Dictionary » L » Lysosome LysosomeDefinition noun, plural: lysosomes Organelles containing a large range of digestive enzymes used primarily for digestion and removal of excess or worn-out organelles, food particles, and engulfed viruses or bacteria.
Their specific functions include digestion of macromolecules from phagocytosis, endocytosis, and autophagy, digestion of bacteria and other waste materials, repair of damage to the plasma membrane by acting as a membrane patch, and apoptosis (e.g. digesting web from the fingers of a 3- to 6-month-old fetus). Often, they are referred to as “suicide-bags” because of their role in autolysis. Lysosomes were discovered by the Belgian cytologist Christian de Duve in 1949.
Related forms: lysosomal (adjective).

Somehow this did not follow through and there was a power struggle, as most of the mitochondrial ...

Bio Application Problem... My answer: Enzymes can be very harmful if allowed to freely diffuse through the cytoplasm, if lysosomal enzymes are let loose through the lysosome, it would disolve many vital molecules and ions that are present in the cytoplasm, and may even disolve the plasma membrane, which could lead ...

About LysosomesWell some consider vacuoles and lysosomes the same organelle, some consider them different organelles. They evolved from the same ancestor and are related in many ways, that is sure. Personally I have nothing against considering the vacuole ...

About LysosomesSo we can consider there is not the same organelle as lysosome in plant cells. Same function but different organelle. In plant cells they are food vacuoles. To be or not to be that isn't a question. Definition is the question.
