2. The Cell Cycle
Sketch each step in the cell cycle process in the circles provided on the concept map.

3. 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 dioxide

5. 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

6. 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
