Organelle. In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive. Organelles are either separately enclosed within their own lipid ...
Stanford Online High School, also known as Stanford OHS, SOHS, or OHS and formerly known as EPGY Online High School, is an online independent school located within Stanford University for academically talented students worldwide. It operates as a six-year school, serving students in grades 7–12. The current Head of School is Tomohiro Hoshi.
Organelle biogenesis. Organelle biogenesis is the biogenesis, or creation, of cellular organelles in cells. Organelle biogenesis includes the process by which cellular organelles are split between daughter cells during mitosis; this process is called organelle inheritance. [1]
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
Cell mechanics is a sub-field of biophysics that focuses on the mechanical properties and behavior of living cells and how it relates to cell function. [1] It encompasses aspects of cell biophysics , biomechanics , soft matter physics and rheology , mechanobiology and cell biology .
The cytoskeleton consists of (a) microtubules, (b) microfilaments, and (c) intermediate filaments. [ 1] The cytoskeleton is a complex, dynamic network of interlinking protein filaments present in the cytoplasm of all cells, including those of bacteria and archaea. [ 2] In eukaryotes, it extends from the cell nucleus to the cell membrane and is ...
The cell cycle, or cell-division cycle, is the sequential series of events that take place in a cell that causes it to divide into two daughter cells. These events include the growth of the cell, duplication of its DNA ( DNA replication ) and some of its organelles , and subsequently the partitioning of its cytoplasm, chromosomes and other ...
Lysosome. Centrosome. Cell membrane. A lysosome ( / ˈlaɪsəˌsoʊm /) is a single membrane-bound organelle found in many animal cells. [ 1][ 2] They are spherical vesicles that contain hydrolytic enzymes that digest many kinds of biomolecules. A lysosome has a specific composition, of both its membrane proteins and its lumenal proteins.
