Do only GREEN plants produce oxygen? ?

Question

do plants such as the Cordyline red fountain (google that) produce the s

Answer 1

No

Your red plant still has green chlorophyll that does the photosynthesis that produces oxygen. Red pigments in the cell wall hide the green color.

Primitive cells that lack chlorophyll produce poisonous hydrogen sulphide gas (ie the slime around hot springs)

ps did you know that chlorophyll and hemoglobin in our blood are very similar chemically - chlorine gives chlorophyll its green color, iron the red color of blood. After all we evolved from plant life!

Answer 2

Yes, it's only green plants cos it's only green plants who perform photosynthesis and photosynthesis alone produces oxygen as a by-product
