Explanation:

1. Eukaryotic cells have various small structures called organelles which perform different functions. Nucleotides are building - blocks of nucleic acids, not the general small structures in cells.
2. Lysosomes break down waste materials and cellular debris in the cell, similar to how the stomach breaks down food in the body. The heart is a muscular organ for pumping blood and has no similar function to lysosomes.
3. Vacuoles in cells mainly store water, maintaining turgor pressure and other functions. While they can store some sugars, their primary function is water - storage.
