What is exocytosis? Exocytosis mechanism

What is exocytosis? As compared to endocytosis, exocytosis is a process that is used to use energy to move materials from inside the cell to the outside of the cell. Therefore, it is a kind of active transport mechanism and the opposite of endocytosis. Generally, in this exocytosis mechanism, a special vesicle attached to the cell … Read more

Definition of Endocytosis, and Process of Endocytosis

Definition of Endocytosis  Endocytosis is a cellular mechanism by which a cell internalizes substances such as proteins, fluids, electrolytes, microorganisms, and certain macromolecules from its external environment. These substances are subjected to certain processes of decomposition into smaller elements, either for use by the cell or for elimination. White blood cells of the immune system … Read more

What is a eukaryotic cell? Eukaryotic cells (from the Greek word Eukaryota, the union of EU – “true” and karyon “nut, nucleus”) are called all cells in whose cytoplasm a precisely defined nucleus can be found that contains most of their genetic material (DNA ).

What is Cytosol? | Definition of cytosol

What is Cytosol? |Definition of cytosol Cytosol can be defined as the cytosol is the fluid inside the cells. It is the water-based solution in which organelles, proteins, and other cellular structures float. The cytosol in any cell is a complex solution, whose properties allow the functions of life to take place. The cytosol contains proteins, amino acids, mRNA, … Read more

Plant Cells and Animal Cells-Differences and Comparisons, and Diagram

Plant Cells and Animal Cells-Differences and Comparisons, and Diagram

Animal cells and plant cells have several differences and similarities. For example, animal cells do not have cell walls or chloroplasts, while plant cells do. Animal cells are mostly round and irregular shapes, while plant cells have a fixed rectangular shape. Animal and plant cells are eukaryotic cells, so they have some common features, such … Read more

What are bacteria? Types, Structure, Examples, and viruses/bacteria

What are bacteria? Bacteria are a large group of prokaryotic microorganisms (without nuclei) with various possible shapes and sizes. Although all prokaryotic organisms used to be grouped under the term “bacteria”, today they are divided into two categories in taxonomy: the bacterial domain and the archaeal domain. Both are summarized in the Prokaryota Superkingdom, which … Read more
