Cell Components
A cell is the smallest structural and functional unit of a living organism. Thus, known as the building blocks of life because they are responsible for all life’s processes. Several components within a living cell are responsible for different roles. The first component of a cell is the cell membrane. It entails a semipermeable membrane forming the outermost part of the cell. It is made up of a protein layer sandwiched between two phospholipid layers. The membrane entails separating intracellular components from extracellular surroundings, offering structural support for the cell, and providing a fixed environment. It also facilitates the transportation of nutrients into the cell and toxic substances out. The membrane also transmits signals for communication between cells (McCance & Huether, 2018).
The second component of a living cell is the nucleus. It entails identified as a specialized structure made up of nucleoplasm and nucleolus isolated from the rest of the components by a nuclear membrane. The nucleus controls all functions within the cell, which include metabolism and growth, among others. It also houses the Deoxyribonucleic acid molecules, which contain the cell’s genetic information necessary to maintain the characteristics of the cell during mitosis.
Other cell components are the cytoplasm and cytoplasmic organelles. The cytoplasm is a gel-like fluid made up of water, proteins, and salts. It offers a base where other organelles can operate within a cell and provides a medium for chemical reactions. Cytoplasmic organelles incur to represent minor cell components suspended in the cytoplasm with different structures and functions. These organelles include lysosomes, ribosomes, mitochondrion, and Golgi apparatus, among others.
