Protists

Yes, but not in the organs that large forms of life have, such as stomach, intestines livers, etc. Instead, they have what are called vacuoles. These vacuoles are small, circular pockets inside the amoeba spontaneously creates that can either digest food or excrete waste. When an amoeba eats, it engulfs its food with its pseudopods, or blob shaped projections. The food it engulfed creates a little pocket, or vacuole, that is then used to digest with and later, the vacuole is released from the amoeba containing the waste it created from digestion.

Yes, centric diatom are algae that are species that display radial symmetry. Diatoms are like clams, they have a two-part silica cell wall, called frustules. Diatoms are then divided into two groups based on the symmetry of their frustules, bilaterally symmetrical are called pennate diatom and centric diarom are radial symmetrical.

The hair-like extensions on a paramecium are called cilia. These cilia beat in a coordinated fashion to help the paramecium move through its aquatic environment.

When things the amoeba wants to eat - other cells, little food particles, etc. - stick to surface molecules (the term for surface molecules that recognize and bind to specific factors - proteins, sugars, hormones - is receptors), the shape changing machinery is set in motion, and the membrane flows around the particle of lunch. When it's surrounded, the membrane comes in contact with itself on the other side of the particle and merges, actually capturing the particle within the amoeba in a little membrane-covered bubble, called a vacuole. This process is called "phagocytes", which basically means cell eating.

The name for protists that live in water is plankton. They are microscopic organisms that form the base of the aquatic food chain.

An amoeba moves using pseudopods, which are temporary bulges of the cell membrane and cytoplasm that help in locomotion and capturing food. These pseudopods can extend and retract to propel the amoeba in its environment.

Plants, certain protists, and monerans are collectively called autotrophs, as they are able to produce their own food through photosynthesis or other processes without needing to consume other organisms for nutrition.

Parameciums move by using hair-like structures called cilia that cover their outer surface. These cilia beat in a coordinated manner, propelling the paramecium through water in a spiraling fashion. This movement helps them to find food and avoid predators.

Paramecium need to regulate their internal water content to prevent bursting due to excessive water intake through osmosis. They remove water by contracting their contractile vacuole, which expels excess water from the cell to maintain internal balance, ensuring their survival in various environments.

Amoebas are protists and therefore unicellular eukaryotic organisms. This means that they contain a nucleus. The DNA of ANY eukaryotic organism is found in the nucleus.

Amoebas reproduce asexually through a process called binary fission. In this process, the parent cell divides into two identical daughter cells. The nucleus of the parent cell first undergoes division, followed by cell membrane separation, resulting in the formation of two new individual amoebas.

This is an example of endocytosis, a process where the cell takes in materials from its external environment by engulfing them in a vesicle formed from the cell membrane. It is a common mechanism used by cells to take in nutrients and other substances.

Phylum Amoebozoa.

Some unicellular organisms with ameboid forms are also commonly called "amoeba", but they do not belong always to phylum Amoebozoa. Amoeba is a genus, however, all species of phylum Amoebozoa are currently called amoebae.

Complexity of paramecium over amoeba.

Amoeba has no definite shape, moves by pseudopodia and must capture its food with cytoplasmic projections. They reproduce by binary fission alone.

Whereas Paramecia contain a pellicle that gives it a more defined shape. It possesses cilia for movement, nuclei and awell defined mouth pore for food to enter. It also contains 2 stationary contractile vacuoles that helps maintain homeostasis. It is capable of reproduction in two different ways: conjugation and binary fission.

Paramecium are typically found in freshwater environments such as ponds, lakes, and slow-moving streams. They are also commonly found in microbiology laboratories where they are studied as model organisms.

Amoebas do not have eyes or light-detecting organs, so they do not have the capability to perceive or respond to light like organisms with photoreceptors do.

Amoebas are unicellular organisms. The way that life is set up it is far more efficient to have cells be small because of the inefficiencies of a cell being so large. Small is conducive to a large surface to volume ratio, the larger surface you have the more you can exchange (fluids, nutrients,etc.). All life needs water, amoebas would not be able to retain this much water to become two tons in the first place and the energy the cell membrane would have to expend preventing this water from escaping would be tremendous (probably more than an average human's metabolism) and we have BILLIONS of cells, with an amoeba we are talking about only ONE cell.

Plasmodium vivax is a species of parasite that causes malaria in humans. It belongs to the kingdom Protista, which includes single-celled organisms that do not fit into the other traditional kingdoms of plants, animals, or fungi.

Amoebas are single-celled organisms that use pseudopods for movement and feeding. They capture food particles by surrounding them with their pseudopods and forming a food vacuole for digestion. Amoebas play a vital role in their ecosystem by breaking down organic matter and recycling nutrients.

The word "amoeba" is Latin in origin, derived from the Greek word "amoibe," meaning "change" or "variation." It refers to a single-celled organism that can change its shape.

Ever since the atom joined with another atom to create a diatom, it has been the greatest structure in the universe. However, when the polymer was created, which has not just two atoms, but many thousands of atoms, the diatom has been bitter with jealousy that it is no longer the biggest fish in the pond. Therefore the polymer is the diatoms enemy.

I can guess which sheet you are looking for and it is in the link below...Don't

worry it is safe as I used it myself. The answer to this would be: 'There would be a greater concentration of dissolved molecules inside a cell.' Explanation: 'Water will move into Paramecium by osmosis because the concentration of water molecules is higher outside the Paramecium than inside.'

Once you click on the link you want to press 'show in folder' and then 'open with' microsoft word or adobe reader or whatever you use. Just don't click open with your browser that you are using as that will just download more copies... Hope this helped!!! :)

Yes, protists can move independently through the use of structures like flagella, cilia, or pseudopods. These structures allow protists to swim, glide, or crawl in their aquatic or moist environments.

Yes, phytoplankton are a type of microorganisms that include many types of algae. They are microscopic, photosynthetic organisms that drift in water bodies and form the base of the aquatic food chain.
