Question

Which characteristics do all Protista have in common?

Answer 1

Unicellular and lack of cell specialization is a common feature of all the Protista.

Further Explanation:

Protists produce generally by the means of sexual reproduction. They undergo in meiosis that is a reductional division and produce haploid cell. Protists are deliberated as first eukaryotes to be recognized. They are unlike from prokaryotes as they have a distinct cytoskeleton. They also comprises of different organelles and nuclear covering. Protists have a diverse range of cell surfaces and can easily survive in any unfavorable environment because of the presence of outer cover. They have “Flagella” for the propulsion. They can be either autotroph or heterotrophs as they ingest food by pulling them in the “intra-cellular vesicles” denoted as phagosomes or vacuoles. They can yield by the means of sexual and asexual process. Protista produces through meiosis, which is a “reductional division” causing the materialization of haploid cells. The progeny produced by the merger of two haploid cells allows the formation of new allelic grouping by genetic recombination.

Answer 2

Protists are eukaryotic organisms that cannot be classified as a plant, animal or fungus. They are mostly unicellular, but others like algae are multicellular. Protists have mitochondria responsible for respiration to produce energy to be used by cells. Additionally, they can be parasites and mostly prefer aquatic or moist environments. They may be classified as animal-like protists (heterotrophs and have ability to move), Plant-like (autotrophs that photosynthesize) and fungi-like (heterotrophs with cells that have cell wall and reproduce by spore forming). Protists reproduce by asexual means (e.g. budding) or sexually. Therefore, in this case we may conclude that they are all parasites and reproduce sexually or asexually.
