Detailed explanation-1: -Both mitochondria and chloroplasts contain their own DNA and ribosomes.

Detailed explanation-2: -Photosynthetic protists have chloroplasts and are capable of photosynthesis, although not all use the same chloroplast pigments and they often have different chloroplast structure. Heterotrophic protists require organic chemicals from their environment.

Detailed explanation-3: -Protists also have mitochondria, which are the organelles responsible for turning food into energy the cell can use. Photosynthetic protist cells also have chloroplasts, or the organelles that are able to capture the energy from sunlight and turn it into sugars.

Detailed explanation-4: -Photosynthetic lineages can be found across the phylogenetic tree of protists. Most of the groups are unrelated to each other, as each major lineage acquired its chloroplast (and therefore the ability to photosynthesize) from different endosymbiotic events.
