3. In two groups, the eukaryotic nature of the endosymbiont can be seen by its retention of a vestige of a nucleus (called its Nucleomorph). A group of unicellular, motile algae called cryptomonads appear to be the evolutionary outcome of a nonphotosynthetic eukaryotic flagellate (i.e., a protozoan) engulfing a red alga by endocytosis.

NUCLEOMORPH
Nucleomorphs are small, vestigial eukaryotic nuclei found between the inner and outer pairs of membranes in certain plastids.
Nucleomorphs represent some of the smallest genomes ever sequenced. After the red or green alga was engulfed by a cryptomonad or chlorarachniophyte, respectively, its genome was reduced. The nucleomorph genomes of both cryptomonads and chlorarachniophytes converged upon a similar size from larger genomes.
They are thought to be vestiges of primitive red and green algal nuclei that were engulfed by a larger eukaryote. Because the nucleomorph lies between two sets of membranes, nucleomorphs support the endosymbiotic theory and are evidence that the plastids containing them are complex plastids.
The nucleomorph genomes of both cryptomonads and chlorarachniophytes converged upon a similar size from larger genomes. They retained only three chromosomes and many genes were transferred to the nucleus of the host cell, while others were lost entirely.
