Cells are a vital part of existence as cellular structures form the basic foundations of life. The cell is a structural, functional, and biological unit in every plant, animal, and human body. Every cell is bound by a cell membrane that contains the different parts of a cell. They are incredibly small …
ATP meaning ATP means adenosine triphosphate and it is a molecule that carries energy within cells. Definition of adenosine triphosphate Adenosine triphosphate (ATP) is defined as a pyrophosphate molecule that provides energy for metabolic processes, i.e., cell survival. It is a complex organic high-energy compound that provides energy for metabolic processes to …
Plasmids in bacteria and other cells have a significant function in bioengineering. The meaning of plasmids, their functions, and their types will be explained in this article. Definition of plasmids in biology Plasmids are small extrachromosomal DNA molecules found within cells that can replicate independently because it is not attached to chromosomal …
The osmotic pressure formula and its concepts are critical to cells in biology. The equation is used to calculate the pressure when two solutions with different concentrations are separated by a semipermeable membrane. Osmotic pressure definition in biology Osmotic pressure is defined as the minimum pressure required to apply to a solution …
The thylakoid membrane function in a cell is the site that captures sunlight that is needed for photosynthesis. The structure of the thylakoid helps in accomplishing this role. Thylakoid Definition A thylakoid is a sheet-like membrane-bound organelle in chloroplasts and cyanobacteria that is the site of light-dependent photosynthesis reactions Thylakoids are made …
Endocytosis and exocytosis are examples of bulk transport mechanisms in cells. The endocytosis vs exocytosis differences and similarities will be discussed in this article. These bulk transport mechanisms are used to move materials into or out of the cell. The processes function in transporting molecules and substances that are too large to …
Endocytosis is an example of a bulk transport mechanism used by some cell types. The endocytosis process and steps involve the transportation of molecules into the cell by engulfing it with the cell membrane. Cells need to eat and drink but have a cell membrane that protects them. Some substances such as …
Centrosomes are sites where protein dimers assemble into microtubules in a cell. These organelles function in the regulation of cell cycle progression and the formation of mitotic spindles. Centrosomes definition in biology The centrosome is the primary microtubule-organizing center (MTOC), regulating cell adhesion, motility, and polarity. The centrosome is composed of two …
