Title or Heading / Turn It into a Question / Read to Answer The QuestionCell Energy / Why do organisms need energy? / Organisms need energy to allow them to live, grow and reproduce.
From Sun to Cell / Almost all of the energy on earth comes from the ______. / Almost all of the energy on earth comes from the sun.
What is photosynthesis? / Photosynthesis is the process by which CO2 and H2O and light energy are converted into glucose and oxygen.
Photosynthesis / In what organelle does photosynthesis take place? / Photosynthesis takes place in a cells chloroplasts.
What three things are needed for photosynthesis? / 1. H2O
2. light energy
3. CO2
What two things are produced by photosynthesis? / 1. glucose
2. oxygen
Getting Energy from Food / How do animals get energy from food? / All animals get energy from food by
breaking down food molecules to release stored energy.
What are two ways organisms can break down food molecules to get energy? / 1. cellular respiration
2. fermentation
What is the major difference between cellular respiration and fermentation? / Cellular respiration requires oxygen to produce energy while fermentation produces energy without oxygen.
Cellular Respiration / In what organelle does cellular respiration take place? / Cellular respiration takes place in a cells mitochondria.
What two things are needed for cellular respiration? / 1. glucose
2. oxygen
What three things are produced by cellular respiration? / 1. H2O
2. ATP (energy)
3. CO2
Photosynthesis and Respiration: What’s the Connection? / How is photosynthesis different from cellular respiration? / Photosynthesis takes place in chloroplasts and produces glucose, water and oxygen. Cellular respiration takes place in mitochondria and produces water, carbon dioxide, and ATP (energy).
Fermentation / Sometimes your muscle cells can’t get the oxygen they need to produce energy through cellular respiration so instead they produce a smaller amount of energy through a process called fermentation. Fermentation occurs in the absence of oxygen and causes the buildup of lactic acid which causes your muscles to be sore. / Sometimes your muscle cells can’t get the oxygen they need to produce energy through cellular respiration so instead they produce a smaller amount of energy through a process called fermentation.
