40 Cell Anatomy Cell Cell membrane Cytoplasm Organelle
41 Cell Anatomy Cell Fundamental unit of all living organisms and the simplest form of life, that can exist as a self-sustaining unit.
42 Cell Anatomy Cell membrane Semi-permeable membrane that separates cytoplasm from the surrounding external environment. Governs exchange of nutrients and waste materials.
43 Cell Anatomy Cytoplasm Gel-like fluid within the cell membrane in which organelles float. Provides cellular nutrition and supports organelles.
44 Cell Anatomy Organelle Cellular structures that possess distinct structures and functions. The organs of a cell.
45 Let s draw what we know!
46 Cell Anatomy Nucleus Control center of the cell. Directs nearly all metabolic activities. Contains DNA and RNA.
47 Cell Anatomy Ribosome Synthesizes proteins.
48 Cell Anatomy Mitochondrion (p. mitochondria) Power plant of the cell. Responsible for cellular respiration. Provides most of the cell's ATP.
49 Cell Anatomy Lysosome Engulfs and digests bacteria, cellular debris and other organelles.

52 Fill in the Blanks 1. Nucleus = control center 2. Ribosome = synthesizes proteins. 3. Mitochondrion = power plant 4. Lysosome = engulf and digest.
53 Cell Physiology Adenosine triphosphate Passive cell process Active cell process
54 Cell Physiology Adenosine triphosphate (AKA: ATP) The body s energy storage molecule.
55 Cell Physiology Passive cell process Diffusion Filtration Osmosis Active cell process Active transport pumps Active transport vesicles
56 Cell Physiology Passive cell process Movement of substances across the cell membrane by means of pressure and concentration without the expenditure of ATP. Types: diffusion, filtration, and osmosis.
57 Cell Physiology Diffusion Movement of molecules from an area of higher concentration to an area of lower concentration, a process that continues until the distribution of particulates is equal in all areas.
58 Cell Physiology Diffusion Movement of molecules from an area of higher concentration to an area of lower concentration, a process that continues until the distribution of particulates is equal in all areas.
59 Cell Physiology Filtration Movement of particulates across the cellular membrane as a result of pressure.
60 Cell Physiology Osmosis Movement of a pure solvent such as water from an area of low concentration (most dilute) to an area of high concentration (least dilute). Movement continues until the two concentrations are equal.
61 Cell Physiology Active cell process Movement of substances across the cell membrane that requires the expenditure of ATP.
62 Cell Physiology Active transport pumps Carrier proteins that are part of a cell membrane attract charged particles (ions) and move them from one side of the cell membrane to the other. Example: sodium-potassium pump used during nerve conduction.
63 Cell Physiology Active transport vesicles Small spherical sacs that transport various substances within a cell, as well as import and export materials into and out of the cell.
64 Cell Physiology Phagocytosis Process by which specialized cells ingest harmful microorganisms and cellular debris, break them down, and expel the harmless remains back into the body. Pinocytosis Process by which specialized cells engulf liquids and draw them into the cell.
65 Compare and Contrast Passive Cell Process! Movement across cell membrane Active Cell Process! Movement across cell membrane! Free! Costs ATP! Diffusion! Filtration! Osmosis! Phagocytosis! Pinocytosis
66 Cellular Metabolism Metabolism Anabolism Catabolism
67 Cellular Metabolism Metabolism The total of all physical and chemical processes that occur in an organism. Examples: Anabolism The constructive phase of metabolism in which smaller, simpler molecules are built up into larger molecules. Catabolism The destructive phase of metabolism in which larger, more complex molecules are converted to smaller, simpler molecules.
68
69 Catapults are destructive and so is Catabolism
