- What aspect of photosynthesis is being tested in the above diagram?
- Represent the process of photosynthesis in the form of a balanced equation.
- Why was the plant kept in the dark before beginning the experiment?
- What will be the result of the starch test performed on Leaf ‘A’ shown in the diagram? Give an example of a plant with variegated leaves
- Draw a neat labelled diagram of a chloroplast.
Name the following:
The kind of plastids found in the mesophyll cells of the leaf.
Most leaves have the upper surface more green and shiny than the lower one. Why?
State one important function of chloroplasts.
Differentiate Between:
Stroma of chloroplast and Grana of chloroplast
