Standard 2 Describe cell processes necessary for achieving homeostasis, including active and passive transport, osmosis, diffusion, exocytosis and endocytosis. By: Desaree Jackson
Homeostasis • Maintaining a constant internal environment. • Sweating is one way the body tries to achieve homeostasis. By: Desaree Jackson
Cellular Transport • Passive transport: requires no energy • Diffusion: compounds move from high to low concentration • Osmosis: diffusion of water • Hypotonic solutions cause water to move into the cell so the cell swells up • Hypertonic solutions cause water to move out of the cell so the cell shrivels up • Isotonic solutions cause no net movement of water into or out of the cell • Active transport: requires energy • Endocytosis: large compound are brought into the cell • Exocytosis: large compounds are exported out of the cell By: Desaree Jackson

Diffusion By: Desaree Jackson
Standard 3 Identify reactants and products associated with photosynthesis and cellular respiration, and the purposes of these two processes. By: Desaree Jackson
Photosynthesis • Process by which organisms use energy from sunlight to make their own food (glucose) • Glucose is a simple sugar • Photosynthesis occurs in the chloroplasts of plant cells and some bacteria • Chloroplasts have a green pigment called chlorophyll • Steps of photosynthesis • 1. Light reaction: chlorophyll in the chloroplasts absorbs sunlight • 2. Dark reaction: The energy from the sunlight is used to make glucose • Light energy is completely changed into chemical energy (glucose) • Chemical equation for photosynthesis • 6CO2 + 6H2O + light energy C6H12O6 + O2 By: Desaree Jackson
Cellular Respiration • Process that breaks down glucose in order to make energy for an organism • ATP: compound that stores energy in an organism • Occurs in the mitochondria of the cell • Two types of cellular respiration • Aerobic respiration: requires oxygen to occur • Mostly happens in animals and plants By: Desaree Jackson
Photosynthesis Plants * use sunlight to make glucose * take in carbon dioxide * give off oxygen *carbon dioxide + water + sunlight glucose + oxygen *6CO2 + 6H2O + light energy C6H12O6 + 6O2 • Respiration • Animals and plants • * eat plants to get glucose • * take in oxygen • * give off carbon dioxide • *glucose + oxygen carbon dioxide + water + ATP • C6H12O6 + 6O2 6CO2 + 6H2O + chemical energy Graphic Organizer By: Desaree Jackson
