Protists

The elements that are diatomic in their natural state are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. This means they exist as molecules composed of two atoms when in their elemental form.

Paramecium does not have a respiratory system like humans do. It absorbs oxygen directly from its environment through its cell membrane, and expels carbon dioxide in a similar manner.

Helpful:

●Produce oxygen

●Have an important role in the nitrogen cycle

●Decompose dead organisms

●Help digest food

●Rich in minerals

●Eat bacteria

●Used in medicines

Harmful:

●Red algae- disease causing

Cysts are produced in the resting stage of an amoeba. They are thick-walled structures that protect the amoeba from harsh environmental conditions like drought or lack of nutrients. Cysts allow the amoeba to hibernate until conditions become more favorable for growth and reproduction.

Diatomic elements are elements which consist of two atoms of the same element joined together in their normal elemental state. The diatomic elements are:

hydrogen

oxygen

nitrogen

and the halogens (chlorine, bromine, etc.)

Evidence that Paramecium is living is that they eat, respond to the enviroment, produce waste, reproduce, produce energy, and all of the other characteristics of life! They are ABSOLUTELY living, though.

The paramecium would eventually die because the paramecium wouldn't get any water and without the water-expelling vesicle the paramecium can't get the water out without getting other bacterias while doing so.

Vorticella is a type of ciliated protozoan that can be found in freshwater environments. They are characterized by a bell-shaped body with a long stalk that attaches to substrates. Vorticella feed on bacteria and other small organisms by creating water currents with their cilia.

Pseudoplasmodium is also known as a slug. A slug is about 2 to 4 mm long and composed of up to one hundred thousand cells.

By both asexual and sexual reproduction.

Asexual reproduction is accomplished by simple binary fission, where the cell just splits in two after replication of genes and organelle duplication.

Sexual reproduction requires two paramecium to align themselves side by side where micro nuclei are exchanged. ( paramecium have two nuclei )

Diatom shells, also known as frustules, have various uses due to their unique properties. They are commonly used in water filtration, as their porous structure can effectively remove impurities and toxins. Additionally, diatom shells are used in abrasive scrubbing products, such as toothpaste and metal polishes, due to their gentle but effective exfoliating properties. In agriculture, they can also be used as a natural insecticide by disrupting the exoskeletons of insects.

Paramecium reproduces asexually through binary fission, where the cell splits into two identical daughter cells. Plasmodium vivax reproduces both sexually and asexually, utilizing mosquitoes and humans in its life cycle. Euglena reproduces asexually through binary fission as well, but can also undergo a form of sexual reproduction called conjugation to exchange genetic material.

variable shape but probably as tall as wide. Since can see through optical microscope approx 0.001"?

Some examples of algae used in bioremediation include Chlorella, Spirulina, and Euglena. These species have the ability to absorb and metabolize pollutants such as heavy metals, nutrients, and organic compounds from contaminated water bodies, contributing to the cleanup of polluted environments.

The modern name of the cell amoeba is mycoplasma bacterium

Paramecium are unicellular, so they do not have multiple cells to compose an organ. However, most paramecium engulf the food by wrapping itself around it and bringing it inside the cell, using enzymes to break the food down and absorb the nutrients. The waste is excreted by pushing it out of the cell and into the environment.

Plasmodium cells move within the human body by infecting red blood cells and using them as a mode of transport to move through the bloodstream. Once inside a red blood cell, Plasmodium cells can change shape and move within the cell to evade immune responses.

Spyrogyra is a type of filamentous green algae. It is not a bacterium or a protozoan.

Waste exits the paramecium through a structure called the anal pore, located at the posterior end of the cell. This pore allows for the expulsion of unwanted materials and maintains the cell's internal environment.

Amoebas belong to the family Amoebidae within the phylum Amoebozoa. This family includes various species of amoebas that are characterized by their shape-shifting abilities and lack of a fixed form.

The amoeba is the slowest protist because it's only way of moving is the shift it's cytoplasm into the pseudopods, which take a long time.

This would be an example of transformation through evolution. Over time, genetic mutations and natural selection can lead to new species arising from common ancestors. In this case, the amoeba would have evolved from the bacteria through a series of genetic changes.

A paramecium discharges its trichocysts when it perceives a threat or disturbance in its environment. This response is meant to deter predators or capture prey by releasing harpoon-like structures from its cell membrane.

Conjugate is a generic term for two things joining together for a purpose.

In biology conjugation occurs when two bacteria or cells come together temporarily to exchange genetic material. The word is also used in chemistry to indicate two materials being combined so that the newly created combined material is easier to identify or isolate.

With animals and people, it also means joining together to exchange genetic material, which is another was to say sexual reproduction.
