It is not just animals that – plants carry out respiration as well. Plants respire all the time because their cells need energy to stay alive, but plants can only photosynthesise when they are in the light.
Photosynthesis and respiration worksheets for kids.
While photosynthesis is performed by most plants which can prepare their own food, most animals fulfill their energy requirements through cellular respiration.
Photosynthesis is the process by which plant cells convert light energy from the sun into chemical energy, so as to create energy-rich carbohydrate molecules like glucose.
Cellular respiration is the process of breaking down food molecules to obtain energy and store it in the form of adenosine triphosphate (ATP) molecules.
Plant cells, after creating sugar molecules through photosynthesis, undergo cellular respiration to create ATP molecules.
