Quiz_Protista

Explanation:Protistan algae, such as diatoms and euglenoids, obtain their food primarily through photosynthesis, using light energy to produce organic compounds.

Explanation:Photosynthetic protists, such as algae, contribute significantly to global photosynthesis, accounting for approximately 50% of the world’s oxygen production.

Explanation:Algae are a diverse group of photosynthetic organisms that can be found in the kingdoms Protista, Monera (cyanobacteria), and Plantae.

Explanation:Physarum is an example of an acellular slime mold, which exists as a large, multinucleate, single cell during its vegetative phase, known as a plasmodium.

Explanation:Slime molds are included in the kingdom Protista because they exhibit characteristics of both fungi and protozoa. They are primarily unicellular and can aggregate to form multicellular structures.

Explanation:Diatoms have a unique cell wall made of silica, known as a frustule, which is composed of two halves that fit together like a petri dish.

Explanation:Photosynthetic protists include euglenoids, diatoms, and dinoflagellates, all of which contain chlorophyll and can perform photosynthesis.

Explanation:In diatoms, the cell size decreases with each division due to the way their silica cell walls are constructed. Each division results in one daughter cell being smaller than the parent cell.

Explanation:Amoeba belongs to the phylum Protozoa, which includes unicellular eukaryotic organisms that are often motile and heterotrophic.

Explanation:Sleeping sickness, also known as African trypanosomiasis, is caused by the protozoan parasite Trypanosoma, which is transmitted by the tsetse fly.
