Which characteristics do all protista have in common? they are all autotrophic and mobile. they are all heterotrophic and produce spores. they are all parasites and reproduce sexually or asexually. they are all unicellular and lack cell specialization.

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.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
