Protists

The amoeba moves its psuedopodia (false feet) around the food particle. thus a food vacuole is formed.then the amoeba secretes digestive enzymes into the food vacuole and the food particle is digested and assimilated.the waste particle is thrown out by moving the particle towards the surface of the body and it is excreted. :)

they are classified in the phylum Sarcodina

The parameceum can reproduce asexually and sexuallly while the other 2 can only do it asexually. they have diifferent structures (Google the images) and the euglena has a flagellum while the paramecium has cilia and they eat differently. the amoeba works its pseodopotium around its food and digests it in the food vacuale the paremecium uses the cilia to get a water current going and the food gets sucked in and the euglena uses photosynethesis by using its stigma to indicate areas of light and if not then it will just get food like the other 2

Amoebas reproduce asexually through a process called binary fission, where the cell splits into two identical daughter cells. Under certain conditions, they may also undergo sexual reproduction by forming haploid gametes that fuse to create a diploid cell, which eventually undergoes meiosis to form new haploid amoebas.

As it moves along, enzymes from the cytoplasm enter the vacuole to digest the contents, digested nutrients then going into the cytoplasm, and the vacuole shrinks. When the vacuole reaches the anal pore, it ruptures, expelling its waste contents to the exterior

Viruses are the smallest microbes known that cause disease. They are sub-microscopic. This means that they can not be seen with a regular microscope because they are too small (measured in nanometers). It takes an electron microscope to see a virus particle.

The second microbe that is among the smallest would be bacteria and then probably protists, as a generalization, after that (protists and bacteria have wider ranges of sizes than viruses). Bacteria are microscopic living organisms, while the viruses are non-living sub-microscopic organisms. Protists are single-celled living organisms, such as protozoa.

It is in the protista kingdom.

Some protists can be decomposers, breaking down organic matter and recycling nutrients in ecosystems. However, not all protists are decomposers; many protists have other ecological roles such as producers or consumers.

Amoebas are preyed upon by various organisms such as other protists, small invertebrates, and even some fungi. Predators use various methods including engulfing, engulfing and dissolving, or puncturing the cell membrane to consume amoebas.

Parameciums are very unique. They are little organisms that do not have brains, eyes, ears or a heart but can sense gravity, light and temperature. THEY EAT BY EATING THROUGH A HOLE IN ONE SIDE OF THEIR BODY, DIGEST IT, AND EXCRETE IT THROUGH THE OTHER SIDE. The side that they excrete it through, is called the anal pore.

No, cnidarians are not protists. Cnidarians are a diverse group of animals that include jellyfish, corals, and sea anemones. Protists are a separate group of eukaryotic organisms that are not classified as animals.

Yes they do. Protist means Protista in Latin. Some Protists have one cell and some have more than one. Some Protists can make their own food and some cannot. They also are eukaryotic in nature.

The process an amoeba uses when it engulfs a food particle is called phagocytosis. During phagocytosis, the amoeba extends its pseudopods around the food particle, forming a food vacuole. Then, enzymes are secreted into the vacuole to digest the food. The digested nutrients are absorbed by the cell.

A paramecium moves by using its cilia, which are hair-like structures that cover its outer surface. The coordinated beating of these cilia propels the paramecium through the water in a spiral, tumbling motion.

Diatoms are a type of phytoplankton with a distinctive cell structure made of silica, giving them a glass-like appearance. They come in various shapes, from circular to elongated, and can form intricate patterns and designs. Under a microscope, diatoms appear as colorful, geometric shapes with intricate detailing.

Animal-Like Protists

* Once referred to as protozoa, the animal-like protists are alike in that they do not get their nutrients by performing photosynthesis, but instead get them from consuming either other organisms or bits of organic matter. They digest this material internally and have evolved various means of moving toward their prey. The so-called ciliate protists move through use of hair-like cilia surrounding their bodies; amoeboid protists move by means of extending pseudopodia or "false feet." Many amoeboid protists are parasites, and some of them are human parasites that live in the digestive system.

Plant-Like Protists

* Protists that get their nutrition by performing photosynthesis are known as algae. Some algal species provide examples of colonial multicellularity, defined as a form of life in which individual cells form stable associations with one another but do not take on specialized roles. Other algal protists provide examples of true multicellularity: a form of life in which individual cells exist in stable groups, with different cells specializing in different functions.

Fungus-Like Protists

* Some protists get their nutrients by extending slender filaments to a food source, after which they digest that food source externally, in the way fungi do. Protists in this category include the oomycetes, one group of which is known as the water molds. Many oomycetes are saprobes, meaning organisms that obtain their nutrition from dead organic matter. These organisms are thus "decomposers" that help recycle organic matter.

They do not have a cell wall. They have a cell membrane, which is the outer layer of the cell. Much like skin in a human. The only type of cells that have a cell wall are plant cells. :)

Diatoms grow by taking in nutrients from their environment, such as carbon dioxide, silicate, and nitrates, to build their silica-based cell walls. Through a process called cell division, diatoms replicate their cells by splitting in half, producing two identical daughter cells. This rapid reproduction allows diatoms to form dense populations in aquatic environments.

A paramecium grows by increasing the size of its cell through a process called binary fission, where it replicates its DNA and divides into two identical daughter cells. It also grows by consuming food and absorbing nutrients from its environment through its oral groove.

Parmamecium has a definite shape and slides through water while Amoeba is a single celled organism that has no definite shape and consisting of a mass of protoplasm containing one or more nuclei surrounded by a flexible out membrane.

Diatoms are the major primary producer in the globe. They produce oxygen more than the all the world tropical forests put together. Whatever the oxygen taken inside by us are atleast 1/4 of its from diatoms. Recently freshwater diatoms are also used as bioindicators, to detect the pollution.

Amoeba proteus, the common amoeba, is currently classified in Kingdom Amoebozoa. Older sources may list amoebae under the now-defunct Kingdom Protista or (in really old books) Kingdom Animalia. The change is because of the current trend to define taxonomic groups on evolutionary kinship.

An amoeba gets nutrients through the process of endocytosis, which is absorbing another organism into itself. This is done with a pseudopod, which is a temporary appendage used for absorbing another organism.
