what are the three main parts of the cell and their functions?

A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.

A cell is the basic unit of the structure and function of all living things.

A cell is one of the building blocks of life. Cells are membrane-bound groups of organelles that work together to allow it to function. Some of the major organelles include the nucleus, mitochondria, lysosomes, the endoplasmic reticulum, and the Golgi apparatus.

Cellular functions include such basic life processes as protein and lipid (fat) synthesis, cell division and replication, respiration, metabolism, and ion transport as well as providing structural support for tissues, protecting the body against disease or injury, and serving as selective barriers to the passage of ...

All cells share four common components: 1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; 2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; 3) DNA, the genetic material of the cell; and 4) ribosomes, ...

What is a cell? Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function. Cells are the basic structures of all living organisms.

However, all cells have three main parts, the plasma membrane, the cytoplasm and the nucleus. The plasma membrane (often called the cell membrane) is a thin flexible barrier that separates the inside of the cell from the environment outside the cell and regulates what can pass in and out of the cell.

Structures within cells have individual functions, and in general, no matter the structure, these can be reduced to three essential jobs: A physical interface or boundary with specific molecules; a systematic means of shuttling chemicals into, along or out of the structure; and a specific, unique metabolic or ...

The cell is structural and functional unit of all living things. Cell Structural Overview: The major parts of a cell are the nucleus, cytoplasm, and cell membrane. Nucleus: The nucleus contains a nucleolus and is separated from the cytoplasm by the nuclear envelope.
