The hydrolytic enzymes contained within the lysosome allow foreign particles to be destroyed. Lysosomes are only found in animal cells. Lysosome Structure Functions Types Characteristics Yb Study Lysosomes play an important role in phagocytosis. . 1 Lysosomes are membrane enclosed organelles containing enzymes to breakdown all types of biological polymers. Lysosomes are involved with various cell processes. The key function of lysosomes is digestion and removal of waste. One of the key organelles involved in digestion and waste removal is the lysosome. During fertilization the sperm releases hydrolytic enzymes from the acrosome vesicles and digest the membrane of the ovum. They break down excess or worn-out cell parts. When macrophages phagocytose foreign particles they contain them within a phagosome. A lysosome is a membrane-bound cell organelle that contains digestive enzymes. And soma body thus helping...
