LECA, the last eukaryotic common ancestor. it's a species of single celled organism that lived like 1-2 billion years ago and probably had a nucleus, mitochondria, and it fucked
LECA

Did LECA require cyanobacteria!
LIGHTWEIGHT EXPANDED CLAY AGGREGATE would NOT EXIST without Cyanobacteria, but the LAST EUKARYOTIC COMMON ANCESTOR WOULD.
Let's start with the first LECA. Clay is formed from hydrous aluminum phyllosilicates, which are minerals. Although clay did exist before Cyanobacteria did, the atmospheric O2 which Cyanobacteria created causing the Great Oxygenation Even did cause an increase in the amount of clay on Earth, as Clay contains Oxygen and cannot be formed without it. Lightweight Expanded Clay Aggregate however could not exist without Cyanobacteria, because all organisms capable of creating the rotary kilns needed to produce it breathe atmospheric O2 as well, almost all of which was produced by Cyanobacteria in the aforementioned GOE. I think this ask might be talking about the other LECA though. The Last Eukaryotic Common Ancestor would exist without Cyanobacteria. This organism, which lived about 2.2 billion years ago, was the ancestor of all Eukaryotes and was formed through the symbiogenesis of an archaeon and a bacterium. Although this did happen at the same time as the GOE, neither the archaeon nor the bacterium which came to form the first eukaryote exclusively breathed O2. The archaeon was likely anerobic (did not breathe O2), and the bacterium was facultatively aerobic (could breathe O2, but didn't have to). It is worth nothing however, that most modern Eukaryotes do exclusively breathe the O2 produced by Cyanobacteria, and that quite a portion of modern Eukaryotes actually contain Cyanobacteria (although LECA did not).
Hello! My name is Sarah. I'm a 33 year old Colorado mom sharing her love for indoor plants with her son. I worked for three years as a cannabis grow lead. After leaving said job, I brought my passion home with beautiful various plants instead. This blog is my collection of notes, pictures, and progress. I'm sharing them because I don't have other plant lovers in my circle, so feel free to interact!
I'm super proud of myself for finally getting my Pink Princess Philodendron repotted with a much needed moss pole. It was definitely a challenge holding her and doing everything by myself, but slow and steady won the race. Her roots were gorgeous and will thrive in this ten inch pot. I had to turn her because her leaves had all turned one way for its light source. I should probably rotate her more 😅
Next up:
Algaonema needs to be split and repotted or repotted + supported
Philodendron Birkin needs to be split and repotted | Has two mature and two babies in current pot from nursery
Anyone have any soil mixture recommendations? I currently make my own blend but am curious as to what others use!
I grow my houseplants in a semi hydro setup, in LECA.
This type of post is lovingly called root porn in the semi hydro community XD
Philodendron Billietiae, Alocasia Frydek, Syngonium Albo, and 2 separate Syngonium Mojitos however one has lost it’s variegation. )’:
Part 2 after the jump.

O sábio nunca se assume sábio, porque sabe, pela sua sapiência, que ainda tem muito que aprender.
O arrogante, por sua vez, arrota que muito sabe e que a verdade é a coisa mais óbvia de sua vida. Mas no fundo vive apavorado de ser pego e atormentado pela dúvida em saber que pode ser descoberto.
E os que não são sábios ou arrogantes, orbitam um deles. E é assim que vejo as pessoas hoje, mascaradas por perfis midiáticos, escondidas de suas reais características, porque a internet nos dotou dessa facilidade: a máscara.
Qual o foco, o ponto lá na frente, o lugar que se quer chegar, com tanta discussão? Com tanto empenho em se mostrar certo? É tão errado assim errar?
E essa rotina desgastante vem me afastando do momento, da mídia, da rua, das pessoas. Ver lutas vãs minam o que ainda me resta de fé nos outros, e enfraquece a fé em mim mesma. E com a fé fragilizada fica difícil ficar de pé, erguida, pronta.
Gosto de ser frágil quando isso me leva a me despir frente a quem amo, me mostrar como sou, sem receio de ser julgada ou lida em outro idioma. Mas me fragilizar por falta de forças, por me sentir só, por ser traída em ideais, isso sim é triste.
Saudades de acreditar, de me sentir fazendo a diferença, de socializar com sorrisos mas também com lágrimas, de ser peça importante na construção de uma história, seja ela qual for. Saudades de ser forte... Porque hoje todos somos muito frágeis, mesmo com cascas à mostra.

my gloriosum had a hard transition into leca, i’m hoping letting it grow some water roots will help🤞🏻
