internal membrane system found in eukaryotic cells

organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell

cell organelle that stores materials such as water, salts, proteins, and carbohydrates

cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell

strong, supporting layer around the cell membrane in some cells

network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement
