What is photosynthesis?

Word and chemical equation for photosynthesis

What is the rate of photosynthesis affected by?

The leaves of plants make ............. from carbon dioxide and water using .............. energy from the ......... . This energy is captured by .................. in the ...................... of the leaves and converted to chemical energy in the glucose. ....................... is also produced as a waste product. Glucose is converted into ............... to be transported around the plant and into ............... to be stored.

Glucose made in photosynthesis is used to make:
............ for transport
............ for storage
.................... for cell walls, proteins & DNA
........... as an energy store in seeds
...............
