Plants also do respiration
We know
that during daylight (or artificial light, except green) plants carry out
photosynthesis and release OXYGEN. Like
animals, plants also require energy to live and grow. This energy comes
from glucose during respiration. Respiration uses oxygen and give up
carbon dioxide. To demonstrate this, we can do the following: Diagram of
enclosed plant and related graph! The graph
shows that the level of oxygen rises in the daytime. This is due to photosynthesis producing more oxygen than the plant's respiration
using it up. The level of oxygen falls during night due to the plant's
respiration using it up and no more is being produced as there is no
photosynthesis happening. The amount of oxygen rises
gradually, over the period of time. The level of
CO2 falls during day time due to photosynthesis using it
up. However, it rises at night because of respiration. On the whole
the level of CO2 falls since the plant use up more CO2 than it produces.
