Answer:
It's true
Step-by-step explanation:
Plants use the sun's energy to form organic matter from inorganic matter, a process known as photosynthesis. For other plant activities such as growth, flowering, etc., the chemical energy that comes from cellular respiration is used.
Cellular respiration is a process independent of the presence of sunlight. In this process, oxygen is consumed, and unlike in photosynthesis, where oxygen is released in the sun or light phase.
In photosynthesis, carbon dioxide is consumed and oxygen is released. While oxygen is consumed in cellular respiration and carbon dioxide is released.
