Question

I will mark you brainliest please no spam I have a test tomorrow - what is the evidence that plants take in CO2 for photosynthesis, or how can we do an experiment to prove this?

Answer 1

plants take carbon dioxide nd also sun light to perform photosynthesis.
They do thiss process with their leaves mostly.
In leaf there is a structure named as stomata
it will performs a crucial role to synthesis carbon dioxide.
it will opens and close to absorb carbon dioxide and also to release of oxygen
There is a expirement to prove that plants take carbon dioxide for photosynthesis
take a potted healthy plant nd kept in a dark place for 2 to 3 days before the experiment
Take glass bottle with a potassium hydroxide solution it will absorb carbon dioxide remained in the bottle
place the bottle to a potted plant healthy leaf half leaf into the bottle and remaining will be outside
Nd make sure that no air will be entered into that bottle
Place it in the sun light for 2 to 3 hours
Now cut the leaf from the potted plant nd dip into the iodine.
The part that exposed with carbon dioxide and sunlight will turn into blue the remaining part of the leaf where stay normal
