Respiration in Plants Class 11 Notes - Chapter 14

Do Plants Breathe?

Plants, just like most other organisms on earth, use oxygen, and as a result, plants breathe. However, they don’t breathe as most animals do, as plants do not have organs dedicated to the process of gaseous exchange. Instead, they have organelles called stomata and lenticels for this purpose.

Respiration in Plants

Plants perform photosynthesis to create sugars (such as glucose), this, along with oxygen is used to produce energy which is used in the plant’s growth. This process of respiration is essentially the process of photosynthesis but in reverse.
