Is Trichomonas vaginalis an Autotroph?
Table of Contents
Parasite. Heterotrophic protists that have modified mitochondria and generate some energy anaerobically. Trichomonas vaginalis. Can be heterotrophs, photosynthetic autotrophs, and pathogenic parasites.
Is Unikonta photosynthetic?
The Eucarya are now classified into about five major groups: Unikonta (including amoebozoans, animals, and fungi), Excavata (Diplomonads, etc.), Rhizaria, Chromalveolata (a large and possibly heterogeneous group including ciliates, brown algae, and many others), and Archaeplastida (a group of photosynthetic organisms …
Is paramecium a photosynthetic protist?
Paramecium (non-photosynthetic protist) – Paramecium is a common protozoan that uses cilia for locomotion and feeding.
What organisms are 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.
Is Excavata a phylum?
Excavata is a major supergroup of unicellular organisms belonging to the domain Eukaryota….Excavata.

What do photosynthetic organisms produce?
Photosynthetic organisms, known as photoautotrophs, capture the energy from sunlight and use it to produce organic compounds through the process of photosynthesis. In photosynthesis, the inorganic compounds of carbon dioxide, water, and sunlight are used by photoautotrophs to produce glucose, oxygen, and water.
What includes Excavata?
Excavata includes the protists: Diplomonads, Parabasalids and Euglenozoans. Diplomonads are defined by the presence of a nonfunctional, mitochrondrial-remnant organelle called a mitosome.
Where are Excavata found?
Malawimonads. The malawimonads are generally considered to be members of Excavata owing to their typical excavate morphology, and phylogenetic affinity to other excavate groups in some molecular phylogenies. However, their position among eukaryotes remains elusive.
What are non photosynthetic protists?
Phycokey – Non-photosynthetic protists. Flagellates and ciliates are polyphyletic protists conveniently placed in two groups based on their means of motility. Some are photosynthetic, many or most are heterotrophic phagotrophs.
Are all Archaeplastida photosynthetic?
Archaeplastida (‘ancient plastids’) are the group containing essentially all of the primary algae (i.e., with plastids of primary endosymbiotic origin – see above), and the great majority of living species in this assemblage are photosynthetic.
What are the characteristics of Unikonta?
Characteristics. The unikonts have a triple-gene fusion that is lacking in the bikonts. The three genes code for enzymes which make pyrimidine nucleotides. This must have involved a double gene fusion, a rare pair of events, which supports the shared ancestry of Opisthokonta and Amoebozoa.
