These chloroplasts are surrounded by three membranes and contain chlorophylls A and C, along with other pigments, so are probably derived from a captured green alga.

Paramecium bursaria, a species of ciliate, has a mutualistic symbiotic relationship with green alga called Zoochlorella.

:* Chlamydomonas reinhardtii-a unicellular green alga used to study photosynthesis, flagella and motility, regulation of metabolism, cell-cell recognition and adhesion, response to nutrient deprivation and many other topics.

These sequences have been used to make a comparative analysis between P. tricornutum and the putative complete proteomes from the green alga Chlamydomonas reinhardtii, the red alga Cyanidioschyzon merolae, and T. pseudonana.

The heterotrophic protist Hatena behaves like a predator until it ingests a green alga, which loses its flagella and cytoskeleton, while Hatena, now a host, switches to photosynthetic nutrition, gains the ability to move towards light and loses its feeding apparatus.

* Chara elegans, a green alga species

The strip of a green alga ( Enteromorpha ) along this shore indicates that there is a nearby source of nutrients ( probably nitrates or ammonia from a small estuary ).

But in many unicellular ( e. g. the ciliate Tetrahymena or the green alga Chlamydomonas reinhardtii ) and in rare cases also in multicellular organisms ( e. g. in some species of Cnidaria ) the mtDNA is found as linearly organized DNA.

The lake waters may be pinkish due to high concentrations of β-carotene in the halophyte green alga Dunaliella salina.

Complex plastids start by secondary endosymbiosis, when a eukaryote engulfs a red or green alga and retains the algal plastid, which is typically surrounded by more than two membranes.

Those that endosymbiosed a green alga include the euglenids and chlorarachniophytes (= chloroplasts ).

are composite organisms consisting of a symbiotic relationship between a fungus ( the mycobiont ) and a photosynthetic partner ( the photobiont or phycobiont ), usually either a green alga ( commonly Trebouxia ) or cyanobacterium ( commonly Nostoc ).

If a cyanobacterium is present, as a primary partner or another symbiont in addition to green alga as in certain tripartite lichens, they can fix atmospheric nitrogen, complementing the activities of the green alga.

The glaucophytes are of interest to biologists studying the development of chloroplasts because some studies suggest that they may be similar to the original alga type that led to green plants and red algae.

The chloroplasts were presumably acquired by ingesting some green alga.

Studies of the genomic organization and of the molecular phylogeny have shown that the nucleomorph of the cryptomonads formerly was the nucleus of a red alga, whereas the nucleomorph of the chlorarchniophytes formerly was the nucleus of a green alga.

After the red or green alga was engulfed by its host cell, it was reduced.

The unique combination of host cell and complex plastid results in cells with four genomes: two prokaryotic genomes ( mitochondrion and plastid of the red or green alga ) and two eukaryotic genomes ( nucleus of host cell and nucleomorph ).

The green algae ( singular: green alga ) are the large group of algae from which the embryophytes ( higher plants ) emerged.

Chlamydomonas is a genus of green algae consisting of unicellular flagellates.

It is conserved in all organisms containing thylakoids, including cyanobacteria, green algae, such as Chlamydomonas, and higher plants, such as Arabidopsis thaliana.

* Some green algae, e. g. Chlamydomonas

Among eukaryotes, selenoproteins appear to be common in animals, but rare or absent in other phyla ( one has been identified in the green alga Chlamydomonas, but none in other plants or in fungi ).

Chlamydomonas reinhardtii is a single celled green alga about 10 micrometres in diameter that swims with two flagella.

Chlamydomonas reinhardtii and some other green algae can, under specified circumstances, stop producing oxygen and convert instead to the production of hydrogen.

Flow cytometric analysis of the cadmium-exposed green algae Chlamydomonas reinhadtii ( Chlorophyceae ).

The most researched CVs belong to the protists Paramecium, Amoeba, Dictyostelium and Trypanosoma, and to a lesser extent the green alga Chlamydomonas.

The sand is fine and pleasant, the cabanas are clean, and the parasols, green, raspberry, and butter yellow, are very gay.

Around that statue in the green park where children play and lovers walk in twos and there is a glowing view of the whole city, in that park are the rows of marble busts of Garibaldi's fallen men, the ones who one day rushed out of the Porta San Pancrazio and, under fire all the way, up the long, straight narrow lane to take, then lose the high ground of the Villa Doria Pamphili.

Falling somewhere in a category between Einstein's theory and sand fleas -- difficult to see but undeniably there, nevertheless -- is the tropical green `` city '' of Islandia, a string of offshore islands that has almost no residents, limited access and an unlimited future.

When different colors are used, she is just as likely to color trees purple, hair green, etc..

It is roughly shaped like a large pear, and when properly ripened, its dark green skin covers a meaty, melon-like pulp that has about the consistency of a ripe Bartlett pear, but oily.

This is not necessarily to green, however, for in some situations only a yellow indication is given to a train to let it into the `` plant ''.

In other instances where there is no automatic block signaling, the distant has only green and yellow aspects.

The video signal is amplified and then switched, in synchronism with the three ultraviolet light sources which are sequenced by the rotating mirror so that during one-twentieth of a second only one wavelength, corresponding to red, green, or blue, is seen.

But now that all production builders build with drywall and all smart builders build with panels, green lumber is an anachronism you cannot afford.

It is not difficult to see that the stamens of the catkin are always arranged in pairs, and that each individual flower is nothing but one such pair standing on a green, black-tipped little scale.

He said `` Morris County is rapidly changing and unless steps are taken to preserve the green areas, there will be no land left to preserve ''.

" Anaconda " is often used to refer only to the green or common anaconda, Eunectes murinus.

Although the name actually applies to a group of snakes, it is often used to refer only to one species in particular, the common or green anaconda, Eunectes murinus, which is one of the largest snakes in the world.

** Eunectes murinus, the green anaconda, the largest species, is found east of the Andes in Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil and on the island of Trinidad.

As an example, heavier halogens are darker than are halogens of lesser atomic weight – fluorine is nearly colorless, chlorine is bright green, bromine is brown, and iodine is dark gray / violet.

Poirot has dark hair, which he dyes later in life ( though many of his screen incarnations are portrayed as bald or balding ), and green eyes that are repeatedly described as shining " like a cat's " when he is struck by a clever idea.

The inner shell of the abalone is an iridescent swirl of intense colours, ranging from deep cobalt blue and peacock green to purples, creams and pinks.

The tower is decorated with monograms of Jesus ( JHS ), Maria ( M with the ducal crown ) and Joseph ( JHP ), made ​​ of ceramic pieces that stand out golden on the green background that covers the facade.
