    • Photosynthesis and respiration are an important scientific topics which are in the curriculum of many countries. Because of the importance and the difficulty of the subjects, it is important to determine university students’ misconceptions. Thus, it is emphasized in many studies that one of the reasons for misconceptions of students is the teachers. Students were asked to draw what is photosynthesis and respiration in plants on a blank piece of A4-sized paper.
  • 4. These misconceptions can stem from education students received in the university. Studies made in Turkey, emphasized that the lecturers in education faculties use the lecture method of drawing and the students graduate from the education faculties without being introduced with any other alternative instruction methods. Thirty two percent of the students leave the respiration in plants subject blank answer and 58% of them have misconceptions. These students concentrate on the misconceptions.
  • 5. Misconceptions such as “Respiration occurs in no plant cells; While respiration in green plants is the taking in of CO2 and giving off of O2 during the day, it is taking in of O2 and giving off of CO2 at night”
  • 6. Respiration occurs in plants cells , Respiration in plants occurs only at a day and night, Respiration in plants is a gaseous exchange process during which O2 is taken in and CO2 is given off, Respiration in plants takes place solely in the leaves”
  • 7.
    • The truth about respiration
    • Glucose + Oxygen = Carbon Dioxide + Water + Energy
  • 8. The example of the corrected misconception drawing by the student Plants not only use sunlight to live and grow but also water and suitable environment to live
  • 9. MISCONCEPTION CORRECT THE MISCONCEPTION
    • Plants use CO2 to carry out respiration and to produce O2.
    • The plants release energy, using up food and oxygen and producing carbon dioxide during respiration process.
    • Humans are giving off CO2 in respiration; plants are giving off O2 in respiration.
    • Both human and plant give off CO2 during respiration.
    • While respiration in green plants is the taking in of CO2 and giving off of O2 during the day,it is taking in of O2 and giving off of CO2 at night.
    • Respiration in plants is always occurring in plants; that is to say, plants are continuously taking in oxygen and giving off carbon dioxide and water in the mitochondria. 
  • 10. MISCONCEPTION CORRECT THE MISCONCEPTION
    • Respiration in plants is a gaseous exchange process during which O2 is taken in and CO2 is given off,
    • Respiration in plants is the taking in of CO2 and giving off of O2 at night .
    • Respiration in plant is a biochemical process that harnesses glucose and oxygen to provide ATP for metabolic function
    • Plants photosynthesize and animals respire.
    • Both plants and animals can respire in term of cellular respiration.
    • Plants use sunlight to live and grow.
    • Sunlight is the one basic needed of plant to grow and live.
  • 11. MISCONCEPTION CORRECT THE MISCONCEPTION
    • Respiration in plants does not take place in the presence light energy.
    • Respiration in plants can take place in the presence light energy (photorespiration).
    • Respiration in plants occurs only at night.
    • Respiration in plants occur all the times.
    • Respiration in plants occurs only in their store roots.
    •  
    • Respiration in plants occurs in all the part include leaves and stem.
