2025年1月6日 · Cell theory states that the cell is the fundamental structural and functional unit of living matter. In 1839 German physiologist Theodor Schwann and German botanist Matthias Schleiden promulgated that cells are the “elementary particles of organisms” in both plants and animals and recognized that some organisms are unicellular and others multicellular.

The cell is the basic structural and functional unit of all forms of life.Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function.

2021年2月22日 · 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.

2021年2月15日 · Il y a chaque jour des cellules anormales qui sont produites dans notre corps, et que notre système immunitaire est chargé de détruire. Il le fait en général efficacement pendant toute notre vie.

The meaning of CELLULE is a small cell.

The human body is composed of about 10 trillion cells. Everything from reproduction to infections to repairing a broken bone happens down at the cellular level. Find out all about cells.

In biology, the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm.

Neutrons are uncharged subatomic particles of essentially the same mass as protons. They contribute to the structural stability of the nucleus—if there are too many or too few, the nucleus may disintegrate by radioactive decay—but they do not alter the chemical properties of the atom.

La grande majorité des cellules possèdent une copie complète de l’ADN de l’organisme dont elles font partie. On peut classer les cellules (et les organismes vivants qu’elles constituent) en deux grandes catégories en fonction de la présence ou de l’absence d’un noyau : …

2023年9月20日 · Tous les êtres vivants sont composés d'une ou plusieurs cellules. Ces cellules sont des unités morphologiques et physiologiques, ce qui veut dire qu'elles sont composées de structures complexes et qu'elles ont des fonctions spécialisées.
