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 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
Spirogyra Definition Spirogyra DefinitionSpirogyra is a green alga that occurs mainly in fresh water in the form of lumps. These are also known as water silk or mermaid braids. It is a unicellular organism, but it can be seen in freshwater bodies when it agglomerates into a multicellular structure. Spirogyra is composed of chlorophyll, which gives it … Read more
What is the function of the nucleoid? Definition of nucleoid Definition of nucleoid What is the function of the nucleoid? Definition of nucleoidThe nucleoid is the site inside a prokaryotic cell where genetic information is found, called a genophore. Prokaryotes are divided into bacteria and archaea, which are single-celled organisms without membrane-bound organelles. There is … Read more
What is the respiratory system? What is the respiratory system?Every organism needs oxygen to survive because oxygen provides energy by oxidizing or decomposing organic food substances, this process of oxidation of food substances is called respiration. In other words, it can be said that the oxidation process that takes place in living organisms, in which there … Read more
Predation Definition Predation DefinitionPredation is a type of ecological interaction in which one species kills another and feeds on it. The organism that kills the dead organism and feeds on it is called the predator, while the killed organism is called the Predation. Hunting is different from catching dead organisms, but predators also start as … Read more
Zygote Define Zygote DefineThe zygote is a fertilized egg cell. Germ cells go through meiosis, are in the haploid stage (s) as part of spermatogenesis and oogenesis. The sperm and thus the unfertilized egg cell restore a set of chromosomes in the zygote during a diploid stage (2n). The cellular mechanisms present in the gametes … Read more
What does golgi apparatus do? Definition, Overview Definition of the Golgi apparatus What does Golgi Apparatus do?The Golgi apparatus is an organelle in eukaryotic organisms that transports molecules from the endoplasmic reticulum to their destination. The organelle also modifies the products of the endoplasmic reticulum in its final form. The Golgi apparatus consists of a … Read more
What is Pituitary Gland? What is Pituitary Gland?The pituitary gland is an endocrine gland that serves to maintain cellular homeostasis in the body by releasing various hormones. The pituitary gland is also known as the master gland because it controls the work and secretion of other endocrine glands. Although the main endocrine gland, the pituitary … Read more
What is Pancreas? What is Pancreas?The pancreas is a complex organ made up of both exocrine and endocrine regions, with the endocrine part being made up of discrete islets of Langerhans that secrete several hormones. The involvement of cells in diabetes has increased over the years in studies of Langerhans Island. Islets, which consist of … Read more
