Protists are majorly unicellular but there are some exceptions of multicellular protists that mostly belong to algae.

. Mammals gave rise to birds. Up to 10 cash back A protist is broadly recognized as a eukaryote that is not an animal fungus or plant Protists are diverse in part due to endosymbiosis a process by which small unicellular organisms are engulfed by larger unicellular organisms and eventually evolve to become organelles All protists are unicellular by definition Correct answer. Since many protists live as commensals or parasites in other organisms and these relationships are often species-specific there is a huge potential for protist diversity that matches the diversity of hosts.

A few protists live as colonies that behave in some ways as a group of free-living cells and in other ways as a multicellular organism. They arose from mammal-like reptiles in the Jurassic but. Foraminiferans and the cercozoans.

C Euglena uses a whip-like tail called a flagellum to propel itself. They are a diverse group of. Since many protists live as commensals or parasites in other organisms and these relationships are often species-specific there is a huge potential for protist diversity that.

Protists are best described as. Start studying 305 Quiz. Which of these groups includes unicellular organisms that due to the structure of their cell walls can withstand pressures equal to the pressure under each leg of a table supporting an elephant.

It involves gametes or cells produced for the. Some protists are heterotrophs and ingest food by phagocytosis while other types of protists are photoautotrophs and store energy via photosynthesis. Those that store energy by photosynthesis belong to a group of photoautotrophs and are characterized by the presence of chloroplasts.

Loosely a monophyletic taxon is one that includes a group of organisms descended from a single ancestor whereas a polyphyletic taxon is composed of unrelated organisms descended from more than one ancestor. Which of these groups includes species that produce a substance that is toxic to humans. Eukaryotes that are not plants animals or fungi.

A Paramecium waves hair-like appendages called cilia to propel itself. Concepts of monopoly polyphyly paraphyly. Amoebas and some other heterotrophic protist.

- Endoplasmic reticulum ER and nuclear envelope. Other protists are heterotrophic and consume organic materials such as other organisms to obtain nutrition. - Nuclear envelope and mitochondria.

Four are plants and two are animals. Protists use various methods for transportation. Of the six kingdoms now recognized answer choices.

Many of the protists in this clade could be described as amoebas. This group includes the slime molds gymnamoebas and entamoebas. Protists are unicellular organisms belonging to eukaryotic cells but they are simpler than many eukaryotes.

Sexual reproduction in plant-like protists is similar to sexual reproduction in other eukaryotes. Identify the common characteristics of protists. They were among the first animals to live on land and their diversity is greater than all living things known.

Since many protists live in symbiotic relationships with other organisms and these relationships are often species specific there is a huge potential for undescribed protist diversity that matches. Protists contain very organized structures in their cells called organelles which perform many complex functions. There are over 100000 described living species of protists and it is unclear how many undescribed species may exist.

The two best known types of euglenozoans are kinetoplastids with their single large mitochondrion and the euglenids which include euglenas. A eukaryotic organism that lacks the characteristics necessary to be classified with animals plants or fungi is a n _____. Animal-like protists fungus-like protists and plant-like protists.

Most protists are microscopic and unicellular but some true multicellular forms exist. Protists may have animal-like cell membranes plant-like cell walls or may be covered by a pellicle. Two are eukaryotes and four are prokaryotes.

Still other protists are composed of enormous. 16 The position of mammals in evolution is best described as 1 pts they dominate life in the sea. Two are prokaryotes and four are eukaryotes.

Since protists vary so much we will group them into three subcategories. Which of the following best describes protists. - Mitochondria and chloroplasts.

Protists exhibit many forms of nutrition and may be aerobic or anaerobic. Slime molds were originally grouped in with fungi because they produce. There are over 100000 described living species of protists and it is unclear how many undescribed species may exist.

View the full answer. - Endoplasmic reticulum ER and ribosomes. Most protists are motile and generate movement with cilia flagella or pseudopodia.

The clade known as _____ inlcudes red and green algae as well as land plants. __________ is a protist that causes late blight of potatoes and was responsible for the. Amoebozoans are amoeba protists that have lobed or tube-shaped pseudopodia.

Several diverse groups of photosynthetic protists. Four are bacteria and two are eukarya. B Amoeba uses lobe-like pseudopodia to anchor itself to a solid surface and pull itself forward.

There are over 100000 described living species of protists and it is unclear how many undescribed species may exist. APES Chapter 11 and 20 PT 2.
