cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature.
Cells emerged on Earth about 4 billion years ago. All cells are capable of replication, protein synthesis, and motility. Cells are broadly categorized into two types: eukaryotic cells, which possess a nucleus, and prokaryotic cells, which lack a nucleus but have a nucleoid region.
Cells are the basic unit of life. In the modern world, they are the smallest known world that performs all of life's functions. All living organisms are either single cells, or are multicellular organisms composed of many cells working together.
Cells is an international, peer-reviewed, open access journal on cell biology, molecular biology, and biophysics, published semimonthly online by MDPI.
Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life. Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane.
A cell is the smallest living organism and the basic unit of life on earth. Together, trillions of cells make up the human body. Cells have three parts: the membrane, the nucleus, and the...
Cells are the smallest common denominator of life. Some cells are organisms unto themselves; others are part of multicellular organisms.
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
The cell is the fundamental organizational unit of life. All living things are composed of cells, which then further subdivide based on the presence or absence of the nucleus, into two types: eukaryotic cells (Greek, Eu=true, karyo=nut, nucleus) - these cells are present in all the human, animal and plants with a clear, distinct nucleus.
Cells are the smallest unit of life and the building blocks for all organisms. Each component of a cell has its own function. Animal and plant cells differ and they have similarities.
