Cell Transport & Cell Organelles Review

1. Place the following into either active or passive transport Passive Transport Does not require energy Molecules move from high to low concentrations diffusion osmosis Active Transport endocytosis exocytosis Requires energy Molecules moves from low concentration to high concentration 2. Match the type of transport with the appropriate definition Osmosis The diffusion of water from high to low Diffusion Moving molecules from high to low concentration without energy Active Transport Using energy to move molecules from low to high concentration Cell Membrane Controls what enters and leaves the cell 3. Which cell organelle is MOST responsible for helping the cell maintain homeostasis by diffusion? mitochondria nucleus cell membrane cell wall 4. Homeostasis is necessary for a cell to survive. What is the definition of homeostasis? elimination of wastes division of cells maintenance of a stable internal environment process by which energy from the sun is used to make food 12. Cell Organelle Matching Match the organelles with the correct definitions. Chloroplast In plant cells, allows photosynthesis to occur Mitochondria In plant and animal cells, allows respiration to occur Cell Wall In plant cells, provides structure for the plant Ribosomes In plant and animal cells, creates proteins Nucleus In plant and animal cells, control center of the cell
