Biodiversity Practical 1

The correct phylum for mixed diatoms is Phylum Chrysophyta. It is important to differentiate between different phyla and their characteristics in order to correctly identify organisms.

Amoeba belongs to the Phylum Rhizopodia, which consists of amoeboid protozoa characterized by temporary extensions of their cytoplasm known as pseudopods.

African Sleeping Sickness is caused by Trypanosoma, which falls under the Phylum Sarcomastigophora. The other options listed are responsible for different diseases such as Schistosomiasis, Lymphatic filariasis, and Malaria.

Trichomonas, a genus in the Phylum Sarcomastigophora, is the causative agent of trichomoniasis, a sexually transmitted infection.

Spirogyra belongs to the phylum Chlorophyta, which consists of green algae. It is a filamentous green algae commonly found in freshwater habitats.

The Phylum Basidiomycota consists of various fungi, with mushrooms and ganoderma applanatum being specific examples. Lions, tigers, apple trees, oak trees, snakes, and lizards do not belong to this particular phylum.

Saccharomyces cerevisae belongs to the phylum Ascomycota due to its characteristic budding reproduction and formation of ascospores.

Phylum Ascomycota includes a wide variety of fungi with Penicillium and Aspergillus being common examples. Rhizopus and Saccharomyces belong to different phyla, Agaricus and Trichoderma are from Phylum Basidiomycota, and Mucor and Candida are from Phylum Zygomycota and Phylum Deuteromycota respectively.

Peziza Reponda belongs to Phylum Ascomycota, which is a large and diverse phylum of fungi known as sac fungi.

Euglena belongs to the Phylum Euglenophyta, specifically the genus Euglena. The other incorrect options are not related to Euglena and belong to different phyla in the plant kingdom.

Paramecium is a single-celled organism belonging to the phylum Ciliophora, known for its characteristic cilia and unique feeding mechanisms.

Malaria is caused by the protozoan parasite Plasmodium, belonging to the Phylum Apicomplexa.

Lichens are symbiotic organisms composed of a fungus and either algae or cyanobacteria. They come in three main types: Crustose (crusty), Foliose (leafy), and Fruticose (shrub-like).

Phylum Chlorophyta consists of green algae, with Volvox being a colonial organism belonging to this phylum. Amoeba is a unicellular organism from the Kingdom Protista. Euglena is a single-celled organism that can act as both plant-like autotrophs and animal-like heterotrophs. Diatom is a type of unicellular algae known for their silica exoskeletons.

Phylum Phaeophyta consists of brown algae, such as Fucus and Sargassum. The incorrect answers provided do not belong to this particular phylum and are not examples of organisms within Phaeophyta.

Peridinium belongs to the phylum Pyrrophyta, also known as Dinoflagellates. These organisms are characterized by two flagella and a unique cell covering called a theca.

Streptococcus Pyogenes is the bacterium that is primarily responsible for causing strep throat, while the other options are associated with different types of infections.

Proteus Vulgaris is a common bacterium known to cause urinary tract infections. While E. coli is another common culprit, Staphylococcus aureus and Pseudomonas aeruginosa are less likely to be associated with UTIs.

Gonorrhea is caused by the bacterium Neisseria Gonorrhoeae. While other sexually transmitted infections such as Chlamydia trachomatis, Treponema pallidum, and Mycoplasma genitalium can cause similar symptoms, they are not the primary causative agent of gonorrhea.

Staphylococcus Aureus is a bacterium commonly found on the skin and in the nose of healthy individuals. It is known to cause food poisoning when contaminated food is consumed. E. coli, Salmonella, and Listeria are also common causes of foodborne illnesses, but in this case, Staphylococcus Aureus is the correct answer.

Syphilis is primarily caused by the bacterium Treponema Pallidum. Staphylococcus Aureus, Escherichia Coli, and Clostridium Botulinum are not associated with syphilis.

Nostoc is a type of cyanobacteria that forms colonies of cells, known as 'beads', which look like a string of pearls. Chlorella, Spirulina, and Anabaena are also types of algae but do not exhibit this specific characteristic.

An oscillator is a circuit that generates a continuous, repetitive electronic signal, typically a sine wave or a square wave. Transistors, resistors, and capacitors do not perform the function of generating such electronic signals.

Pseudomonas Aeruginosa is a Gram-negative bacteria known for its resistance to many antibiotics and its ability to cause infections in hospitalized patients. While E. coli, Staphylococcus aureus, and Clostridium difficile are also common bacteria, they are not as frequently associated with infections contracted in healthcare settings.
