The Kingdom Protista was thought to be evolved 1.5 billion years ago through endosymbiosis. The Kingdom Protista contains life-forms similar to those that gave rise to the three kingdoms of multicellular organisms-fungi, plants, and animals.
Mushroomes
Phytoplankton refers to a broad category of organisms. Many belong to the kingdom Protista, and some belong to the kingdom Monera. They are all microscopic organisms that are capable of undergoing photosynthesis. Phytoplankton, or phytoplankton-like organisms are believed to be responsible for the Earth's first mass extinction, as their waste product, oxygen was suddenly released into the early atmosphere, which acted as a poison to early organisms that was used to the abundant sulfur in the atmosphere.
There are several groups, including the reds (which include many seaweeds, including the coralline algae), greens (that include both marine, aquatic and terrestrial species, and are related to land plants), and the browns (which also include many seaweeds, including kelp). They are in the protista kingdom. They were first in the plantae kingdom and have moved a lot and been disputed about, but they have been decided to be in the protista kingdom.

The first eukaryotes are most likely to belong to the Protista kingdom. These are mostly multicellular organisms with the earlier ones including organisms like Kneallhazia solenopsae and many more.
when multicellular algae included in kingdom protista than it will converted into the protoctista

Probably Protista, because there are evidences that suggests they were the first eukaryotes to be developed.
First of all, Protista is a kingdom, not a phylum. But there are over 24 Phyla in this kingdom. What makes protists different from other kingdoms is that they are unicellular, have a nucleus in their cells, they have no cell wall,, and they can be hetertrophs or autotrophs.
Scientists believe that animals evolved from single-celled organisms in the oceans around 600 million years ago, making them the first to appear. Plants, on the other hand, evolved from ancient algae and appeared on land around 450 million years ago.
vertebrates and invertebrates
There are six kingdoms: Kingdom Animalia Kingdom Plantae Kingdom Protista Kingdom Fungi Kingdom Archaebacteria Kingdom Eubacteria The first four are eukaryotes and the last two are prokaryotes. It might be the other way around though.
Prokaryote organisms, such as blue algae, are believed to be the first organisms to have evolved through photosynthesis about 3 and a half billion years ago.
