Lysosome
Explanation;
-Lysosomes are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.
-Each lysosome is surrounded by a membrane that maintains an acidic environment within the interior via a proton pump. They contain digestive enzymes (acid hydrolases). They digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria, by breaking down macromolecules such as nucleic acids, proteins, and polysaccharides.
Plants’ nonspecific immune responses includes cell-surface receptors (pattern recognition proteins) which allow them to identify certain patterns characteristic for pathogens. Activated receptors trigger the production of chemical signals that may initiate both local and systemic defense responses. Sometimes when a plant is affected by infection, it triggers rapid localized programmed cell death to stop the infection further. When it comes to defense form the herbivores, plants have physical barriers (plant cell walls and their extensions), some antibiotic compounds (phytoalexins), and even enzymes that can defend them.
