All living things need energy to carry out their life processes
All Living Things Need ENERGY Only in Plants Need Sunlight Plants Photosynthesis Cellular Respiration Only in Plants Need Sunlight Plants at Night Animals 24/7
The ability to do work or cause change ENERGY The ability to do work or cause change
How do living things get energy? By burning fuel Cars burn gasoline (non-living)
How do living organisms get energy? Living organisms “burn” glucose (simple sugar) This is called CELLULAR RESPIRATION
Where does glucose come from? Animals ingest food Carbohydrates
Where does glucose come from? Plants are different Plants make their own food in a process called PHOTOSYNTHESIS
Food making process in plants and other organisms that use sunlight PHOTOSYNTHESIS Food making process in plants and other organisms that use sunlight
Only occurs when light is shining on the plant PHOTOSYNTHESIS Only in plants Only occurs when light is shining on the plant At night, plants use cellular respiration for energy

Chloroplasts and Photosynthesis
Photosynthesis takes place in the (leaves / root) of a plant. (Sunlight / Water) supplies the energy a plant needs to make sugar. Carbon dioxide enters the plant through the (xylem / stomata). The cell parts of green plants where photosynthesis takes place are (mesophyll / chloroplasts). A plant gives off (oxygen / carbon dioxide) as a byproduct during photosynthesis. Water is taken into a plant through the (roots / veins). An organism that gets food by eating other organisms is (an autotroph / a heterotroph).
Cellular Respiration A chemical reaction that takes place in the mitochondria This reaction releases energy for the cell to use

Cellular Respiration Equation C6H12O6
What are the byproducts of cellular respiration? C6H12O6 + 6O2 6CO2 + 6H2O + ENERGY Glucose + Oxygen Carbon dioxide + Water + ENERGY What are the byproducts of cellular respiration? Answer: Carbon dioxide, water and ENERGY! What sugar is used for cellular respiration? Answer: glucose
Why does the body carry out cellular respiration? C6H12O6 + 6O2 6CO2 + 6H2O + ENERGY Glucose + Oxygen Carbon dioxide + Water + ENERGY Why does the body carry out cellular respiration? Answer: to produce energy What substances does the body need to carry out cellular respiration? Answer: oxygen and glucose
