Group 3

This group of algae has a single chloroplast E.R membrane that surrounds the chlorophyll. This group is also called Rhizaria. It is made up of two phyla, which are:

• Euglenophyta – Euglenids are flagellates that live in fresh water and have both chlorophyll a and chlorophyll b. They also have strips of protein-filled pellicle underneath the plasma membrane.
• Dinophyta – Dinophyta is a type of seaweed that is usually green (however, they can also be found in freshwater). They also have the chlorophylls a and b and eat bacteria and other small protists in their environment. Chlorarachniophytes have flagella, just like Euglenids. But some of them look like amoebas.
• Apicomplexa – This group is mostly made up of parasitic alveolates that have a complex structure at the top of their cells called an apicoplast. This is a key part of the organisms that lets them get into the host and make it sick.
