| Rhodophytes, like glaucophytes, lack chlorophyll b but carry a complement of phycobilins arranged in phycobilisomes on unstacked thylakoids. |
| There are more than 5200 species of rhodophytes, and although some rhodophytes do inhabit fresh water, red algae are most common in tropical marine environments. |
| These reef-building rhodophytes are called coralline algae, because they secrete a hard shell of carbonate around themselves, in much the same way that corals do. |
| In Asia, rhodophytes are important sources of food, such as nori. |
| For two important groups, rhodophytes and stramenopiles, we combined more distantly related taxa, since the monophyly of these groups has not been questioned. |
| This is with the addition of eight chlorophytes, one chrysophyte, two phaeophytes and five rhodophytes. |
