GENERAL HISTOLOGY

Detailed explanation-1: -The lysosome is a specialized vacuole that stores digestive enzymes.

Detailed explanation-2: -Almost all plant cells have large vacuoles that contain both hydrolytic enzymes and a variety of defense proteins.

Detailed explanation-3: -Different types of cell vacuoles store different substances, such as alkaloids, protein enzymes, inorganic salts, sugars, etc., and play important roles in multiple signaling pathways.

Detailed explanation-4: -Our data support the hypothesis that the central vacuole of higher plant cells has an enzyme composition analogous to that of the animal lysosome. None of the vacuolar enzymes investigated was found to be bound to the tonoplast.
