Question

What is an experiment to demonstrate cellular respiration?

Answer 1

Measure `CO_2` or `O_2` in closed systems

Explanation:

One dark bottle and one transparent bottle (both contain the same plant (exactly same amounts) are left to the ambient circumstances.

You can measure either `CO_2` or `O_2` in these closed bottles to see cellular respiration in a full day.

Similar experiment is designed for aquatic plants.
