the only statement about associative learning in unicellular organisms like the amoeba that I was able to find quickly is below, and that says no, you can't teach amoebas tricks. Their learning processes seem to be limited to habituation. Sorry.\n\nThe capacity for habituation of stimuli is important for the survival of organisms so that habituation appears to have been adopted at an early level of evolution. In this paper the question is raised and experimentally tested, whether or not unicellular organisms can habituate. A positive answer leads to the conclusion that a simple form of learning, such as habituation, is not necessarily associated with nervous systems, which do not exist in unicellular eukaryotes. At the same time, evidence for higher forms of learning, such as the association of two stimuli, has failed to be established experimentally in unicellular organisms.

"No protists are producers."\n\nI'm sure of it. Protists are the "junk drawer" of kingdoms.\nThe category of Protists includes many widely ranging microbes, including slime molds, protozoa and primitive algae. They are all eukaryotic <you-carry-ah-tick> creatures, meaning their DNA is enclosed in a nucleus inside the cell (unlike bacteria, which are prokaryotic <pro-carry-ah-tick> and have no nucleus to enclose their DNA. \n\nAlgae, Protozoa, Slime molds: Some produce and some consume.

RED TIDE:\nNot every plant poisoning is caused by a large, terrestrial plant. Several microscopic marine algae are notoriously poisonous to hapless humans who consume them in shellfish. \nThese Algae are tiny, single-celled plants that, like plants on land, capture and use the sun's energy to grow. The growth of algae is an essential life process, as it is the first step in transferring solar energy into aquatic food webs. The huge variety of marine algae are typically subject to annual cycles of growth & decay. These organisms thrive and multiply principally during the spring and summer, in response to increased light intensity and favourable levels of salinity & nutrients in ocean water. During the growth period, or bloom, each single algae cell may replicate itself one million times in two to three weeks.\n\nDuring the reproductive riot of the bloom, warm, shallow seawater tends to become discoloured by the sheer concentration of algae seeking the sunlight. This discolouration is a result of the various pigments the plants use to trap sunlight; depending on the species of algae present, the water may reflect pink, violet, orange, yellow, blue, green, brown, or red. Since red is the most common pigment, the phenomenon has come to be called Red Tide.\n\n\n2)DIVISIONS\nThe fungi kingdom is broken down into four phylums, the chytrids, zygote fungi, ascomycota, and basidium. The phylums are such:\n\nChytrids: Most scientifically inclined people assume that all the fungi were derived from an algal ancestor who lost its ability to photosynthesize. This then turned into to the flagellate fungi. A fungal ancestor then gave rise to the rest of the fungi, and usually this ancestor was assumed to be a member of the Chytridiomycota, a phylum which produced posteriorly, uniflagellated zoospores. The chytridomycota(chytrid) have the basic fungi key enzymes, cell walls made of chytin, and metabolic pathways that resemble the fungi's. They seem like the outcast of the fungi world, and are fungi because they are sort of like the rest of the fungi classes. \n\nZygote Fungi: Zygote fungi are terrestrial, which means they live only on land, usually on soil or decaying plants. One group of zygote fungi that live in the roots of plants is mycorrhizae. Another common zygote fungi is teh black bread mold, which absorb the bread's nutrients by spreading out on it, and extending hyphea in it. Zygote fungi have sporangia, which develop at the tips of hyphea. Haploid spores grow in the sporangium, and then are dispersed through the air. The reproduction will be talked about more extensivly in that section. Some zygote fungi can aim thier spores, and the picture on the left shows the spore being thrown by its sporangium at grass. \n\nAscomycota: Otherwise known as sac fungi, they can be aqueous, as well as terrestrial. The features that are importaint about this division is that they produce sexual spores in saclike asci. They reproduce asexually and disperse spores in the wind. They have a very long dikaryotic stage, in which they deveilop asci. \n\nBasidium: These are also known as club fungi, which have club-like tops. Typical mushrooms are an example of the club-like reproductive site. They decompose wood, and other plant material. The basidium have fruiting bodys called basidiocarps, which are the source of sexual spores. They sometimes attract flies

Amoeba are among the largest single celled organisms, far larger than any bacteria.  Some amoeba are large enough to be seen without needing a microscope!\n\nBacteria are the smallest living things and mycoplasms are the smallest living bacteria (known as nanobacteria).\n\nIf by creatures you mean animals, then the smallest depends a bit on your definition of "small".  The shortest is probably little Trichoplax adhaerens, which looks a bit like a hairy, multi-cellular amoeba.\n\nThe smallest animal in terms of number of cells is probably some kind of Mesozoa, a set of worms famous for being very short and only a few cells across, so much thinner than Tricoplax and less massive.\n\nThe smallest vertebrate is a species of fish that was just discovered recently, though I forget the name of it, sorry.  :-)\n\nIt's recently been discovered that a few single-celled organisms are, in fact, evolved from animals.  If you would count these as animals, they would be the smallest animals, though that would be merely a technicality.\n\nAll of this applies only to adult forms, of course.  We're all very very small to begin with!

I don't think so becasue prokaryotes means ''primitive cell'' so eukaryotes come form themm they are ''true cells''. \n\n2. electorn microscoep,- advantges: 3d images, very high resolution.\ndisadvanteges: long time to prepare sample, sample most be dead, electron micrsocope are expensive, and the images are in black and white.\n\n I you want to know how a susbtance enters a cells is better with a light microscope because you cant have a life cell. but i think you could still study it with electron. But take in consideration that disavantages i told you.

The amoeba is a tiny, one-celled organism. There are many different types of amoebas.\n Anatomy: An amoeba consists of a single blobby cell surrounded by a porous cell membrane. The amoeba "breathes" using this membrane - oxygen gas from the water passes in to the amoeba through the cell membrane and carbon dioxide gas leaves through it. A complex, jelly-like series of folded membranes called cytoplasm fills most of the cell. A large, disk-shaped nucleus within the amoeba controls the growth and reproduction of the amoeba. \n\nDiet: Amoebas eat algae, bacteria, plant cells, and microscopic protozoa and metazoa - some amoebas are parasites. They eat by surrounding tiny particles of food with pseudopods, forming a bubble-like food vacuole. The food vacuole digests the food. Wastes and excess water are transported outside the cell by contractile vacuoles.\n\nLocomotion: Amoebas move by changing the shape of their body, forming pseudopods (temporary foot-like structures). The word pseudopod means "false foot."\n\nReproduction: Amoebas reproduce asexually by binary fission. A parent cell divides (the nucleus also divides in a process called fission) and produces two smaller copies of itself.

In the trade its referred to as an HAB--Harmful Alge Bloom. Occasionally, the algae grow very fast or "bloom" and accumulate into dense, visible patches near the surface of the water. "Red Tide" is a common name for such a phenomenon where certain phytoplankton species contain reddish pigments and "bloom" such that the water appears to be colored red. The term "red tide" is thus a misnomer because they are not associated with tides; they are usually not harmful; and those species that are harmful may never reach the densities required to discolor the water.\n\nUnfortunately, a small number of species produce potent neurotoxins that can be transfered through the food web where they affect and even kill the higher forms of life such as zooplankton, shellfish, fish, birds, marine mammals, and even humans that feed either directly or indirectly on them. \n\nhttp://www.whoi.edu/science/B/redtide/whathabs/whathabs.html\n\nhttp://en.wikipedia.org/wiki/Red_tide\n\nhttp://seagrant.gso.uri.edu/factsheets/redtide.html\n\nhttp://www.whoi.edu/redtide/
