Figure 1 shows some of the products and reactants involved in photosynthesis.
Draw lines to show the following:
- Which substances are the reactants of photosynthesis and which chemical formulae are used to represent these reactants.
- Which substances are the products of photosynthesis and which chemical formulae are used to represent these products.
Where would a land-based plant obtain the reactants of photosynthesis named in part (a)?
Photosynthesis is described as an endothermic reaction because it uses energy transferred from the environment to the chloroplasts in the leaves of the plant.
Name where the energy comes from to drive photosynthesis.
Figure 2 shows a plant cell with three cellular components labelled.
Identify which of the following options gives the correct name and function of P, Q and R.
P | Q | R | |
A | Chloroplast - stores water | Cytoplasm - where chemical reactions take place | Vacuole - stores water |
B | Vacuole - the site of photosynthesis | Chloroplast - stores water | Cytoplasm - where chemical reactions take place |
C | Vacuole - stores water | Cytoplasm - where the chemical reactions take place | Chloroplast - the site of photosynthesis |
D | Chloroplast - the site of photosynthesis | Cytoplasm - where chemical reactions take place | Vacuole - stores water |
