  1. Write a word equation that describes the process of photosynthesis.   (1 mark)
  2. Outline the distribution and uses of photosynthetic products in plants.   (3 marks)

a.   
           

b.   Glucose:

  • The primary product of photosynthesis is glucose, which can be transported via the phloem to other parts of the plant, such as roots, fruits, or growing tissues. 
  • Alternatively, it can be converted to starch for short-term storage in leaves or transported to roots or other storage organs for long-term storage. 

Oxygen:

  • Oxygen is produced as a byproduct and released into the atmosphere through the stomata, although some is used by the plant for its own cellular respiration processes.

\(B\)

Show Worked Solution
  • In plants, the products of photosynthesis (primarily sugars) are transported from the leaves, where they are produced, to other parts of the plant via the phloem tissue.

\(\Rightarrow B\)
