Organelles currently in the game:
-Structural Organelles: Cytoplasm (the most basic part of a cell. provides structure to the cell. converts a tiny bit of glucose to ATP and stores a small handful of compounds).
-Prokaryotic Structures: Metabolosomes (respires oxygen), Thylakoid (called chromatophores in the current version, does photosynthesis), Chemosynthisizing Proteins (does chemosynthesis, which basically means now you can eat up some tasty hydrogen sulfide), Rusticyanin (does iron respiration, an alternative to fermentation), Nitrogenase (does nitrogen fixation, which gives you ammonia. helps a lot with reproduction).
-External Organelles: Flagellum (that “tail” thing. provides quicker movement).
-Internal Organelles: Nucleic Core (called Nucleus in the current version. the mark of a eukaryote. extremely costly), Mitochondria (eukaryotic successor to the metabolosomes, way more efficient. the powerhouse of the cell), Chloroplast (more efficient version of thylakoids), Thermoplast* (does thermosynthesis, global warming won’t be a problem for you), Chemoplast*(the natural successor to the chemo proteins), Nitrogen Fixing Plastid/Nitroplast* (pretty self explanatory), Vacuole (the storage facility of the cell), Toxin Vacuole (makes and stores the oxytoxy NT, basically a weapon).
*Note: those plastids actually don’t exist in real life but in theory can.
Listed in the editor but not implemented are the predatory pilus (used to stab your fellow cells), cilia (provides more flexible movement than the flagellum but doesn’t make you as fast in one direction), Bioluminescent Vacuole (when light is implemented, will help you see in dark places. also makes your cell shiny).
I’m pretty sure there will also be thermosynthesizing proteins and ferroplasts added eventually. There are many more organelles to come, the world of cells is surprisingly diverse.
