THE CELL CYCLE • Sketch each step in the cell cycle process in the circles provided on the concept map.

THE ENERGY CYCLE • part of the carbon cycle • producers, consumers • photosynthesis, respiration • chloroplast, mitochondria • photosynthesis produces glucose and oxygen • photosynthesis needs carbon dioxide, water, and sunlight • respiration needs oxygen, glucose, and water • respiration produces energy at ATP and carbon

CELL TRANSPORT • Active Transport • moves materials from low concentrations to high concentrations • requires energy to be completed • two specific types • endocytosis – the use of energy to bring nutrients into the cell • exocytosis – the use of energy to remove wastes from the cell • like plant roots such as potatoes and carrots that continue to absorb more and more water and nutrients

CELL TRANSPORT • Passive Transport • moves materials from high concentrations to low concentrations • happens without energy • two specific types • diffusion – the movement of any molecule from high concentrations to low concentration (like air freshener spreading throughout a room) • osmosis – the movement of water across the cell membrane (like watering a wilted plant) • Continues until balanced • The natural motion of molecules to find equilibrium; an equal rate of flow between the cell and the surroundings
