What type of protist is Zooxanthellae?
Zooxanthellae is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs.
Which are Saprophytic protists?
Saprophytic protists are organisms that release enzymes into the surrounding which convert organic matter into a simpler form that will be absorbed by the body surface of the organism.
Is Chromista a protist?
Chromista is a biological kingdom consisting of single-celled and multicellular eukaryotic species that share similar features in their photosynthetic organelles (plastids). It includes all protists whose plastids contain chlorophyll c, such as some algae, diatoms, oomycetes, and protozoans.
What is an example of a multicellular protist?
Seaweed and kelp are examples of multicellular, plant-like protists. Kelp can be as large as trees and form a “forest” in the ocean (Figure below). Macrocystis pyrifera (giant kelp) is a type of multicellular, plant-like protist.
What are the 3 categories of protists?
Summary
- 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.
Are all protists Mixotrophic?
Not all protists are Mixotrophic. Some are heterotrophs, such as amoeba, paramecium, and sporozoans. Many others are autotrophs – like algae. However, current research has shed light that some protists plankton exhibit phototrophy as well as phagotrophy – making them mixotrophs.
Is Gonyaulax saprophytic?
D)Gonyaulax. Hint: Sludge molds are termed as the saprophytic protists. The body shows movement along rotting twigs and leaves immersing natural material. Under reasonable conditions, they give rise to a collection of structures called Plasmodium which may develop and spread more than a few feet.
Are protists Saprophytes?
These “plant-like” (autotrophic) organisms are composed mostly of unicellular algae. The dinoflagelates, diatoms and Euglena-like flagellates are photosynthetic protists. “Mold” generally refer to fungi; but slime molds and water molds are “fungus-like” (saprophytic) protists, although some are pathogens.
How are protozoans different from Chromists?
How are protozoans different from Chromists? Protozoa are animal-like, heterotrophic, usually motile. [5] Molecular evidences indicate that the plastids in chromists were derived from red algae through secondary symbiogenesis in a single event.
What kingdom is Phaeophyta in?
Chromista
Brown algae/Kingdom
What are multicellular protists?
Multicellular protists are found within different groups of algae, and during one life stage of the slime molds. All protists have eukaryotic cells, meaning cells that have a defined nucleus enclosed in some type of membrane, but green, brown, and red algae are plant-like protists.
