Plants do not breathe, they only respire. No such respiratory organ os present in plants. The carbon dioxide produced in animals during respiration is released to the atmosphere, whereas the carbondioxide produced during plant respiration may be used by the plant for carrying out photosynthesis.
Answer;
-Mitochondrion
Explanation;
-A light microscope is an instrument that uses visible light and magnifying lenses to examine small objects not visible to the naked eye, or in finer detail than the naked eye allows.
-Cell organelles that can be seen under light microscope includes; cell membrane, nucleus, nuclear membrane, cytoplasm, vacuoles, cell wall, chloroplasts.
-Mitochondria is an organelle found in the cytoplasm composed of many layers of membrane. site of respiration + production of energy. This is the smallest organelle that can be seen under research grade light microscope.
The Mitochrodria helps break down sugar and turns it into energy
