What is a word equation for photosynthesis? | …
The figure illustrates how closely photosynthesis and respiration are linked. As you can see, thanks to these two life-sustaining processes, plants and animals depend on each other to survive.
What is a word equation for photosynthesis
Only plants can photosynthesize, but both plants and animals depend on respiration to release the chemical potential energy originally captured through photosynthesis.
A lot of my college students still have trouble with this one. The reactions that happen in respiration and photosynthesis are different, but if we just look at what goes in and what comes out, they're opposites.
Carbon dioxide (CO2) and Water (H20) in, Oxygen and Sugar out.
Requires energy from the sun.
Here's cellular respiration:
Oxygen and Sugar in, CO2 and H20 out. Releases energy from the sugar.
Plants can do both. When they have light, they use it as an energy source to put the pieces of CO2 and H2O to make sugar. They can put a bunch of sugars together to make starch (what foods are starchy?), cellulose (the stringy stuff you can't chew up), and wood.
When it's dark, they can do cellular respiration to break down the starch and sugar to release the energy they need.
Poor animals, we can only do cellular respiration. We need foods like starch, and oxygen, and we breathe out the CO2 that's made. We don't get enough water from the process to take care of all of our needs so we have to drink more. Kangaroo rats don't have to drink water. They conserve water a lot better than we do.
Can plants live without animals? Can animals live without plants?
Thanks for asking.
Chemistry for Biologists: Photosynthesis
Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product.

The Light Reactions(4.1) In the chemical reaction for photosynthesis, six molecules of water and six molecules of carbon dioxide react in the presence of chlorophyll and sunlight to produce one molecule of sugar plus six molecules of oxygen.

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.
