I did not flatly state that plant cells contain lysosomes because many cell biologists claim that they do not, and it was possible that such a flat statement would be considered an "error" by many teachers. However, there is emerging evidence that, in fact, they do. Here's a paper from the Journal "Plant Cell," pointing out the existence of an organelle in a plant cell that meets every criterion of a lysosome:Here's a passage from the paper:
" The existence of lysosomes in plants has long been debated (see, e.g., Moriyasu and Ohsumi 1996 ). Matile 1975 recognized that catabolic enzymes were essential for sustained biological activity and that these enzymes must be compartmentalized to prevent their indiscriminate hydrolysis of biopolymers. He proposed that plant proteases, nucleases, phosphatases, and other degradative enzymes were constituents of a "lytic compartment," a compartment that included the extracellular space, vacuoles, and other organelles containing lytic enzymes. With improved techniques for vacuole isolation, it became clear that many plant vacuoles contain enzymes found in animal lysosomes (Matile 1978 ; Wink 1993 ). Plant vacuoles were therefore seen as fulfilling the role of the animal lysosomal system (Boller and Wiemken 1986 ). "
Plant cells do not contain lysosomes. Lysosomes are present in the cells of animals, and they are responsible for breaking down waste and other cell debris. According to research from Princeton University, in animals, lysosomes assist the body with digesting nutrients from food. In plants as well as in yeast cells, this job is performed by lytic vacuoles. Lytic vacuoles detoxify plants and maintain overall homeostasis within the cell. Without these parts, a plant would not grow to full maturity. Similarly, without lysosomes, animals would be unable to process food within the body or break down the body's cells after death.They don't need them as the cell wall keeps out large molecules that lysosomes break down.
