These are the vacuoles or sac like* to modify and package proteins for exportstructures. They occupy a considerablehave cis and trans faceamount of cytoplasm.stacks of flattened sacs vacuole^ plant - few/largeanimal - small
fluid-filled sacs^ * Vacuoles are pouches in the cell that store materials suchas water, salts, proteins, and carbohydrates, waste productsand toxic waste..store food, water, waste (plants need to store large amountsof food) Vesicles^ A lot of small bubble sacs inanimals, large sac in themiddle of plant cells
These are small-sized sac like*These help in storage and release of substances as requiredstructures. They are of different typesby the cell. For example lysosomes help in cell digestionlysosomes, peroxisomes.when cell dies. Vacuoles function is to store water. lysosome^ plant - uncommonanimal - common
*small, round, with a membrane^ breaks down larger food molecules into smaller moleculesdigests old cell parts chloroplast^ plant, not animal^
