mitochondria

Which organelles help cells produce storage vacuoles?

golgi apparatus

Which structures carry out internal cellular movement?

microtubules and microfilaments

Which organelle would you expect to find in plant cells but not animal cells?

chromoplast

Which of the following is the most vital function of the cell membrane?

regulates which materials enter and leave the cell

The cell membrane contains channels and pumps that help move materials from one side to the other. What are these channels and pumps made of?

proteins

Diffusion occurs because

molecules constantly move and collide with each other

Which means of particle transport requires input of energy from the cell?

pinocytosis

The diffusion of water across a selectively permeable membrane is called

osmosis

cell, tissue, organ, organ system

The process of getting large food particles into a cell is called:

phagocytosis

What is an example of passive transport?

facilitated diffusion

Which of the following would add pigments such as red & yellow to plant cells?

chromoplasts

What purpose do structures such as glycoproteins and carbohydrates attached to phospholipids serve?

they give a cell better structure to attach to other tissue parts in the body

Which of the following is representative of isotonic solutions?

both water levels and all solutes are at equilibrium
