevant to osmosis. Membranes, including semipermeable membranes, are composed of organic molecules such as proteins and lipids. These molecules form a barrier that allows the selective passage of certain substances, including water, while restricting the passage of others. This selective permeability is essential for osmosis to occur.
c) Molecules soluble in organic solvents can easily pass through the membrane.
This option is also relevant to osmosis. Osmosis involves the movement of solvent molecules, typically water, across a semipermeable membrane. While water is the most common solvent involved in osmosis, other molecules soluble in organic solvents can also pass through the membrane. This option highlights the general concept of solute and solvent movement across membranes, which is applicable to osmosis.
d) Plasma membranes contain chitin sugar in plants.
This option does not belong to the process of osmosis. Chitin is a complex carbohydrate that is primarily found in the cell walls of fungi and the exoskeletons of arthropods, such as insects and crustaceans. It is not a component of plasma membranes in plants. Plasma membranes in plants are primarily composed of phospholipids, proteins, and other organic molecules, but not chitin. Therefore, this option is not relevant to the process of osmosis.
In conclusion, option 'D' does not belong to the process of osmosis because plasma membranes in plants do not contain chitin sugar.
