Bacteria

Protistans atomic number 18 eukaryotes. They throw a nucleus, queen-size ribosomes, mitochondria, endoplasmic reticulum, and golgi bodies. Many species induce chloroplasts. Some protists divide by trend of mitosis, meiosis, or both. The bulk of protistians atomic number 18 single-celled, plainly nearly every lineage besides has multicelled forms. Some be heterotrophs and some atomic number 18 autotrophs. Chytrids, water molds, ooze molds, protozans, and sporozans argon heterotrophs.  The 3 groups atomic number 18 arranged depending on whether they have animal-like characteristics, fungus-like characteristics, or plant-like characteristics.   Animal-like protists are called protozoans (first animals) because it is thought that they are the evolutionary history of animals. They conduct many common traits with animals. All of the animal-like protists are heterotrophs; they are un altered to make their own solid food. But distant animals, they are unicellular. Since th ey cant make their own food they must be open to move through their surroundings and cause their food.    - The animal-like protists are divided into four groups based upon their marrow of mobility and address for catching their food.

Amoeba, Paramecium    - Fungus-like protists are heterotrophic, they cannot make their own food, and thus they must be able to move at some point in their lives. These protists survey long hyphae-like strands thus they contain the physical appearance of fungi. The regeneration lies in that t! he hyphae of fungi are white while the hyphae of protists are usually bright in color.     The fungus-like protists can act as decomposers. They break down dead organisms by releasing digestive enzymes into the dead organism. In the end materials useful to other livelihood organisms are released into the surrounding environment.     Two examples of the fungus-like protists are water molds and lento lay molds. - Plant-like protists are...If you want to get a full essay, state it on our website: OrderCustomPaper.com
