Protozoa Pictures is an American production company founded in 1997 by American filmmaker Darren Aronofsky, headquartered in New York City. It is mainly a handle for Aronofsky's filmography, but has financed other projects alongside Aronofsky's.

Protozoans are tiny single-celled organism found in freshwater and marine habitats. This diverse group of organisms vary in shape, size and features. View this extensive image gallery of protozoan taken using different imaging techniques including scanning electronic micrographs, transmission electron micrograph and light micrographs.
Category. : Protozoan. From Wikimedia Commons, the free media repository. English: Protozoa (from the Greek words πρωτό, proto, meaning first, and ζωα, zoa, meaning animals; singular protozoon or also protozoan) are a diverse group of single-cell eukaryotic organisms, many of which are motile.

Organisms known as protozoa include a wide range of organisms, most of which are free-living single-celled eukaryotes. Therefore, protozoa fit into the Domain Eukarya. Although the different phyla of the kingdom Protista are not closely related, they are nonetheless classified together because of their large differences from the other kingdoms of p...
An interesting phenomena in the ocean is also caused by another phylum of protozoa. The Dinoflagellates are a group of protozoa that exist mainly as free-swimming unicellular organisms, while other exist symbiotically within certain invertebrates. Groups of dinoflagellates that are free swimming can undergo drastic periods of reproduction, known as...
The Euglenida are a phylum of protozoa recognized by the pellicle that gives them shape and the flagella which they use for locomotion. The pellicle is a shell of sorts that exists beneath the cell membrane. It is composed of strips of proteins, which interlock for support. Some organisms in the Euglenida are photosynthetic, and contain chloroplast...
Closely related to the Euglenida, the Kinetoplastida are also protected by a pellicle, although it is made exclusively of microtubules. Organisms in the Kinetoplastida share the unique characteristic of having a single, much enlarged and elongated, mitochondrion. Typically, cells have many small mitochondria, as opposed to one large one. The Kineto...
Instead of flagella for locomotion, organisms in the phylum Ciliophora use much smaller structures called cilia. The cilia of these organisms cover their entire cell, and work together to propel the cell forward. Much like the individual paddles of a row boat, each cilia gives a forward moving power stoke, then whips back to the starting position i...
As seen in Example #1, the Apicomplexa include mostly parasitic organisms that exist solely within their host organisms. These organisms all have apical complexes, which allow them to gain entry into their hosts cells. Inside the cells, the parasites are much more resistant and have better access to nutrients. Many of these parasites can also chang...
The organisms in Actinopoda have characteristic axopodia, which are sharp spines that extend from the cell and are covered in cytoplasm. They are used in locomotion and feeding. The axopodia also produce beautiful shapes, as seen in the organism below:
The Diplomonodida are a phylum of organisms that have many flagella for locomotion. The average number is around 8. While there are many species that vary in their place in the ecosystem, the most well-known of these protozoa is the genus Giardia, which can be consumed in unclean water and cause flu-like symptoms and diarrhea in humans.
Several other phyla of protozoa exist, but cannot be covered here. Like all other protozoans, these organisms lack specialized tissues or layers of cells. Most are unicellular, although some exist in colonies or fibers. Due to their small size an adaptability, the protozoa have occupied nearly every environment on the planet.
1. A scientist is watching an unknown organism develop. As the cells divide, they begin to form distinct tissue layers. Which of these describes the organism?
Protozoa Pictures fue una compañía creada en 1997 en New York conocida por Réquiem por un sueño, Cisne negro, El luchador, Madre!, La ballena (The Whale), Pi, fe en el caos, Nuestro Planeta (Serie de TV), Sin límites con Chris Hemsworth (Serie de TV), Parentesco (Miniserie de TV) y Amazonas: territorio límite.
Protozoa ( sg.: protozoan or protozoon; alternative plural: protozoans) are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris. [1] [2] Historically, protozoans were regarded as "one-celled animals".
