| Dark | Respiration but no photosynthesis | Oxygen taken in, carbon dioxide given out |
| Dim light | Photosynthesis rate equals respiration rate | Neither gas is taken in or given out |
| Bright light | Photosynthesis rate greater than respiration rate | Carbon dioxide taken in, oxygen given out |
Photosynthesis and respiration in plants
Plant cells respire, just as animal cells do. If they stop respiring, they will die. Remember that respiration is not the same as breathing, so take care - plants do not breathe.
Here is the word equation for aerobic respiration:
glucose + oxygen → carbon dioxide + water
Here is the word equation for photosynthesis:
carbon dioxide + water → glucose + oxygen
The word equations show that the reactants and products of aerobic respiration and photosynthesis are opposites:
Plants respire all the time, whether it is dark or light. They photosynthesise only when they are in the light.
- aerobic respiration uses oxygen and produces carbon dioxide
- photosynthesis uses carbon dioxide and produces oxygen
Dark Respiration but no photosynthesis Oxygen taken in, carbon dioxide given out Dim light Photosynthesis rate equals respiration rate Neither gas is taken in or given out Bright light Photosynthesis rate greater than respiration rate Carbon dioxide taken in, oxygen given out
Hapo vumbi vipi?Mimea inasaidia kuleta hewa safi tunayoihitaji kwa afya zetu. Uharibifu wa mazingira unaongezeka hasa mijini.
Hii picha inaonyesha unavyoweza kujiongeza na kupata hewa safi hasa wakati ukiwa umepumzika.

huwa naogopa nyoka tu. kingine, unajua mimea usiku inavuta hewa ya oxygen, mchana carbondioxide. hivyo usiku mtakuwa mnagombania hako kaoxygen chumbani kwako na mimea.Mimea inasaidia kuleta hewa safi tunayoihitaji kwa afya zetu. Uharibifu wa mazingira unaongezeka hasa mijini.
