WebQuick look: Golgi apparatus (or complex, or body, or ‘the ‘Golgi’) is found in all plant and animal cells and is the term given to groups of flattened disc-like structures located close to the endoplasmic reticulum. The number of ‘Golgi apparatus’ within a cell is variable. Animal cells tend to have fewer and larger Golgi apparatus. WebJul 30, 2024 · Organelles allow for various functions to occur in the cell at the same time. Despite their fundamental similarities, there are some striking differences between animal and plant cells (see Figure 1). Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts ...
Cell damage (also known as cell injury) is a variety of changes of stress that a cell suffers due to external as well as internal environmental changes. Amongst other causes, this can be due to physical, chemical, infectious, biological, nutritional or immunological factors. Cell damage can be reversible or irreversible. Depending on the extent of injury, the cellular response may be adaptive and where possible, homeostasis is restored. Cell death occurs when the severity of the injury ex… WebMay 4, 2024 · DNA, the heredity information of cells, which can be found in a nucleus of eukaryotic cells and the a nucleoid region of prokaryotic cell. 4. ribosomes, or protein-synthesizing structures composed of ribosomes …
