Summarize how multicellularity advanced the evolution protists?

The first were likely sponges. It allowed them to use specialized cells to move water to bring potential nutrients to other cells specialized in consuming them. It allowed other cells to create an external structure that enabled the first multicellular organism to form. By creating this group of different cells that worked together, it made it much more difficult for the prey to evade them. It allowed the formation of much more complex organisms. The ability to force water through a sort of filter may seem primitive compared to later adaptations but this was a weapon of mass destruction in its day.

What are two common characteristics of fungus like protists?
Its really three and they are Cell wall composition, Multicellularity and Photosynthetic pigments
Why is it misguided to try to find your earliest eukaryote ancestor among modern day protists?
It is misguided to try to find our eukaryotic ancestor among modern-day protists because the Protists living today have been through a process of evolution just as extensive as the one that produced every other living organism.
What two characteristics do all eukaryotes share?
Eukaryotes contain a Nuclei and membrane bound organelles as well as a nucleus in which the DNA of the cell is contained.
Are protists mostly multicellular?
No, protists are generally unicellular.
Does protists have a nucleus?
Protists are eukariyotic creatures.So they have nucleii.
Why are protists considered advanced?
There are many ways in which protists are more advanced than bacteria. Protists possess a nucleus. Protists can also be unicellular or multicellular while bacteria is only unicellular.
What is a protists cell?
Eukaryotic. This means that it has advanced cell structure, including a nucleus. Protists were the first Eukaryotes.

What is a protists cell type?
Eukaryotic. This means that it has advanced cell structure, including a nucleus. Protists were the first Eukaryotes.
During the evolution of protists it is hypothesized that what occurred?
B and C only for plato users
Describe margulis' theory about the evolution of protists?
Margulis hypothesized that the first Eukaryota evolved from a symbiosis of several cells.

How do protists get nutrients to their cells?
Animal-Like Protists * Once referred to as protozoa, the animal-like protists are alike in that they do not get their nutrients by performing photosynthesis, but instead get them from consuming either other organisms or bits of organic matter. They digest this material internally and have evolved various means of moving toward their prey. The so-called ciliate protists move through use of hair-like cilia surrounding their bodies; amoeboid protists move by means of extending pseudopodia or "false feet." Many amoeboid protists are parasites, and some of them are human parasites that live in the digestive system. Plant-Like Protists * Protists that get their nutrition by performing photosynthesis are known as algae. Some algal species provide examples of colonial multicellularity, defined as a form of life in which individual cells form stable associations with one another but do not take on specialized roles. Other algal protists provide examples of true multicellularity: a form of life in which individual cells exist in stable groups, with different cells specializing in different functions. Fungus-Like Protists * Some protists get their nutrients by extending slender filaments to a food source, after which they digest that food source externally, in the way fungi do. Protists in this category include the oomycetes, one group of which is known as the water molds. Many oomycetes are saprobes, meaning organisms that obtain their nutrition from dead organic matter. These organisms are thus "decomposers" that help recycle organic matter.
Which group of organisms includes only multicellular heterotrophs?
Protists
Do a live plant or animal may be made of only one cell?
Part of the definition of both the plant and animal kingdom is multicellularity. Technically, no plant or animal under the current definition can be unicellular. However, the protist kingdom contains one-celled organisms with plant or animal characteristics. In fact, animal-like protists and plant-like protists used to be referred to as animals or plants. Many types of green algae are single-celled, as are amoeba and paramecia.
Which is the group includes organisms all of which are absorptive in their nutrition?
protists
