The Cell Wall was not present in the first eukaryotes.

Prokaryotes were present for about 2 billion years before eukaryotes emerged. Eukaryotes are believed to have evolved around 1.5 to 2 billion years ago, while prokaryotes first appeared around 3.8 billion years ago.
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.
Most mutations in eukaryotes are recessive because for a mutation to be expressed phenotypically, it typically needs to be present in a homozygous state. In a heterozygous individual, the presence of one normal allele usually masks the effects of the mutated allele, leading to a recessive trait.
Probably Protista, because there are evidences that suggests they were the first eukaryotes to be developed.

Eukaryotes have well defiened cell organali and are bounded by membranes. The DNA in eukaryotes are packed in form of chromosomes which are present in nucleous.

Plastids are organelles and are present in eukaryotes,in plant cells.
Mitochondria is a membrane bound organell.It is found only in eukaryotes.
Proteasomes are protein complexes. These protein complexes are present in eukaryotes, some bacteria and in archaea. The proteasomes are located in the nucleus and the cytoplasm when looking at eukaryotes.
The first eukaryotes were unicellular organisms that evolved around 2 billion years ago, followed by the first terrestrial eukaryotes that emerged around 1.6 billion years ago. Between these events, there were significant biological and environmental changes, including the development of multicellularity and adaptations for life on land.
Prokaryotes are most primitive organisms. All bacteria belong to thiscategory. Eukaryotes are well developed organisms. All animals and Plants including Fungi, Amoeba, Malarial parasite etc belongs to this class. Prokaryotes have single chromosome in there nucleus but eukaryotes have have multiple chromosomes in there nucleus. Prokaryotes do not have His-tone protein present in there Chromosomes. While it is present in Eukaryotes. Nucleolus is absent in bacteria but present in eukaryotes. Nuclearmembrane is absent or poorly developed in Prokaryotes and well developed in Eukaryotes. Cellorganellesare absent or poorly developed in Prokaryotes and well developed in Eukaryotes. Mitochondria are absent in Prokaryotes and present in Eukaryotes. 70S Ribosomes are present in Prokaryotes and 80S and Ribosomes are present in Eukaryotes. Bacteria have cell wall made up of Peptidoglycan (usually.) but plant cell wall is made of cellulose and animal cell do not have it. (pressure inside the gram positive bacteria are 30 times more than atmospheric pressure and that in gram negative bacteria is 5 times more. Itprobablyindicates that gram positive bacteria has originated in deep sea and gram negative in upper part of sea, where pressure is low.
Eukaryotes lack a cell wall made of peptidoglycan, which is present in prokaryotic cells. Additionally, some eukaryotes lack flagella or cilia for motility, which are common in prokaryotic cells.
Major difference, Prokaryotes have no cell nucleus and eukaryotics do. Prokaryotes have been present before eukaryotes. Eukaryotes are thought to have evolved from prokaryotes throught the process of endosymbiosis.
