(a) Describe how light energy is converted to chemical energy and stored in carbohydrates in plants.

(b) Suggest how conditions in a glasshouse can be controlled to ensure the maximum
growth of the plants.

A) Photosynthesis is the process by which organisms that contain the pigment chlorophyllconvert light energy intochemical energy which can be storedin the molecular bonds of organic molecules (e.g., sugars). Photosynthesis powers almost all trophic chains and food webs on the Earth.

B) Considering Humidity:

But greenhouses with humidity controls keep the air moist for peakplant growth. Reducing water stress by watering the roots and providing a humid environment allows each plantto concentrate its energy on fruiting and flowering
