Hypothesis Testing
The lack of chlorophyll in kidney beans is due to the environment. Presence of chlorophyll in plants
Chlorophyll is a green pigment found in the cyanobacteria and the chloroplasts of algae and plants. Chlorophyll is an extremely important biomolecule critical in photosynthesis, allowing plants to absorb energy from lights. Chlorophyll is present in specialised cells within plants and many algae, when sunlight is present, chlorophyll combines it with water and carbon dioxide and creates energy through photosynthesis, a bi-product of which is oxygen. Organism that can photosynthesise are called autotrophs or “self-feeders”. Chlorophyll in leaves enables plants to trap light energy; it traps sunlight energy for the plants and begins the process of photosynthesis. It gives plants the greenish colour that mo st plants contain. It also helps to make food for the plants. Hypothesis:

Is the lack of chlorophyll due to the plants genotype or phenotype to the environment? Materials Used:
400 mustard seeds

Put another plate in a dark cupboard.
Water the seeds daily and record the results that are viewed. Data was collected on annual recording of the plants growth and change in colour. I then recorded the plant growth and colour change on a line graph
