You can conduct investigations to gather evidence for what plants need for photosynthesis
Bromthymol blue is an indicator of carbon dioxide. It changes color in the presence or
absence of carbon dioxide. For a plant to photosynthesize, it needs to take in carbon dioxide
from its environment. Bromthymol blue can indicate this by changing color. Investigations
can also be conducted by placing one plant in the dark and one in the light. You can also
conduct tests to see that oxygen is released in photosynthesis or to explore what factors
can affect the rate of photosynthesis.
