If you put Hydrilla plant in a beaker having pond water and an inverted test tube filled with water inserting the twig of hydrilla, and keep it in sunlight; the air bubbles start comimng out and stored in the test tube. The liberated gas is tested as oxygen. This means the hydrilla plant is photosynthesizing.
Another experiment is done by testing the presence of starch in a plant by iodine test.

∙ 12y agoI order to know if photosynthesis has taken place, you need to know whether it has made it's own food (glucose) by adding iodine to one sample of a leaf. If it turned black, then it has glucose in it, if brown, then no glucose in it. Then you need to find if it has stored starch. That's what you find and if you found the answer please continue on this and explain in more.

∙ 14y agowhen the process of photosynthesis takes place then glucose is formed as a product. then , this glucose only is stored in the plants in the form of starch in leaves , stems , etc. parts of the plant.
therefore , to determine whether photosynthesis has taken place or not the presence of starch can be tested in a plant by an experiment.

chloroplasts
Is the cell of the cortex where photosynthesis take place?
no , photosynthesis is taken place in chloroplast which contain chlorophyll. hope it helps xxx sorry if it doesn't <3 xx
From where does the oxygen liberated in photosynthesis come?
If you mean where is the oxygen released when photosynthesis has taken place then the answer is the stoma which is located under the leaf
Where does the energy in biodiesel come from?
The energy comes from the plants because photosynthesis is being taken place
What goes on in chloroplast?
Photosynthesis is taken place. It produces glucose and oxygen
What liquid is taken up in photosynthesis?
Water is taken in and utilized by plants for photosynthesis.
Photosynthesis is taken in by?
Photosynthesis isn't taken in by anything. Photosynthesis is an act that plants go through to turn light energy into food.
What will happen if nitrogen fixation does not take place?
if nitrogen fixation does not take place nitrates will not be taken if nitrates are not there so there is no photosynthesis so it metaboills and if photosynthesis is not there so there is no life thats what nitrogen fixation not allows in nitrogen cycle
Where does photosynthesis take place globally?
Photosynthesis take place globally in the leaves.Leaves only carry out photosynthesis.
Is energy taken in photosynthesis?
Energy is absorbed by photosynthesis. This energy is stored in glucose
What part of the plant does photosynthesis happen?
photosynthesis takes place in the leaves of a plant.
