Bacteria

Protistans atomic number 18 eukaryotes. They throw a nucleus, freehanded ribosomes, mitochondria, endoplasmic reticulum, and golgi bodies. Many species induce chloroplasts. Some protists divide by focussing of mitosis, meiosis, or both. The bulk of protistians atomic number 18 single-celled, simply nearly every lineage besides has multicelled forms. Some be heterotrophs and some be autotrophs. Chytrids, water molds, ooze molds, protozans, and sporozans atomic number 18 heterotrophs.  The trine groups atomic number 18 arranged depending on whether they have animal-like characteristics, fungus-like characteristics, or plant-like characteristics.   Animal-like protists atomic number 18 called protozoans (first animals) because it is thought that they are the evolutionary history of animals. They shell out many common traits with animals. All of the animal-like protists are heterotrophs; they are un vary to make their own solid food. But distant animals, they are uni cellular. Since they cant make their own food they must(prenominal) be adequate to(p) to move through their surroundings and misgiving their food.    - The animal-like protists are divided into four groups based upon their marrow of mobility and adroitness for catching their food. They are divided into: protists with pseudopods, protists with cilia, protists with flagella, and parasitic protists.

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 field of study long hypha e-like strands thus they contain the physica! l appearance of fungi. The miscellanea lies in that the 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 provender organisms are released into the surrounding environment.     Two examples of the fungus-like protists are water molds and flabby lay molds. - Plant-like protists are...If you want to get a full essay, hallow it on our website: OrderCustomPaper.com
