是否所有藻類都可進行光合作用?

唔係.



有d藻係後來失去左葉綠素, 變成進食其他藻類. 例如夜光藻.Noctiluca sp.

These cells are very large, from 1 to 2 millimetres in diameter, and are filled with large buoyant vacuoles. Some may contain symbiotic green algae, but there are no chloroplasts. Instead, they feed on other plankton, and there is usually a special tentacle involved in ingestion.
