Question
How do we know that respiration occurs in plants?
✓
Answer
→ Plants, like all living organisms, require energy to perform various functions necessary for growth and survival.
→ Although plants produce their own food through photosynthesis, they cannot directly use the energy stored in glucose.
→ To access this energy, plants undergo respiration, a process that breaks down glucose in the presence of oxygen to release energy, carbon dioxide, and water.
→ Experimental evidence, such as observing carbon dioxide production in the absence of photosynthesis (e.g., in the dark), confirms that plants respire.
→ This process occurs in all plant parts, both day and night, ensuring a continuous supply of energy for cellular activities.
