what kind of circulatory system does Protista/Protoza have?
489251
protozoa are single cellular organisms thus they do not possess systems they have cell organells to perform different functions . in protozoa food is circulated with the help of vacuole

water vascular system helps the echinoderms in circulating the food & waste materials.....moreover it helps in their locomotion....

A circulatory system (cardiovascular system in biology classes) is an organ system that moves substances to and from cells; it can also help stabilize body temperature and pH (part of homeostasis). There are three types of circulatory systems (from simplest to most complex): no circulatory system, open circulatory system, and closed circulatory system.\n\nYou could get more information from the link below...

If you mean closed circulatory system (with veins and arteries then I guess that would be most of the Phylum Annelida. Also Cephalopod Molluscs and all vertebrates have closed circulatory systems.\n\nMany of the invertebrates(like antropods) have open circulatory systems

Protoplasm can only be as high as the water meniscus pressure. I suppose it could be very large diameter, but not very thick. The cell is feed through osmosis from the arteries. I suppose with more capillaries feeding it there is no limit metabolically. If amoebas could not reproduce, fission, then would they get very big?

The main component of protoplasm is....  Water!  That's pretty much it.  Inside the protoplasm, you've got all sorts of stuff swimming around -- organelles, chromosomes, proteans, aminos -- but the medium it's all floating in is really just H2O.

Through our circulatory system or blood.

a closed circulatory system, they are mammals like humans.

I believe, that you are looking for amoeba.\nAmoeba's are from the kingdom: Zooplankton,  which has animal like characteristics. The Amoeba, in particular, belongs to the phylum: sarcodina which have characteristics such as having a coinceboid shape (no shape), and being able to flow by extending it's cell membrane to form false feet (pseudopod).\n\nBut, there are still several others that can be classified in this category: Paramecium cordatum (from the phylum: ciliophora), Trypanosoma gambiensis (from the phylum: mastigophora), and Plasmodium vivox (from the phylum: sporozoa)\nAs you see, there is more then one choice in this matter.\n\nHope this helps!

cilia. these are little hairlike-protrusions that act as "legs" and push the paramecium along through the water.  Cilia are made up of microtubules.

The Cardiovascular System\n\n\n The cardiovascular system and the lymphatic system form what is collectively called the circulatory system. Together, these systems transport oxygen, nutrients, cell wastes, hormones, and many other substances to and from all cells in the body. The trillions of cells in the human body take up nutrients and excrete wastes every minute of every day. Although the pace of this exchange may increase with activity or slow with rest, it happens continuously. If it stops, so does life. Of the two systems, the cardiovascular system is the primary transport operator; the lymphatic system aids it in its function.\n\n\nDesign: Parts of the Cardiovascular System\n\nCardiovascular comes from the Greek word cardia, meaning "heart," and the Latin vasculum, meaning "small vessel." The basic components of the cardiovascular system are the heart, the blood vessels, and the blood. The system can be compared to a large muscular pump (the heart) that sends a fluid (blood) through a series of large and small tubes (blood vessels). As blood circulates through the increasingly intricate system of vessels, it picks up oxygen from the lungs, nutrients from the small intestine, and .....

u must be knowing that all organisms are classified into five kingdoms-monera,protista,anemalia,fungi and alge.\n\nthe MONERA phlum[group] consists of bacteria which are prokaryotic in nature -i.e, the cell doesnot have membrane bound organneles or nucleus.\n\nthe Protista group consists of organisms that are eukaryotic in nature-that is they have well defined organneles.\nthis is one reason that bacteria is kept in two separate groups.

Protists:  CLICK LINK BELOW FOR NAMES AND PICTURES ! YOU SHOULD BE ABLE TO PRINT THAT PAGE.\n\nSlime molds and algae are protists.\nSometimes they are called the odds and ends kingdom because its members are so different from one another.  Protists include all microscopic organisms that are not bacteria, not animals, not plants and not fungi.\nMost protists are unicellular. You may be wondering why those protists are not classified in the Archaebacteria or Eubacteria kingdoms.\nIt is because, unlike bacteria, protists are complex cells. \n \nThese delicate looking diatoms are classified in the protist kingdom. (Click link below for names and pictures.)

"Phylum Ciliophora:...A unique feature of all ciliates is the presence of two nuclei. The macronucleus  controls the cells growth and contains hundreds of copies of DNA. The micronucleus  is a small diploid nucleus used during the process of conjugation when genetic material between paramecia is swapped."\n\nThere are others out there, especially funguses that have multiple nuclei, but this seemed the most likely to be the one you were looking for.

Gastrovascular cavity, as the name indicates, functions in both digestion and the transport of nutrients to all parts of an animal body. Organisms belonging to two major phyla, the Cnidaria and the Platyhelminthes, possess gastrovascular cavities. The radially symmetrical cnidarians have a sac-like body in two distinct layers, with a jellylike layer between. Extracellular digestion takes place within the central cavity of the sac-like body. This cavity has only one opening to the outside and that is surrounded by tentacles in most cnidarians. The tentacles serve to capture prey.
