Digestive Enzymes Serves as the pathway for the transport of materials and information around the cell Endoplasmic Reticulum List the 3 main ideas behind the cell theory 1. All organisms are made of cell 2. The cell is the basic unit of organization 3. All cells come from preexisting cells The site of protein synthesis Ribosome The small membrane bound structures in a cell Organelles The breakdown of molecules in order to release energy occurs here. Mitochondria What organelle do animals cells have that plants cells do not? Centrioles / Centrosome Name the plastid responsible for the Color of flowers, fruit, and leaves in the fall Chromoplasts A cell moves particles from a region of greater concentration to a region of lesser concentration by….. Diffusion What type of passive transport uses a carrier protein to pass across the cell membrane? Facilitated Diffusion Why does active transport require energy to get across the plasma membrane? Goes against concentration gradient http://www.biologie.uni-hamburg.de/bonline/library/biology107/bi107vc/fa99/ter ry/images/ATPpumA.gif The difference in concentrations between a region of high concentration and low concentration is called ….. Concentration gradient Compare and contrast active transport and facilitated diffusion. Compare: both transport substances across the membrane via a protein Contrast: Active – energy required, against gradient Facilitated – no energy, with gradient When there is no net movement of water across the membrane, we can conclude that the cell is in a(n)_____ Isotonic Solution Water moves out of a cell if the cell is placed in a(n) _________ solution Hypertonic Water moves into a cell if the cell is placed in a(n) _______ solution. Hypotonic If a cell is placed in salt water, water leaves the cell by…. Osmosis What would happen to animal and plant cells placed in hypotonic and hypertonic solutions? The process of transporting materials into a cell by means of a vesicle? Endocytosis The process of transporting materials out of the cell is called? Exocytosis When small amts of liquids enter the cell by endocytosis it is called____. Pinocytosis When solid particles enter the cell by endocytosis it is call _____. Phagocytosis What is the difference between a prokaryotic and eukaryotic cell? Prokaryotic – no nucleus and membrane bound organelles Eukaryotic – nucleus and organelles
