Which structure is found in both plant and animal cells?

• cell walls

• mitochondria

• chloroplasts

• centrioles

Which of the following describes cell membrane composition?

• cell membranes are composed of carbohydrates, which allow all materials to enter and leave the cell

• cell membranes are composed of lipid molecules, which provide a flexible structure

• cell membranes are composed of cytoplasm, which allows proteins to be excreted by the cell
