And which eukaryotic cell is that? E nucleofilum is not an organisms but a microtubule?
The behavior of the pseudopodia are purely electrochemical responses to external conditions.
Wow, talk about an exemplar of Dunning-Kruger. Apparently you can't even manage to listen to what the video
you cited says.
From
your video:
01:13 The protozoan, Echinospherum nucleofilum is a model system for the investigation of microtubules.
01:21 This is a multinucleate organism, measuring about a hundred microns in diameter.
02:02 The Echinospherum feeds on other protozoa or on rotifers.
Echinospherum is a protozoa and a multinucleated organism. Note: the Echinospherum feeds, not its filum, which are essentially just the arms of the living organism Echinospherum.
So yes, Echinospherum are eukaryotes.
Since a filum is a "threadlike anatomical structure", it should be obvious to any intelligent person that Echinospherum nucleofilum are the threadlike anatomical structures of Echinospherum. The multinucleated eukaryote certainly isn't a "threadlike anatomical structure". All of the protrusions from the eukaryote are axopodia.
Again, as per your own video:
01:34 A large number of slender, rigid but elastic structures called axopodia project from the spherical body.
The axopodia are the filum, which contain microtubules enveloped in cytoplasm.

Chaos is a
genus of
amoebae, in the family
Amoebidae. The largest and best-known species, the so-called "giant amoeba" (
Chaos carolinense), can reach lengths of 5 mm, although most specimens fall between 1 and 3 mm.

So everything you've offered, so far, are already living organisms.
Via extracellular cue,

p.s. bacteria actually communicate via a chemical language,
as do non-living viruses.
This mode of chemical communication is called "quorum sensing" and
you do not have to be alive to react to chemical "messages".
Completely non sequitur to your ignorant claim that Echinospherum are neither eukaryotes nor alive.
OK, Eukaryotic cells are 'barely" alive, they evolved from the Prokaryotic cells that came before and are even closer
to non-living purely dynamic chemical patterns.
Anything more primitive than that gets into the bacteria and viruses and viruses are not considered alive . There is you missing link!!
Oh, now you admit that eukaryotes are alive, huh?
Yet no one has created a eukaryote. Hence your claims are ignorant bs. Trying to hedge your bets, with unscientific crap like "barely alive" and trying to conflate living bacteria with non-living viruses, is just demonstrating your intellectual dishonesty or ignorance.
You've proven your opinion to be woefully uneducated.
You see the little portrusions at the surface? In the E nucleofilum, these little chemical patterns are replaced by the pseodopodia. Alive or notalive, that is the question. And if we need to ask that it is evidence that we are observing an intermediate stage of abiogenesis, the emergence of life from non-living chemical patterns...
We don't need to ask because, as shown, your ignorance is the only reason you ask.
OK, your turn.
Is this chemical pattern of the E nucleofilum, which is a deadly invader of living organisms, alive or not alive?
If it is not alive but exhibits some characteristics of living oeganisms, then it MUST be the intermediate state from a purely non-living bio-chemical pattern into a living biological biome.
Again, you're just ignorant of the science you try to tout. Echinospherum is a multinucleated eukaryote (living organism) that has axopodia (filum) composed of microtubules.
I think you need to think this through. Seems you are confusing the
axopodia with
filum.

Sure, I'll try to explain it to you again, using another species as example.
Axopodia are filum. Go take an actual class on the subject.
Actinosphaerium nucleofilum is a living species of actinophryids.
The
actinophryids are an order of
heliozoa. They are the most common heliozoa in fresh water and can also be found in marine and soil habitats. Actinophryids are unicellular and roughly spherical in shape, with many axopodia that radiate outward from the cell body. Axopodia are a type of
pseudopodia that are supported by hundreds of microtubules arranged in a needle-like internal structure. These axopods adhere to passing prey and assist with cell movement, as well as playing a part in cell division and cell fusion.
...
This behavior has been documented in many species, including
Actinosphaerium nucleofilum,
Actinophrys sol, and
Raphidiophrys contractilis.
...
There are several genera included within this classification.
Actinophrys are smaller and have a single, central nucleus.
[9] Most have a cell body 40-50
micrometer in diameter with axopods around 100 μm in length, though this varies significantly.
Actinosphaerium are several times larger, from 200-1000 μm in diameter, with many nuclei
[9] and are found exclusively in fresh water.

I'll repeat that bit for your benefit:
Actinophryids are unicellular and roughly spherical in shape, with many axopodia that radiate outward from the cell body. Axopodia are a type of
pseudopodia that are supported by hundreds of microtubules arranged in a needle-like internal structure.
Sinking in yet? Actinophryids are unicellular, spherical organisms. They
have many axopodia. And those
axopodia are supported by microtubules.
Actinophryids nor Echinospherum are microtubules nor only filum. They are living organisms that you are stupidly trying to claim as evidence of life from the inanimate.
Try to actually learn something about the science you parrot without comprehension.
