What are examples of Chromalveolata?

Chromalveolates include very important photosynthetic organisms, such as diatoms, brown algae, and significant disease agents in animals and plants.

What kingdom is Chromalveolata?

Chromalveolata was an eukaryote supergroup present in a major classification of 2005, then regarded as one of the six major groups within the eukaryotes. It was a refinement of the kingdom Chromista, first proposed by Thomas Cavalier-Smith in 1981.

Are Chromalveolata unicellular or multicellular?

Cyclospora and Cystoisospora are both unicellular parasites from the Chromalveolata supergroup within eukaryotes belonging to the Coccidiasina protist group, known as Apicomplexa (Levine et al., 1980; Cox, 1993; Adl et al., 2005).

What is Chromalveolata in biology?

Chromalveolata (krom-al-ve-o-LA-tuh) is formed from two roots (one Greek and the other Latin) that mean “color” (chroma -χρώμα) and a small cavity (alveolus). The references are to the bag-like sacs that underlie the cell membrane and that many taxa are pigmented (photosynthetic).

Which of the following group’s is included under Chromalveolata?

The Chromalveolata comprises four monophyletic groups—Alveolata, Cryptophyta (plus Katablepharidae) [8], [28], Haptophyta, and Stramenopiles, each group containing at least some members harboring plastids thought to be derived from a red alga by secondary endosymbiosis [10].

Are stramenopiles fungi?

Stramenopiles are eukaryotes; since they are neither fungi, animals, nor plants, they are classified as protists. Most stramenopiles are single-celled, but some are multicellular algae including some brown algae.

Are Rhizarians algae?

Rhizaria also contains two small groups of photosynthetic organisms, one of which is the chlorarachniophyte secondary algae discussed above (Figure 5(c)), while the other is a tiny group of filose testate amoebae (see below) from the genus Paulinella, which have photosynthetic organelles that derived from cyanobacteria …

Are Excavata unicellular or multicellular?

unicellular organisms
Excavata is a major supergroup of unicellular organisms belonging to the domain Eukaryota.

Which group of chromalveolata is armored with cellulose plates?

Figure: Dinoflagellates: The dinoflagellates exhibit great diversity in shape. Many are encased in cellulose armor and have two flagella that fit in grooves between the plates.

Are stramenopiles protozoa?

However, the stramenopile clade also contains numerous lineages of protozoa, most of which are small bacterivorous flagellates (see Patterson, 1999; Massana et al., 2014; Figure 4(h)).

Are stramenopiles protists?

Are amoeba Rhizarians?

The best-known rhizarians – Foraminifera (Figure 5(a)), the radiolarians, and the filose testate amoebae – are all amoebae of this kind, but in addition usually have self-mineralized shells (tests) or ‘skeletons,’ which are made of calcium carbonate, strontium sulfate or silica, depending on the group or subgroup (e.g. …

Which of the following group’s is included under chromalveolata?

Are Excavata multicellular?

Excavata is a major supergroup of unicellular organisms belonging to the domain Eukaryota.

What species is Excavata?

Excavata are a supergroup of protists that are defined by an asymmetrical appearance with a feeding groove that is “excavated” from one side; it includes various types of organisms which are parasitic, photosynthetic and heterotrophic predators.

What separates Dinophytes from other algae?

Some species also produce potent neurotoxins. At the ultrastructural level, dinoflagellates have a common thecal or cell covering structure that, along with their flagellar and nuclear characters, differentiates them from other algal groups.

What do stramenopiles include?

Stramenopiles (also called the heterokonts) are a vast and complex group of organisms that consist of both photosynthetic and nonphotosynthetic cell types as well as unicellular and multicellular species (Andersen, 2004).
