Biology Ii Protists Quiz

Green Plant-like Algae, also known as Chlorophyta, fits the description provided due to being multi-cellular, aquatic, photosynthetic, and having protoplasmic threads.

Diatoms are classified as Plant-Like Protists, they obtain energy through Photosynthesis, are typically found in Marine and freshwater environments, and are made of SiO2 (Silicon dioxide + organic matrix).

This question tests knowledge of the characteristics and significance of different types of algae. The correct answer provides detailed information about Red Algae, including its phylum, cellular nature, energy source, reproduction method, habitat, 'root' structure name, and commercial and medical significance. The incorrect answers provide information about other types of algae, highlighting their differences in characteristics and significance.

Euglenas belong to the phylum Euglenophyta, and they can be found in freshwater environments. They are unicellular organisms.

Slime molds belong to the phylum Myxomycota, are multicellular but multinucleate, obtain energy from decomposing organisms, reproduce sexually through fruiting bodies and spores, and are commonly found on the forest floor.

Each of the incorrect answers provided are examples of different protists with distinct characteristics, phylum, mode of locomotion, reproduction, and habitat. By comparing them to the correct answer which describes an Amoeba, it becomes evident why they are not the correct match for the given question.

Foraminiferans are unicellular organisms that have a shell composed of calcium carbonate. They are mainly found in aquatic and marine environments and play a significant geological role in forming limestone.

The correct answer is Radiolarians, which are part of the phylum Actinopoda, unicellular, and get energy by eating. They are found in marine environments, have an endoskeleton made of silicon dioxide, and use stiff pseudopods for locomotion. Radiolarians are significant in correlating the age of geological strata.

Giardia Intestinalis belongs to the phylum Zoomastigophora, which is known for flagellated protists with modified mitochondria called mitosomes.

The correct answer is Trypanosoma brucei, as it is a flagellated protist that is a unicellular parasite found in the blood or tsetse fly/kissing bug. It gets its energy from its kinetoplast and mitochondrial DNA. The incorrect answers provide information about different microorganisms with varying characteristics, but they do not match the description provided in the question.

Trichomonas vaginalis belongs to the phylum Zoomastigophora, which is known for its unique characteristics.

Trichonympha belongs to the phylum Zoomastigophora and can be found in the gut of termites where it aids in digesting cellulose, making it uniquely suited for this environment.

The correct answer is Paramecium, as it is a unicellular organism belonging to the phylum Ciliophora. It is capable of both sexual and asexual reproduction and can be found in freshwater environments. Paramecium has a unique band extending along the length of the cell beneath the plasma membrane and possesses both macro and micro nuclei.

Gymnodium is a zoomastigophoran overall and is also photosynthetic, which places it in the phylum Pyrrophyta.

Spirogyra is a type of green algae belonging to the phylum Chlorophyta. It is a multicellular organism that obtains its energy through photosynthesis. It can reproduce sexually through conjugation and can be found in freshwater environments. Protoplasts are protuberances of protoplasm that form a conjugation tube during sexual reproduction in Spirogyra.

Ich, also known as Ichthyophthirius multifiliis, is a common and highly contagious parasitic infection affecting fish in freshwater ecosystems. It is characterized by white spots on the fish's skin and can be fatal if left untreated.

Phylum apicomplexa organisms are unique in that they are all obligate parasites, meaning they cannot survive without a host.

The correct answer is Plasmodium (organism), Apicomlexa (phylum), Ring stage (stage), 1 (number of the stage).

The correct answer refers to the organism Plasmodium, belonging to the phylum Apicomplexa. The specific stage mentioned is Band stage, with a number indicating it as stage 2. The incorrect answers provided are not related to the given question details.

The correct answer is Plasmodium in the phylum Apicomplexa at the developing schizont stage 3. The incorrect answers either reference different organisms, phylum, stages, or incorrect numbering.

Plasmodium belongs to the phylum Apicomplexa. It is a parasitic protozoan known to cause malaria in humans.

The correct answer refers to the organism Plasmodium belonging to the phylum Apicomplexa in the stage of gametocyte, which is the fourth stage of its life cycle.

The correct answer describes a Cellular slime mold belonging to the phylum Acrasiomycota, being multicellular and obtaining its energy through decomposition. It reproduces both sexually and asexually through fruiting bodies that produce spores, and can be found in soil.
