Respiration is process where plant produce heat
Explanation:
Respiration is essential component for every living thing this. Respiration help living thing get energy and stay alive. In plant cellular respiration is used to convert nutrient which is present in soil and this process can be understand as a cellular activity. In plants seeds play vital role.
The basic difference between respiration and photosynthesis is in respiration plant consume nutrient for survival and alive plant cell but in photosynthesis plant is able to make their own food. In respiration only plant produce heat energy
<u>The formula of Respiration:
</u>
Oxygen + glucose – Carbon dioxide + water + heat energy
<u>The formula of Photosynthesis
</u>
Carbon dioxide + Water + Sunlight – Oxygen + glucose
