Answer: Oxygen gas is produced during photosynthesis.
Photosynthesis takes place in the chloroplasts or in the green leaf. The colour of the leaves is due to the various pigments like Chlorophyll a (bright or blue-green in the chromatogram), chlorophyll b (yellow-green), xanthophylls (yellow), and carotenoids (yellow to yellow-orange). However, chlorophyll is the main pigment required for photosynthesis.
Factors affecting Photosynthesis
Photosynthesis is affected by the following factors:
Light affects photosynthesis hence it is important to distinguish between light quality, light intensity, and the duration of exposure to light.
It is affected by carbon dioxide.
There should be an optimum temperature for photosynthesis. It depends on the habitat that plants are adapted to.
Water affects photosynthesis as water stress makes leaves wilt and causes the stomata to close.
Which gas is produced during photosynthesis?
Out of the given options, Oxygen is the correct answer.
