Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the biochemical pathway?Involves chloroplasts, peroxisomes, and mitochondria, with RuBisCO playing a central role
2. What is the primary function?Dissipates excess light energy, prevents photodamage, and salvages carbon lost during oxygenation
3. Why do plants need chlororespiration?Plants use chlororespiration to protect their photosynthesis machinery when there is too much light or not enough carbon dioxide. It helps prevent damage and keeps the plant growing.
4. How does chlororespiration protect plants from too much light?When light is very bright, chlororespiration helps get rid of excess energy by using oxygen and releasing carbon dioxide. This stops the plant from getting burned by the light.

RuBisCO: Ribulose-1,5-bisphosphate carboxylase/oxygenase, a key enzyme in photosynthesis that can also react with oxygen.
Photodamage: Damage to biological tissues caused by light, particularly excessive or high-energy light.
C3 Plants: Plants that perform photosynthesis using the Calvin cycle, where the first product is a three-carbon compound.
