Question

select all the correct answers.
according to the theory of endosymbiosis, early eukaryotes evolved by symbiotic association of prokaryotes. which two protists evolved from a symbiotic relationship of organisms, which resulted in eukaryotic organisms containing chloroplasts?
paramecium
red algae
euglena
slime molds

Explanation:

Euglena and red algae are protists that contain chloroplasts. Euglena has chloroplasts and can perform photosynthesis. Red algae also have chloroplasts which are involved in photosynthesis. Slime molds are amoeba - like and do not have chloroplasts for photosynthesis in the context of endosymbiosis - related chloroplast origin. Paramecium is a ciliate and does not have chloroplasts (it is heterotrophic, mainly feeding on bacteria etc. and not having chloroplasts from the endosymbiotic origin as described in the question).

Answer:

Euglena, Red algae
