Protozoa
Bacteria are prokaryotic cells; fungi, protozoa, algae, plants, and animals are composed of eukaryotic cells. 7. Viruses are not cells so they are neither prokaryotic nor eukaryotic. They can replicate only inside a living cell.
Are protozoa prokaryotic or Eukaryotic?
Unicellular eukaryotic organisms – these organisms are unicellular and are eukaryotes. They have membrane bound true nucleus and other membrane bound organelles. These are mainly free living or aquatic parasites like the protozoans, some fungi and algae or some protists.
Are Protozoa unicellular or multicellular?
In 21st-century systems of biological classification, the Protozoa are defined as a diverse group of unicellular eukaryotic organisms.[1] Historically, protozoa were defined as single-celled animals or organisms with animal-like behaviors, such as motility and predation.
What is one way Protozoa can be classified?
Sarcodine, any protozoan of the superclass (sometimes class or subphylum) Sarcodina. These organisms have streaming cytoplasm and use temporary cytoplasmic extensions called pseudopodia in locomotion (called amoeboid movement) and feeding.
What type of locomotion does phylum sarcodina use?
The ciliates are a group of protozoans characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but are in general shorter and present in much larger numbers, with a different undulating pattern than flagella.
What type of locomotion does phylum ciliophora use?
Zooflagellates move by whip like flagella
What type of locomotion does phylum zoomastigina use?
All Sporozoa have a cellular structure known as apical complex, which gave origin to the name of the Phylum, i.e., Apicomplexa. Sporozoa cellular organization consists of the apical complex, micropore, longitudinal microtubular cytoskeleton, and cortical alveoli.
What type of locomotion does phylum sporozoa use?
1. Protozoa (animal-like protists) are heterotrophs that ingest or absorb their food and helps. 2. Algae (plant-like protists) are autotrophs they get nutrition from photosythesis.
Are Protozoa autotrophic or heterotrophic?
The most common form of asexual reproduction used by protozoa is binary fission. In binary fission, the organism duplicates its cell parts and then divides itself into two separate organisms. Two other forms of asexual reproduction used by protozoa are called budding and schizogony.
Can all Protozoa reproduce asexually or sexually?
Protozoa are one-celled animals found worldwide in most habitats. Most species are free living, but all higher animals are infected with one or more species of protozoa. Infections range from asymptomatic to life threatening, depending on the species and strain of the parasite and the resistance of the host.
Do protozoans have tissue differentiation?
