Lysosomes are organelles that contain enzymes. Which of the following is a function of lysosomes?

• Lysosomes build lipids, carbohydrates, and proteins.

• Lysosomes package lipids, carbohydrates and proteins.

• Lysosomes break down lipids, carbohydrates, and proteins.

• Lysosomes store lipids, carbohydrates, and proteins.

Which of the following structures are present in both plant and animal cells?

• cell walls

• centrioles

• chloroplasts

• mitochondria

All cells contain cell membranes. Which of the following describes the composition of cell membranes?

• Cell membranes are composed of carbohydrate chains, which allow all materials to enter and leave the cell.

• Cell membranes are composed of cellulose, which provide rigidity for the cell.

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

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

Which organelles allow plants to support heavy structures such as leaves and flowers?

• The cell membranes because they regulate what enters and leaves the cells.

• The chloroplasts because they convert sunlight into chemical energy.

• The Golgi apparatus because it packages proteins for storage in the cells.

• The vacuoles because they are filled with fluid, which provide rigidity.

In eukaryotic cells, a number of organelles allow the cell to produce and distribute proteins. Where are proteins modified, sorted and packaged?

• Golgi apparatus

• ribosomes

• rough endoplasmic reticulum

• smooth endoplasmic reticulum
