Which structure is found in some but not all plant cells? vacuole ribosome cell wall lysosome

Lysosome

Explanation:

Lysosomes (from Greek lysis, breakage, destruction) are membrane pockets that contain enzymes capable of digesting organic substances. In general, plant cells do not have lysosomes, but some rare plant species have lysosomes, as do seeds. The role of lysosomes (intracellular digestion) in plants and yeast is played by the cell juice vacuole (tonoplast).
