If the statement is false, change the italicized term to make the statement true. Write this answer in the blank provided._______________ 5. In passive transport, the movement of particles across a membrane requires energy._______________ 6. Endocytosis is a process by which a cell membrane surrounds and takes in material from the environment._______________ 7. A membrane that allows only some materials to pass through shows selective permeability.Circle the words or phrases that best completes the statement or answers the question. 8. The structure most responsible for maintaining cell homeostasis is thecytoplasmcell wallmitochondriacell membrane9. A cell membrane is made up of a(n)cholesterol layerenzymeslipid bilayerprotein transport molecules10. Which of the following is not a form of passive transport?diffusionendocytosisosmosis11. Diffusion continues until equilibrium is reachedturgor pressure is reachedone side has more12.

A cell moves particles from a region of lesser concentration to a region of higher concentration by diffusion osmosis passive transport active transportUse the pictures on the left to answer the questions on the right.177421103950 = very small glucose molecule00 = very small glucose molecule14.
