Which of the following is true about photosynthesis and cellular respiration?

• Photosynthesis is just a reverse equation of cellular respiration.

• Autotrophs and heterotrophs do not need each other to be able to survive.

• Photosynthesis needs glucose and oxygen to produce carbon dioxide, water and energy.

• Cellular respiration needs carbon dioxide, water and energy to produce glucose and oxygen.

Mesophyll layer of the leaf plays an important role in trapping light energy from the sun upon which photosynthesis mostly take place in this layer. Why is this so?

• because it contains air spaces

• because it is transparent allowing light to penetrate

• because it has the greatest number of chloroplasts

• because it provides an entrance and exit for gases
