Protists are classified borganisms that do not fit into the other group classification i.e. fungi, plant, animal and bacteria.

However, organisms in the group called PROTISTS can either be animal-like or plant-like depending on whether they possess some animal or plant characteristics respectively. Plant-like protist, like the organism described in the question, have CHLOROPLAST organelles like plants and hence, can perform photosynthesis in the presence of sunlight to synthesize their own food. This characteristics makes them autotrophic like plants.

Therefore, based on the characteristics of the new specimen collected from a deep jungle survey, the classification that fits it best is PLANT-LIKE PROTISTS.
