Protista5A1

= This page was created by Brian, Shreyas and Akira = =__// PROTISTA KINGDOM //__= =Different from other kingdoms.= ====(Fungi)Protists are generally unicellular. Fungi are multicellular. Fungi are mainly saprotrophic, while protists are not (they can be heterotrophic, autotrophic, parisitic and saprotrophic). They have different cell wall compositions (Fungi cell wall is made of chitin, protist ones aren't). We are pretty sure protists reproduce mainly asexually and fungi reproduce sexually by producing spores. Also fungi perform extracellular digestion, protists again do not.====

We used this nice information from:[]

(Animal)You could say protists are heterotrophs or autotrophs, and animals are only heterotrophs. However, animals such as sea anemones and coral can be both.

These are the three examples:

1. Multicellular animals, protists, single celled. However, there are some protists that are multicellular, like brown algae.

2. Method of movement: protists - cilia, pseudopods, flagella. animals, muscles and bones.

3. Reproduction: animals mainly sexual with egg and sperm, protists binary fission.

(Monera)Kingdom Monera are strictly single-celled organisms, mostly bacteria. Kingdom protista is kind of wierd, because there is no strict defenition of what it is, but rather it is everything not included in all the other kingdoms. An example would be algea - it does not fit into any other kingdom, so it would be considered protista. (Other information) The main difference is that the kingdom Monera lacks a nuclear membrane and also lacks menmbrane bound organelles. Whereas protists have a nuclear membrane and membrane bound organelles. Also moneras are strickly unicellular whereas some protists can be multicellular though majority are unicellular.

This is our link that we used to write about monera and protist:[]

(Plant)In a plant, cells are very organized in their placement, some, like the elodea plant, resemble bricks. These cells have a very stiff outer covering called a cell wall and most have chloroplasts which appear as very conspicuous green dots. These cells also contain a large central vacuole that when filled with water is integral to plant support. Protists are in a class of their own. These are one-celled creatures that can function on their own, a unique feature of there three kinds of cells. They often have strange shapes that can move and adjust, such as the amoeba, because they have an outer membrane instead of a cell wall. Often, protists have cilia or flagella to aide with cell movement and intake of food. Protists can have properties of both plants and animals at the same time, as is the case in the euglena.

= [] = = Where Protist live and how protits move and what is their cell made of = ==== Protists live in almost any environment that contains liquid water or colonies. Many protists, such as the algae, are photosynthetic and are vital primary producers in ecosystems, particularly in the ocean as part of the plankton. Other protists, such as the Kinetoplastids and Apicomplexa, are responsible for a range of serious human diseases, such as malaria and sleeping sickness. ====

====Protist cells are made of the same stuff that most other eukarotic cells are made of. They have a phospholipid bilayer for a plasma membrane, and contain mostly cytosol, which is mostly water. Some have cells walls (diatoms, for instance, create cell walls made of glass), and some are capable of carrying out photosynthesis with chloroplasts. Protists move in several ways, but the two most common are cilia (tiny hairs that move the cells one way or another...like a Paramecium ) or by moving around like a blob of Jell-O (a pseudopod, like the common amoeba).==== []

= About Protista = ==== They have only one cell and that cmedia type="custom" key="8922702" width="235" height="208" align="right"ell is a nucleus and they are photosynthetic organisms, such as diatoms and dinoflagellates, are classified as protists or algae. Recently the term has also been used for members of the kingdom Protista, which features in certain five-kingdom classifications of the living world. ==== ====And They live in colonies. Most of the protists reproduce by mitosis, and some by meiosis and reproduction. A major group of protists include plankton. Other examples include amoeba, diatom, euglena, paramecium and algea. Some hetrotrophic protista include chytrids, water molds, slime molds, protozans, and sporozans. "Giardia lamblia" is an animal like protist. Hope this answer was helpful. Protists are so small that they do not need any special organs to exchange gases or excrete wastes. Their small size is also due to the inability of cilia or flagella to provide enough energy to move a large cell through the water.Protists eat by phagocytisus - they engulf their food in their cell membrane and pinch off a section of membrane to form a hollow space inside the cell. This gollow space, now enclosed by membranes, is called a vacuole. Vacuoles are handy little structures. Protists also use them to store water, enzymes, and waste products. Paramecium and many other protists have a complex type called a con tractile vacuole, which drains the cell of waste products and squirts them outside the cell.====
