Which group contains prokaryotes able to live in extreme environments like salt ponds?

Archaea are unicellular, prokaryotic microorganisms that differ from bacteria in their genetics, biochemistry, and ecology. Some archaea are extremophiles, living in environments with extremely high or low temperatures, or extreme salinity. Only archaea are known to produce methane.

Which group of protists has many species with modified mitochondria that lack functional electron transport chains?

diplomonads
The diplomonads have modified mitochondria (called mitosomes) that lack functional electron transport chains and thus are unable to perform cellular respiration so they derive their energy from pathways such as glycolysis.

What group includes protists that reside within the cells of corals?

Most corals contain algae called zooxanthellae (pronounced zo-UH-zan-thuh-lay), which are plant-like organisms. Residing within the coral’s tissues, the microscopic algae are well protected and make use of the coral’s metabolic waste products for photosynthesis, the process by which plants make their own food.

Which group of protists are Autotrophs?

Autotrophic protists–those that, like plants, use photosynthesis to make their own food–are called algae. These include red, brown and green algae, as well as diatoms, dinoflagellates and euglena. Some algae have complex life cycles; plant life is thought to have evolved from green algae.

Are protists Autotrophs or Heterotrophs?

Protists get food in many different ways. Some protists are autotrophic, others are heterotrophic. Recall that autotrophs make their own food through photosynthesis or chemosynthesis (see the Photosynthesis concepts). Photoautotrophs include protists that have chloroplasts, such as Spirogyra.

What are the 4 main protists?

The Protozoa is often divided into 4 phyla : Amoebalike protists, flagellates, ciliates, and spore-forming protists.

What group of protists is thought to be the main source of Earth’s oil deposits quizlet?

What group of protists is thought to be the main source of Earth’s oil deposits? Diatoms are thought to be the main source of oil, whereas coal was formed from primitive plants.

Which of the following domains contains prokaryotes that inhabit extreme environments such as salt ponds or hot springs?

1. All prokaryotic organisms can be divided into two domains: the Archaea and the Bacteria. Members of the Archaea dominate harsh environments such as hot springs, salt flats, and anaerobic mud flats, and they also are found in more equable habitats.

What domain of organisms describes groups of prokaryotes that tend to live in extreme environments?

The domains Bacteria and Archaea are the ones containing prokaryotic organisms. The Archaea are prokaryotes that inhabit extreme environments, such as inside of volcanoes, while Bacteria are more common organisms, such as E. coli.

Which protist group have modified mitochondria?

diplomonads
Two groups of protists (the diplomonads and the parabasalids) have highly modified mitochondria. The evidence suggests that each group is monophyletic but what is less clear is how closely related these two groups are to each other.

Which of the following clades of protists consist of modified mitochondria?

The two clades with modified mitochondria are the diplomonads and the parabasalids. The diplomonads include the common and unpleasant water -borne intestinal parasite Giardia.

Do photosynthetic protists have mitochondria?

They also have specialized cellular machinery called organelles that execute defined functions within the cell. Photosynthetic protists such as the various types of algae contain plastids. … Most protists have mitochondria, the organelle which generates energy for cells to use.

Which group includes many protists with Filose Pseudopodia?

Rhizarian amoeba are amoeboids with filose, reticulose, or microtubule-supported pseudopods and include the groups: Cercozoa, Foraminifera, and Radiolaria and are classified as bikonts.

Is dinoflagellates photosynthetic or heterotrophic?

Not all dinoflagellates are photosynthetic, particularly large open water pelagic species belonging to the genera Protoperidinium and Gymnodinium which can be holozoic. Nearly half of the known extant dinoflagellate species are heterotrophic.

Which of the following groups includes the genus Trypanosoma?

among red blood cells. Trypanosoma is a genus of kinetoplastids (class Trypanosomatidae), a monophyletic group of unicellular parasitic flagellate protozoa. Trypanosoma is part of the phylum Sarcomastigophora. The name is derived from the Greek trypano- (borer) and soma (body) because of their corkscrew-like motion.

Which of the following groups includes protists that cause red tide?

The protist that causes red tides are dinoflagellates. There are many types of dinoflagellates, but only some are able to cause red tide.

Are protists eukaryotic or prokaryotic?

protist, any member of a group of diverse eukaryotic, predominantly unicellular microscopic organisms. They may share certain morphological and physiological characteristics with animals or plants or both.

Which type of protist forms a symbiotic relationship with corals?

zooxanthellae
Protists like zooxanthellae have a symbiotic relationship with coral reefs; the protists act as a food source for coral and the coral provides shelter and compounds for photosynthesis for the protists.

Which term describes autotrophic protists?

The largest group of autotrophic protists is collectively called algae. We can break the algae down into more specialized groups based on the shape of their cells and the type of photosynthetic pigments they use. The most common examples are green algae, red algae, brown algae, and golden algae.

Which of the following is autotrophic Protista *?

Gonyaulax (a dinoflagellate) and diatoms are autotrophic protists with cell walls. Physarum is a slime mould which is heterotrophic.

Which of the following is autotrophic protist?

Algae is an autotrophic protist.

What protists are autotrophic and heterotrophic?

Euglena is autotrophic and heterotrophic both.

Do protists include heterotrophs?

For classification, the protists are divided into three groups: Animal-like protists, which are heterotrophs and have the ability to move. Plant-like protists, which are autotrophs that photosynthesize. Fungi-like protists, which are heterotrophs, and they have cells with cell walls and reproduce by forming spores.

Are most protists heterotrophs?

Protista shows different types of mode of nutrition like photosynthetic, holozoic, saprobic, parasitic and mixotrophic. Therefore all Protists are not heterotrophs. Protista show similarities or link with other kingdoms, therefore it has different modes of nutrition.

What are the 3 groups of protists?

Protists are typically divided into three categories, including animal-like protists, plant-like protists, and fungus-like protists. Protists vary in how they move, which can range from cilia, flagella, and pseudopodia.

  • Dianoflagellates. These organisms are usually marine and photosynthetic. …
  • Euglenoids. These are mostly freshwater organisms. …
  • Slime Moulds. Slime moulds are saprophytic protists. …
  • Protozoans.

What are the 3 main groups of Kingdom Protista?

Protists are a diverse kingdom, including all eukaryotic organisms that are neither animals, nor plants, nor fungi. For classification, the protists are divided into three groups: animal-like protists, plant-like protists, and fungi-like protists.

Which of these is the group of Chromalveolates that includes diatoms kelp and oomycetes?

Stramenopiles: Diatoms, Brown Algae, Golden Algae and Oomycetes. The other subgroup of chromalveolates, the stramenopiles, includes photosynthetic marine algae and heterotrophic protists. The chloroplast of these algae is derived from red alga.

What evidence supports the hypothesis mitochondria and plastids evolved from prokaryotic endosymbionts?

There is broad evidence to show that mitochondria and plastids arose from bacteria and one of the strongest arguments to support the endosymbiotic theory is that both mitochondria and plastids contain DNA that is different from that of the cell nucleus and that they have their own protein biosynthesis machinery.

Which of these groups consist of parasitic flagellated cells?

Which of these groups consist of parasitic flagellated cells, such as Trypanosoma, the organism that causes sleeping sickness? Parasitic flagellated cells, such as Trypanosoma, are classified as kinetoplastids.
