  • They mostly live in warmer marine waters.
  • The thallus is usually multicellular and some even have complex organization.
  • Cell wall contains cellulose and pectin along with phycocolloids and carrageenan.
  • They have chlorophyll a and d. 
  • The red colour is due to R-Phycoerythrin. 
  • It also has a phycocyanin. 
  • Due to the presence of Phycoerythrin they can grow in deep waters where other algae cannot grow.
