Protists

dual flagella, meaning it possess two flagella

Animal-like protists are called protozoa. Protozoaare single-celled eukaryotes that share some traits with animals. Like animals, they can move, and they are heterotrophs.

Amoeba are protists and they are eukaryotes, therefore they do have nuclei...

There is a one difference. Population's growth of P.aurelia is much faster than P.caudatum, so the first species squeezes out another population. But why? Because the first population has better ability to gain food and solar light to accelerate its growth.

Amoebas are single-celled organisms that belong to the Protista kingdom. They do not have specialized organ systems like higher-level organisms. Instead, their functions are carried out by different organelles within the cell.

Paramecium feed by using their cilia to sweep food particles such as bacteria and algae into their oral groove. Once the food is inside the oral groove, it is engulfed by the cell membrane forming a food vacuole. The food vacuole then fuses with lysosomes for digestion.

Centric diatoms have a spherical shape that helps them float and stay suspended in the water column, which is more common in saltwater environments with consistent water movement. Pennate diatoms have a more elongated shape that allows them to attach to surfaces in freshwater environments where there may be less water movement. This difference in shape relates to their respective preferences for saltwater and freshwater habitats.

Paramecium feed on microorganisms like bacteria, algae, and yeasts. In order to gather its food the paramecium uses its cilia to sweep the food along with some water into the cell mouth after it falls into the oral groove. The food goes through the cell mouth into the gullet, which is like the stomach. When there is enough food in it so that it has reached a certain size it breaks away and forms a food vacuole. The food vacuole travels through the cell, through the back end first. As it moves along enzymes from the cytoplasm enter the vacuole and digest it. The digested food then goes into the cytoplasm and the vacuole gets smaller and smaller. When the vacuole reaches the anal pore the remaining undigested waste is removed.

Amoeba is a microphagous feeder, which means that it feeds upon small aquatic organisms like bacteria, flagellates, ciliates and minute food particles.

When a hungry Amoeba approaches to some food particle, it produces out its pseudopodia in the form of food cup which engulf the food particle by turning into food vacuole. the food also contain some water. this complete ingestion. the next step is digestion which is faciliated by the lysosomes. A few lysosomes surround the food vacuole and get fused with the membrane to discharge their enzymatic contents(proteases, amylases and lipases)into it. Hence the digestion is intacellular. At this stage the vacuole becomes a digestive vacuole. It decrease in size as the water is withdrawn and its content first become acidic(pH 5.6) and then alkaline(pH 7.3). When the digestion is completed, the digestive vacuole membrane is drawn into numerous fine canals. the soluble food particles are passed into the canals and finally into the surrounding cytoplasm by micropinocytosis. the digested food, water and minerals are absorbed(absorption) into the cytoplasm and circulate in it, through cyclosis where the food is assimilated into new protoplasm or is oxidized to librate energy. the undigested food is egested by exocytosis at the rear end.

Examples of one-celled animal-like protists include amoebas, paramecia, and trypanosomes. These protists are eukaryotic organisms that possess animal-like characteristics such as mobility and heterotrophic feeding behavior. They can be found in various aquatic environments and play important roles in nutrient cycling and food chains.

Amoebas reproduce by binary fission, a process where a single cell divides into two identical daughter cells. This is a form of asexual reproduction commonly observed in unicellular organisms like amoebas.

The Latin name for paramecium is Paramecium caudatum.

Most jellys are axially symmetrical. Let's do a quick "thingie" to see what that is. Picture a dinner plate on a table. Stand a candlestick on it in the middle. That candlestick is the axis here, and the plate is symmetrical around or about the candlestick. Most jellys are symmetrical in that way.

you should refer to a sliding microtubule model. in this model, there is a "9+2" structure or pattern, along with spokes, motor proteins and a basal body. the spokes connect to the 2 microtubules in the center and the motor protein, dynein, connects the 9 pairs to each other. dynein "walks" one microtubule pair relative to the other. if they weren't fixed in place at either end, they would move past each other. they are fixed at one end by attachment to the basal body, which is attacked just inside the plasma membrane. therefore the walking motion pulls the microtubule pairs over (while spokes contribute to the lack of free movement). keep in mind that dynein requires energy. it binds, releases and moves, binds, releases and moves. (think of a cat climbing a tree.)

In 1703, an anonymous English microscopist sketched and described the first known diatom, Tabilarria Flocculosa. His sketches were published by the Royal Society of London. His name is yet to be known until this day.

Pseudopodia are temporary protrusions of the cell membrane in amoeboid cells like amoeba. These structures are used for movement and to engulf food particles through phagocytosis. Pseudopodia are formed by the cytoskeleton and are constantly changing shape as the cell moves.

Yes, many protists are motile. They may move using structures like flagella, cilia, or pseudopods. Motility is an important characteristic that allows protists to find food, escape predators, and navigate their environment.

Amoebas like Entamoeba histolytica can cause damage to the liver by invading and creating abscesses, a condition known as amoebic liver abscess. However, amoebas typically do not damage brain tissues as they primarily affect the intestines. In rare cases, neurological symptoms can occur if the infection spreads.

Paramecium look like little peanuts or slippers, with one end coming to a point. They are very tiny, (about 0.02 in) and you will need to look under a microscope to see one, and it is very difficult as they move quickly.

Parameciums reproduce asexually by binary fission, where the cell divides into two equal parts. They can also undergo sexual reproduction through a process called conjugation, where genetic material is exchanged between two organisms.

A paramecium typically has thousands of cells, which make up its single-celled organism structure. The cells in a paramecium are specialized to perform various functions, such as movement, feeding, and reproduction.

phytoplankton found in the ocean. They play a crucial role in marine ecosystems by contributing to the base of the food web and producing a significant amount of oxygen through photosynthesis. Additionally, diatoms have unique cell walls made of silica, which give them their distinct shape and help with nutrient cycling in the ocean.

Well, honey, Mercury might be a planet, but it ain't no diatomic element. Diatomic elements are those that naturally exist as molecules composed of two atoms bonded together, like hydrogen or oxygen. So, Mercury can keep spinning around the sun, but it ain't gonna be part of the diatomic club anytime soon.

They are both cells and are both living.

A dolphin grows rapidly in the first few years of its life, reaching sexual maturity between the age of 5 and 13. They continue to grow in size and strength, adapting to their environment to become efficient hunters and social members of their pod. As they age, they may experience changes in their physical abilities and behavior, but can live up to 50 years or more.
