Bunch of answers:

-The thing in the picture is a 𝘚𝘺𝘳𝘪𝘯𝘨𝘢𝘮𝘮𝘪𝘯𝘢 𝘧𝘳𝘢𝘨𝘪𝘭𝘪𝘴𝘴𝘪𝘮𝘢, a kind of Xenophyophorean, which are specialized foraminiferans known for making funky tests (shells) out of sediments. It has no relationship to plants and can't photsynthesize, not sure where you gor that from :)

-SARS viruses have no relationship to the SAR clade. SARS stands for Severe Acute Respiratory Syndrome whereas (T)SAR is just the initials of its majour groups. The name similarity is a complete coincidence.

-S: Stramenopiles is a diverse group of organisms also called Heterokonts (greek for different flagella), as most have at one point of their life cycle 2 flagella, one with and one without "little hairs" on top of the flagellum and the length is also different. Some notable representatives:

• Oomycetes, also known as pseudofungi, which are organisms that look quite a bit like fungi (they form hyphae and micelia) but have no relationship at all. Some are saprophytes whereas others are parasites of plants and fish, including potato blight, the organism that caused the Irish Potato Famine

• Diatoms: Unicellular algae which form very beautifully patterned shells out of silica (so glass), and are very abundant.

• Brown algae: Brown algae have no relationship to plants or other algae. Unlike plants and red and green algae, which acquired their chloroplast from a primary endosymbiosis event with a cyanobacteria, brown algae and many other unicellular algae acquired their chloroplasts by undergoing endosymbiosis with 𝘢𝘯𝘰𝘵𝘩𝘦𝘳 already existing alga. (look into endosymbiosis theory if u have no idea whats going on here)

-A: Alveolata are organisms which have a kind of sacs made of membrane under their main membrane called alveoli. They are also incredibly diverse. They include

• Dinoflagellates: A kind of algae which (in some cases) modified their alveoli to fill them up with cellulose and form a kind of shell. They have funky shapes and are often abundant in the sea. Some of them are known for causing massive blooms which turn the sea red (red tides) and can cause food poisoning if you eat seafood from where a bloom happened.

• Ciliates: Organisms known for having lots of cilia on their bodies, won't go into them because they're very diverse and different, but you can think of a 𝘗𝘢𝘳𝘢𝘮𝘦𝘤𝘪𝘶𝘮 for a typical example of a ciliate.

• Apicomplexans: Mostly parasitic organisms which have a sort of "complex" on the tip of the cell which helps them inject themselves into other cells, this includes the organism which causes malaria, 𝘗𝘭𝘢𝘴𝘮𝘰𝘥𝘪𝘶𝘮.

-R: Rhizaria are amoeboid organisms which often have long pseudopodia called filopodia and are, who would've guessed, also very diverse. The most well known of them are

•Formanifera: A group of mostly marine organisms which form single or multi-chambered shells which can get very complex and are abundant in the sea, so much so that if you know which foraminifera lived in which time periods, you can use their shells in marine sediments to assign a date to them.

• Radiolarians: Organisms which are known for making very intricate and beautiful shells which are very diverse in shape. Look up some of Ernst Haeckel's illustrations of Radiolarians.

-T: Regarding the Telonemia, very few species are described and they aren't very well known, but genetic analysis placed them close to the SAR clade so the acronym is sometimes extended to TSAR

Hope all this helps

THANK YOU SO MUCH MY DUDE THIS IS AN AMAZING ANSWER AHAHAHAHA

^this is why I thought they were related to plants, because both SAR and plants / plant-related things are in this clade, and it says most of the organisms which can photosynthesise are in this clade. But I misunderstood it, thinking it meant most of the organisms that are in this clade can photosynthesise. So, SAR can’t photosynthesise. Is this article wrong to say SAR and plants are related?

Ok so I found this article, which has this tree of life in it-

Which suggests plants and TSAR are very loosely related in that they’re closer than eg opisthokonts. And this was in 2020 so is probably fairly close to how things are modernly. (I haven’t fact checked this article. I hope it’s mostly true…)

ANYWAYS

If the xenophyophore makes itself a shell, is that what you can see in the photo? Is the organism itself smaller than the shell or does it fill it? The shell is made of sediment, is it the texture of sediment? All squishy? Or is it shell-ish?

What does saprophyte mean? (Nvm I googled it, it means something which munches upon dead things to survive)

OH DIATOMS SOUND SO COOL!! Kinda like glass sponges but tiny algae!!

oh wowwww they’re stunning! gorgeous! i love them! beautiful! new favourite organism!

i am thrilled by the fact that plants get their chloroplasts from cyanobacteria. I did not know that. Everything relies on cyanobacteria?!?! Where do cyanobacteria get their chloroplasts from btw?

do the alveoli contain the rest of the cell or are they just empty? what’s in the alveoli? Does that just depend on what specific alveolate it is or do most alveoli have a similar function?

arcan, I.T. department (again) ㅡ monday afternoon, 20171009

Se tinha duas coisas que Jaehyun com certeza era, essas coisas eram bondoso e aleatório. Quando ambas as características tinham um ponto de encontro... O resultado geralmente era bem curioso. Nesse caso, era o aniversário (quer dizer, já tinha passado, mas finge) de Dimitri, e por causa da simpatia que sentia pelo mais novo, é claro que o designer fez questão de arrumar um presente para o mesmo. Gostava de presentear pessoas, gostava mais ainda de comprar coisas bem diferentes como presente, e o belo exemplar de um dinopet que carregava em baixo do braço enquanto caminhava para o departamento de tecnologia da informação era um dos melhores exemplos disso.

Chegando sorrateiramente por trás de Dimitri, pegou uma cadeira de rodinhas próxima e se sentou, deixando a caixinha embrulhada no próprio colo e dando um impulso com os pés para deslizar para perto da mesa do rapaz, exatamente ao lado dele, parando muito suavemente com os cotovelos apoiados na superfície, as mãos emoldurando o próprio rosto e um sorrisinho colgate adorável no mesmo. ㅡ Feliz aniversário atrasado, Dimitri-ssi! ㅡ Disse, no seu melhor tom de voz alegre, logo pegando o presente e pousando em cima da mesa, o papel pardo simples do embrulho chamando a atenção por causa dos muitos doodles feitos ali à mão pelo de cabelos azulados. ㅡ Eu espero que você goste, porque eu achei o máximo. ㅡ Riu breve, pondo-se a esperar um tanto ansioso para que o mais novo abrisse a caixa. Era difícil disfarçar a empolgação, mas ainda assim existia a insegurança de sempre fazendo-o ter medo de desagradar.
