The plasma membrane, or cell membrane, is a vital biological barrier that surrounds the cell, composed of a phospholipid bilayer with embedded proteins. It regulates the entry and exit of substances, thus maintaining the cell's internal environment. Additionally, it facilitates communication through receptor proteins, supports the cell structurally, and enables cell recognition through carbohydrate molecules on its surface. This selective permeability is crucial for the cell's homeostasis and overall function.

Hypotonic : A solution that has a lower amount of solute in the solution is referred to as a hypotonic solution: Hypo=less, tonic=strength. A cell contains less amount of water than a hypotonic solution.

Isotonic: At the cellular level, isotonicity may pertain to a property of a solution in which its solute concentration is the same as the solute concentration of another solution with which it is compared.

Hypertonic: Hyper= more, tonic=strength. A solution that has more amount of solute than solvent in a solution is referred to as a hypertonic solution. If the cytosol of the cell is a hypertonic solution, then it suggests that the surrounding environment is of a hypotonic solution.

1. A hypotonic solution is a solution that has a lower concentration of solute compared to the cell. Solutions are mixtures composed of a solute and a solvent. The solute is the substance present in a lower amount, and the solvent is the substance present in greater amount. A hypotonic solution example is salt water.

2. An isotonic solution refers to the state when two solutions have equal concentration of solutes across a semipermeable membrane. This state allows for the free movement of water without the dilution of solutes on either side and keeps cells functioning properly.

3. A hypertonic solution is any external solution that has a high solute concentration and low water concentration compared to body fluids. In a hypertonic solution, the net movement of water will be out of the body and into the solution.

The plasma membrane is primarily composed of a lipid bilayer made of phospholipids, with hydrophilic heads facing outward and hydrophobic tails inward. It contains embedded proteins that serve various functions such as transport and signaling. Cholesterol molecules are interspersed to maintain membrane fluidity. Carbohydrates attached to proteins and lipids aid in cell recognition and adhesion. This structure creates a dynamic, semi-permeable barrier regulating substance exchange and communication.

A cell is the basic structural and functional unit of life. It is the smallest unit of an organism that is capable of independent functioning. Cells are surrounded by a membrane and contain genetic material (DNA or RNA) and various organelles that perform specific functions necessary for life processes. There are two main types of cells: prokaryotic cells, which lack a membrane-bound nucleus and organelles, and eukaryotic cells, which have a nucleus enclosed within a membrane and contain organelles. Cells are the building blocks of tissues, organs, and ultimately, organisms.

He pioneered the modern concept of pathological processes by his application of the cell theory to explain the effects of disease in the organs and tissues of the body. He emphasized that diseases arose, not in organs or tissues in general, but primarily in their individual cells. Moreover, he campaigned vigorously for social reforms and contributed to the development of anthropology as a modern science.
