I thought oxygen was a by-product or waste which the plant excretes after photosynthesis the combination of CO2 + H2O = C6H12O6 + O2 So wouldn't it be a combination of sunlight, carbon dioxide, and water to produce a sugar  or glucose molecule and oxygen which it expires during transpiration.

Hello Professor McIntyre,

I was wondering what the "2n" and "n" represent on the mosses slide.

Also, the "Ferns" slide is blurry and I wanted to understand what the stage is called between:
1. the mature sporophyte and spores,
2. spores and prethallus (gametophyte), and
3. prethallus and female/male gametes.

also, what do those words mean?

thanks.
