Photosynthesis and Respiration

Jacob Caldwell and Isaac Oesterling

Photosynthesis

  • The main path for water movement in photosynthesis is from soil to roots. It moves through the root paths to get to the leaves.
  • CO2 diffuses through small holes in the leaf called stomata to help in the process of photosynthesis.
  • Photosynthesis takes place inside plant cells in small plastids called chloroplasts that contain chlorophyll a green pigment used for capturing sunlight
  • The radiant energy captured by the chlorophyll converts CO2 and H2O into carbs.
  • The waste produced is oxygen and it is removed by exiting the stomata.
  • Plants use sugar for energy storage and growth.
  • The final products of photosynthesis are glucose and oxygen, it is important to us because we need the oxygen produced to breathe.

Cellular respiration

  • The main site of cellular respiration in the cell is the mitochondria.
  • Glucose enters the body through food that you eat.
  • Oxygen enters the cell through small air sacs called alveoli, leading to the lungs, and then it enters the blood stream.
  • The product of cellular respiration is ATP, ATP is adenosine triphosphate, a nucleoside triphosphate that is used to transport chemical energy within cells.
  • ATP is important because it is the main source of free energy in living organisms.
  • The waste product of cellular respiration is Carbon Dioxide.
  • All living things must carry out cellular respiration.
