I didn't explain.

The lycophyte is very important role in history of planet Earth during Silurian period 🤢

This condition exists today in some lower vascular plants (Figure 19.25) and a few angiosperms, such as certain cacti.

Whilst you were out touching grass, I was touching moss you fool!

None of you thought it might be important to tell me that ferns have sperm that swim???

So.

None of you thought it might be important to tell me that ferns have sperm that swim??? I just had to find all this out on my own?

And, (apparently, & no one thought to bring this up either🙄) fern plants are only one form… they have this 'other form' (tiny, ephemeral, difficult to find in the wild) alternates generations-- Fern spores don't grow into ferns! (WHAT) they grow into 'gemetophytes' (WHAT) THEN you get a fern.

Feel like I've uncovered a massive scandal.

I'm so tired of the notes my foraging post only being about mushroom consumption. Yes. Mushrooms can be hazardous. Yes, they are more hazardous than plants (partly because their characters are more subtle and more easily confused!!). However, SO ARE PLANTS. I'm so tired of the fear mongering surrounding mushrooms in the foraging community while plants are treated as essentially harmless. You need to know what you are looking at! You need to be able to describe it! Or you WILL eventually hurt yourself or others! If you cannot reliably key out a species, you cannot reliably double check yourself.

I told myself I was going to write this weekend, but instead, i hyperfixated on grabbing references for what Vash's wings are actually like

I can write about fluttering feathers all I want, but my autism knows that's not Right

There are more scenes that I didn't get around to grabbing, but I realized that might be pointless, because his wings in episode 12 are probably a panicked defense action and will settle on a more solid form the more he uses them.

For now, they're rather inky-black, solid elongated structures throughout the mass, with small blobs(reminiscent of wild trailing jade) flowing from his back into the "wing" itself

🥺 the worst part is, it's probably made up of his plant sap, and it's so dark because it's contaminated/wounded from Kni forcing himself inside and accelerating Vash's root growth beyond anything reasonable.

honestly i think in general i need to do more research into plants because magic-based life would operate much more like plants than animals, even if they look closer to animals (most of the time)

That’s not a hand. It’s a paw. And that vein running down his forearm? Well it just hints at something else - if you follow my drift

[thereareeyesinsidethetrees]

xylem is such a fun word but i don’t see it used very often and i feel bad for it, so it’s going in the name list

xylem and phloem are the parts of plants that…i forgot what they do. they’re in the inside of the stem or something i think. they help transport water and such? maybe?

y’know my biology teacher was great but i don’t remember basically anything of what i was taught about plants because i was so stressed trying to figure out how the fuck photosynthesis works

[covenawhite66]

In the 1920s, scientists noted this increasing plant complexity in the fossil record but were not able to pinpoint the reason land plants adapted to drier climates.

How the early land plants were able to adapt to new habitats and move beyond their original moist, boggy environments. These plants were small, usually no more than a few centimeters tall, and were found near streams and ponds. Land plants are now more resistant to drought, allowing them to thrive in new, drier environments.

However, about 400 million years ago, they developed vascular systems that allowed them to extract water more efficiently from the soil and use it for photosynthesis, a change that had a significant impact on the Earth’s atmosphere and ecosystems.

Hydraulic failure as a primary driver of xylem network evolution in early vascular plants.

#1877 - Lunularia cruciata - Crescent-cup Liverwort

Spotted growing around the irrigation sprinklers in the gardens of the Melbourne Immigration Museum. The only species in the genus Lunularia and family Lunulariaceae. As with the spleenworts, the common name is derived from their shape and imagined usefulness against liver complaints (often themselves imagined).

A robust and hardy thallose liverwort, common in shady damp spots in gardens. It resembles the better-known Marchantia, but in this liverwort the gemma cups are crescent-shaped rather than circular (hence 'lunularia'). Gemma cups contain modified clumps of tissue - gemmae - that can be splashed out by raindrops to become new plants. Probably originally native to Europe, and around the Mediteraanean, where the sexual forms (cross-shaped, hence 'cruciata') are most common. In other parts of the world, it relies more on asexual reproduction via gemmae.

Liverworts are typically small, with individual plants less than 10 cm long, but some species can cover large patches of ground, or whatever substrate they prefer. Most of the 9000 estimated species are found in humid locations although there are aquatic, desert and Arctic species. Some species are minor weeds in shady greenhouses or gardens.

GUYS, OH MY GOODNESS YOU WON'T BELIEVE THIS!!!!!

My moss box has slime mold!!!!!!!!!!!! 🥺

P.S. does anyone know how to move slime mold off of glass? I want to give her a terrarium all to herself (:

However, there are now clear examples of single-cell C4 photosynthesis in a number of green algae, diatoms, and aquatic and land plants (Figure 8.12A). (...) Except in three terrestrial plants (see below), the distinctive Kranz anatomy increases the concentration of CO2 in bundle sheath cells to almost 10-fold higher than in the external atmosphere (Figure 8.12B and C). (...) Three plants that grow in Asia, Suaeda aralocaspica (formerly Borszczowia aralocaspica) and two Bienertia species, perform complete C4 photosynthesis within single chlorenchyma cells (see Figure 8.12A and C).
