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.

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

The model shows a substance crossing a cell membrane. Which of the following describes the process?

• The model shows the process of active transport because the solute particles are moving from an area of low concentration to an area of high concentration.

• The model shows the process of bulk transport because the solute particles are moving from an area of low concentration to an area of high concentration.

• The model shows the process of diffusion because solute particles are moving from an area of high concentration to an area of low concentration.

• The model shows the process of osmosis because the solute particles are moving from an area of high concentration to an area of low concentration.
