The idea of the relationship between nuclear grade and cell size, and the evolution of film-like organelle

When I add nucleus to my cell, I feel puzzled. It’s so expensive that I can’t add other organelle. It’s so large that my cell expands to about twice its original size.
We need a transition plan between eukaryotes and prokaryotes. It can consult Gemmata obscuriglobus. It has a original Nucleus. And it has endocytosis ability, which most prokaryotes don’t have.

It also can consult Myojin parakaryote.

One idea is to provide the nucleus with a certain Osmolation Cost, while also providing a reduction in Osmolation Cost ratio like membrane type. It will encourage large cells to evolve nucleus and inhibit small cells.

Myojin parakaryote, has a large nucleoid structure surrounded by a single-layer nuclear membrane without nuclear pore.


Yeah, i suppose its meant to be that way. In order to have a nucleus, i’d reccomend having like 30-40 extra atp to spare in your cell before adding it.
but i like your idea :slight_smile:

I have a idea about nucleu evolution.
1.Free DNA [1]

2.Circular DNA(nucleoid) [3]

3.Original Nucleus [7]

4.Nucleus [10]

Although the genetic material of most bacteria is composed of a circular DNA and multiple plasmids, some bacteria have linear DNA instead of circular DNA, like Burkholderia cepacia, which has 3 linear DNA.

One view is that monolayer organelle come from the invagination of cell membrane folding, and bilayer organelle come from endosymbiosis.
With the advancement of observation technology, humans have discovered film-like organelle in prokaryotes too. Such as
photosynthetic membrane(photoreaction,
May prototype of thylakoid?),
vacuole(Storage and osmotic regulation) ,
Gas vesicle(Regulating cell specific gravity),
magnetosome(magnetotactic bacteria),
anammoxosome( Candidatus Scalindua),
Metabolosomes(Heterotrophic metabolism) and so on.
The special one is the mesosoma, which is a special invagination structure of the cell membrane, also called chondroid, the sites of aerobic respiration.

carboxysome(Carbon sequestration and poison production),[Membraneless organelles]

The idea of symbiosis to unlock organelle:
Mitochondrion: Engulf cells containing mesosomes.
Chloroplast: Engulf cells containing photosynthetic membrane and carboxysome .

An idea to associate membrane level with cell structure:
1.Free DNA: Membraneless organelle, protein, mesosoma;
2.Circular DNA(nucleoid): Unlock film-like organelle, allowing engulf block of nutrition;
3.Original Nucleus: Allowing engulf cell, internal symbiosis but limiting the kind of organelle obtained by endosymbiosis;
4.Nucleus: Unlimited kind of organelle obtained by endosymbiosis.

An obvious situation is that the cell size inside the game is not very realistic. For example, mitochondria and Escherichia coli are similar in size, but the mitochondria in the game are only 2 hexes, and the creatures of 2hexes are basically invisible in the game (10hexes are directly displayed in an automatic evo).

One idea is that for different levels of nuclei, the actual length and volume corresponding to each hex are different. For each hex:

Free DNA: 0.05µm(length) 0.25(size)
Circular DNA: 0.1µm(length) 1(size)
Original Nucleus: 0.2µm(length) 4(size)
Nucleus: 0.4µm(length) 16(size)
Free DNA,Circular DNA: 0.1µm(length) 1(size)
Original Nucleus: 0.2µm(length) 4(size)
Nucleus: 0.4µm(length) 16(size)

The possible problem is to amplify the efficiency of each stage’s structure.
Does the current game seem to directly amplify eukaryotes? At the fossil interface, there is a Base Hex Size that is different from Size, which seems to reflect the visual size of the cell. Which is the basis for phagocytosis, Base Hex Size or Size?

Is it feasible to limit the number and kinds of organelle by nuclear level? Additional expansion can be achieved by plasmids or small nuclears. It promotes species specialization, or upgrading nuclear, or turning to Multicellular organism.
Perhaps we need genetic complexity. It can also serve as a condition for nuclear upgrading. Not necessarily an absolute limit, it can be a penalty when overstepping.
