What Are Cells?

Cells are the basic unit of life, and are the smallest structural and functional unit of living organisms. They are responsible for carrying out all of the necessary functions of life, such as metabolism, growth, and reproduction.

Cells come in many different shapes and sizes, but they all have certain features in common. They are surrounded by a membrane, which separates the interior of the cell from the outside environment. Within the cell, there is a variety of structures and organelles, each with its own function. For example, the nucleus contains the genetic material of the cell, while the mitochondria are responsible for producing energy.

There are two main types of cells: prokaryotic and eukaryotic. Prokaryotic cells are simple, single-celled organisms, such as bacteria. They do not have a nucleus or other membrane-bound organelles. Eukaryotic cells, on the other hand, are more complex and can be found in all multicellular organisms. They have a nucleus and a variety of organelles that perform specific functions within the cell.
