What is photosynthesis in biology?

In biology, photosynthesis refers to the process by which plants convert light energy into chemical energy as glucose. It matters because the same idea reappears across many later topics, so building a clear mental picture of it early saves a lot of time.

How to approach it step by step

To work with photosynthesis confidently, follow light-dependent reactions in the thylakoid, then the Calvin cycle in the stroma. LetMeTeach draws this out live on screen while explaining it aloud, so you watch each part appear instead of decoding a static block of text. You can interrupt at any point and ask for the same idea again in simpler words, in another language, or with a different example.

Worked example

6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂.

The mistake most learners make

Saying plants only respire at night, when respiration happens continuously.
