What Are The Four Major Phyla Of Animal Like Protists?
what are the three major phyla of plant-like protists? the four phyla of fungus like protists?
im doing some bio hw and im stumped! i looked everywhere
Animal-like Protists (Protozoa) - 4 phyla
Fungus-like Protists - 2 phyla
Myxomycota (Slime molds)
Oomycota (Water Molds & Mildews)
What characteristic is used to seperate the animal-like protista into phyla?
Use complete sentences.
There are four separate phyla of protists with animal characteristics. In early classification schemes, they were clumped together and called protozoa to separate them from the more plantlike protists:
Based on method of locomotion -
•Sarcodina - pseudopodia
•Ciliata - cilia
•Zoomastigina - Flagellata

What are the distinguishing characteristics of each group?
(kingdoms and the major phyla and divisions of animals and plants) _____________________ Organisms and Populations -- Diversity of Organisms Topic: Phylogenetic Classification
Depending who you ask, number of kingdoms vary. A modern biologist will probably say there are three kingdoms - eukaryotes, archaea, bacteria. Archaea and bacteria are microorganisms without nuclei. Eukaryotes have a true nucleus. Older classification systems will divide eukaryotes into the kingdons "plant", "animal", "fungus", and "protist". Protists are little microorganisms like algae or the little things you see swimming around in pond water if you look at it under the microscope. Plants have large vacuoles, cell walls, chloroplasts, and the ability to photosynthesize and thus make their own food. Animals lack chloroplasts and cell walls, so they can't make their own food and have to eat other things. Fungi (such as yeast, mold, or mushrooms) have cell walls but don't photosynthesize - they live off other things, such as food that has been left in your refrigerator for way too long.
In the animal kingdom, one of the major phyla is chordata, which means everything with a backbone. That gets further divided into mammal, bird, reptile, amphibian, fish. Things without backbones get divided into a lot of other phyla, but it's way too much to go into here. You can see a lot of other phyla at Wikipedia.
Movement (or not) of Protists.?
My science question says to label the movement (or not?) of my kingdom, protists, and I've been looking everywhere and can't find it. Do all Protists move? Some? If so, how? I've been checking everywhere, and I just need help, thanks.
Protists can be grouped into three subcategories: animal-like protists, fungus-like protists, and plant-like protists. EVERY CATEGORY OF PROTIST HAS MOVEMENT.
Protists with Pseudopods
These protists move by extending their bodies forward and then pulling the rest of their bodies forward as well. The finger-like structures that they project forward are called pseudopods. The pseudopods are also used to trap food.
>>The ameba is an example of this type of animal-like protist.
Protists with Cilia
These protists move by beating tiny hair-like structures called cilia. The cilia act as tiny oars that allows the protist to move through its watery environment.
>>The paramecium is an example of this type of animal-like protist.
Protists with Flagella
These protists move by beating their long whiplike structures called flagella. These protists can have one or more flagella that help them move. Many of these protists live in the bodies of other organisms. Sometimes, they help their host, while at other times they harm their host.
>>The Giardia is an example of this type of animal-like protist.
These protists are chartacterized mainly by the way they live. All of these protists are parasites. Many of these protists cause diseases such as malaria.
>>The Plasmodium is an example of this type of animal-like protist.
Fungus-like protists are heterotrophs with cell walls. They also reproduce by forming spores. All fungus-like protists are able to move at some point in their lives. There are essentially three types of fungus-like protists: water molds, downy mildews, and slime molds.
Plant-like protists are autotrophic. They can live in soil, on the bark of trees, in fresh water, and in salt water. These protists are very important to the Earth because they produce a lot of oxygen, and most living things need oxygen to survive. Furthermore, these plant-like protists form the base of aquatic food chains.
>>The plant-like protists are divided into four basic groups: euglenoids, dinoflagellates, diatoms, and algae. Some of the first two have movement.
How are Protists important to humans?
Hello. I'm having a research in my school and my teacher wants to know How are Protists important to humans or helpful to humans. Please answer this question. Need FULL information. :) Thanks a lot.
Some protists cause disease in humans. Malaria is caused by plasmodium (protists); African Sleeping Sickness is caused by Trypanosoma (protists); Giardiasis is caused by Giardia (protists); amoebic dysentery is caused by amoeba (protists).
The protophyta, or algae, are the protists which play the most beneficial role for humans. Many of the protophyta form the basis of the food chain which drives the engine of life on the planet. The algae create food for other organisms, growing and expanding by absorbing the light of the sun through photosynthesis and serving as food for the lowest-level animal organisms, which in turn serve as food all the way up the food chain. The vast majority of the plankton in the ocean consists of various protists.
