5. How can you say that plants also respire?
Answers
Answer:
Plants respire through plant pores, called stomata. During respiration and photosynthesis, gases go in and out of the plants through stomata using diffusion, not breathing.
Answer:
Plants do not breathe in the strictest sense of the word. Plants respire through plant pores, called stomata.
During respiration and photosynthesis, gases go in and out of the plants through stomata using diffusion, not breathing
Explanation:
But in everyday lives, we use those words slightly differently because we are not all biologists or chemists.
Respiration in plants is strikingly similar to why living objects breathe.
Living objects breathe because they need to obtain oxygen to carry out cellular respiration to stay alive, just like plants need to respire to stay alive. Then byproducts such as carbon dioxide and water are released and removed from the living objects through breathing, just like plants do when they respire.
Because of these parallel processes, people sometimes imprecisely call respiration in plants as “breathing”.
This is why it is not entirely incorrect if you’re not using this as an answer in exams, but rather, just use it as an analogy. Plants don’t breathe in and out using lungs, but it is an analogy nonetheless.
Oxygen and carbon dioxide pass in and out of the stomata in the plants through diffusion.
When the plant is submerged in the water, bubbles of oxygen or carbon dioxide released are trapped and they stick on the leaves or petals temporarily.
Since these gases are lighter than water, if you shake the plant, the bubbles will quickly rise to the surface and burst. It is similar to you releasing a breath underwater.
