Protozoa

The cell membrane of euglenas is composed of a lipid bilayer embedded with protein channels and receptors. It is flexible and helps regulate the passage of molecules in and out of the cell. The membrane also contains specialized structures called pellicles which provide structural support and allow for flexibility and movement.

Amoeba is animal-like because they can not do photosynthesis which other plant-like protists can do. Amoeba are protozoans. Amoeba hunt for their food. They eat bacteria, smaller protozoans and other smaller organisms.

The light sensing organ in Euglena is called the light-sensitive eyespot or stigma. It helps the organism detect changes in light intensity and direction, allowing it to move towards light sources for photosynthesis.

Both the euglena and trypanosome are flagellated protozoans that have a similar cell structure with a single flagellum used for movement. They both possess a unique organelle called the kinetoplast, which is involved in the synthesis of RNA and DNA. Additionally, both organisms can switch between different energy sources, such as photosynthesis and aerobic respiration in the case of euglena, and glycolysis and oxidative phosphorylation in the case of Trypanosomes.

A Paramecium has an elongated oval or slipper-like shape with a pointed anterior end and a rounded posterior end. It is typically covered in cilia that help with movement and feeding.

exists in colonies.

Entamoeba histolytica is found worldwide, with higher prevalence in tropical and subtropical regions with poor sanitation and hygiene practices. It is commonly found in areas with overcrowding, inadequate sanitation, and limited access to clean water. Infections are more common in developing countries.

Paramecium bursaria primarily feeds on algae, which it ingests through a structure called the cytostome. They can also engage in mutualistic relationships with the algae by harboring them within its cells and benefiting from their photosynthetic activity.

Some protozoans can be dangerous to humans, such as those that cause diseases like malaria and Giardiasis. However, not all protozoans are harmful, and many play important roles in ecosystems as part of the food chain.

Protozoa that move by means of a whiplike organ called a flagellum are known as flagellates. The flagellum propels the organism through its environment by waving back and forth, allowing it to swim and navigate through water. Flagellates can be found in a variety of environments, including freshwater, marine, and soil habitats.

Non-motile protozoa rely on external forces for movement, such as water currents or host organisms. These protozoa typically lack structures like flagella or pseudopods that enable independent movement. Instead, they may adapt by attaching to a surface or living as parasites within a host.

Yes, euglenas are capable of photosynthesis, so they can make their own food using sunlight, carbon dioxide, and water. Additionally, they can also absorb nutrients from their environment when sunlight is not available.

Amoebas help humans by playing a role in breaking down organic matter in the environment, which helps in the recycling of nutrients. They also serve as food sources for various organisms in aquatic ecosystems, contributing to the overall food web. However, some species of amoebas can also cause diseases in humans if ingested or come into contact with open wounds.

Euglena, as a genus of unicellular flagellate protists, have three methods of nutrition. The first is holozic, which is the ingestion of solid food. The second is saprophytic. This is the absorption of foods. The last is holophytic which uses chemical elements for foods.

False. Protozoa are not part of the Plant kingdom, they are classified in the Kingdom Protista.

Conjugation in Paramecium is important for genetic diversity. It allows for the exchange of genetic material between individuals, leading to new genetic combinations and variations in the population. This genetic diversity can increase the chances of survival and adaptation to changing environments.

Food is stored in food vacuoles within an amoeba. When an amoeba engulfs food particles through phagocytosis, the food vacuole forms around the ingested material. Enzymes then break down the food inside the vacuole for digestion.

Amoebas were discovered in 1757 by August Johann Rösel von Rosenhof, a German naturalist. He observed and described them in his work "Insecten-Belustigung" as tiny creatures with constantly changing shapes.

Pretty sure its paramecium (phyla - ciliophora)

Their shells are the most complex and have an outer layer called a pellicle that contains defense structures called trichocysts. (just reading it from my textbook)

Amoebas are found in the phylum Protozoa within the kingdom Protista. They are commonly found in freshwater environments, soil, and marine habitats. Amoebas are known for their ability to move and feed by extending their cell membrane.

Paramecium utilizes a process called diffusion to respire. Oxygen enters through the cell membrane, while waste products like carbon dioxide exit the cell through the same process. This allows Paramecium to exchange gases with its environment and maintain its metabolic functions.

Correct, a pellicle is not found on amoeba. Amoebas are single-celled organisms that do not possess a fixed structure like a pellicle, which is a tightly packed layer of proteins just beneath the cell membrane found in some other types of single-celled organisms.

Protozoa that move by hairlike projections are known as ciliates. They have numerous hair-like structures called cilia that beat in a coordinated manner to propel the organism through its environment. Ciliates are found in various aquatic habitats and are known for their complex behaviors and feeding strategies.
