Group 4 is made up of algae whose chloroplasts are surrounded by a double membrane of chloroplast E.R. This group is also called Chromista. Compared to the other groups, this one has the most subgroups (phyla), which include the following:

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:

The chloroplast envelope is made up of two membranes that wrap around the chloroplasts of eukaryotic algae. The three phyla that make up this group are:

Algae are hard to put into groups, and the way they are put into groups has changed many times over the years. Different parts of the organisms have also been used to come up with different systems. In this section, we’ll show how algae can be divided into four main groups. These things are:

The history of phycology as a field of study can be broken down into four main periods.
