Organelles are components of microbes that allow them to complete certain processes. Organelles can be added and removed from microbes through the editor. There are currently 7 organelles in Thrive. Each individual organelle placed in the cell increases its health by 10 units.

Storage Organelles

Storage organelles increase the number of compounds that can be stored inside the microbe at any one time. If the number of compounds exceeds the storage capacity, excess compounds will be ejected.


  • Description: Vacuoles are the place in which compounds are stored for microbes to be used later. More vacuoles on a particular microbe means more compounds can be stored at one time. Each vacuole occupies one hex.
  • Capacity: 100 compounds
  • Size: 1 hex
  • Cost: 15 Mutation points


  • Description: Cytoplasm is the solvent medium in which chemical reactions in the cell take place, and works as an empty and cheap structural material for shaping the cell. Each tile of cytoplasm occupies one hex.
  • Capacity: 10 compounds
  • Size: 1 hex
  • Cost: 5 Mutation points

Process Organelles

Process organelles perform processes, which take some compounds as input and return different compounds as output.


  • Description: Mitochondria are organelles which function to produce ATP from glucose and oxygen. Without a mitochondrion a microbe cannot function properly and will quickly die. A mitochondrion occupies two hexes.
  • Process: Respiration (Glucose + 6 Oxygen → 6 CO2 + 36 ATP)
  • Size: 2 hexes
  • Cost: 20 Mutation points


  • Description: Chloroplasts are an organelle which turn CO2 (Carbon Dioxide) and sunlight into oxygen and glucose.
  • Unlocking: By swimming around in the environment, the player might find a green bubble (representing a cyanobacterium or similar photosynthesizing protist). Collecting this object will unlock the Chloroplast.
  • Process: Photosynthesis (6 CO2 → Glucose + 6 Oxygen)
  • Size: 3 hexes in a triangular shape
  • Cost: 20 Mutation points.

Movement Organelles

Movement organelles allow the microbe to move by applying a force, at the cost of some compounds. More movement organelles consume more compounds, but allow the microbe to turn and move more quickly.


  • Description: Flagella are the basic movement parts of microbes. They allow your microbe to move faster, but also take up more ATP for each consecutively added flagella. Direction in which flagellum propel the player's microbe forward is determined by where it is placed before it is officially bought in relation to the center.
  • Size: 1 hex
  • Cost: 25 Mutation points

Agent Organelles

Agent organelles are organelles that produce, store, and release agents, which are compounds that perform a useful process outside of the cell.

Toxin Vacuoles

  • Description: Toxin vacuoles are currently the only way to harm other microbes (as of version 0.2.4). If the E key is pressed the player will release a single OxyToxy from their microbe's toxin vacuole. If this agent comes in contact with another microbe it will sustain damage.
  • Unlocking: By swimming around in the environment, the player may find a clear bubble with a golden center. Collecting this object will unlock the Toxin Vacuole.
  • Process: OxyToxy Synthesis (3 Oxygen → OxyToxy NT)
  • Agent: OxyToxy NT
  • Size: 1 hex
  • Cost: 40 Mutation points

Nucleus Organelles

Nucleus organelles are the centre of the cell, and are responsible for containing the genetic information of the cell as well as producing proteins. Every microbe in Thrive has exactly one nucleus; additional nuclei can not be added or removed.


  • Description: The nucleus carries the genetic information of the cell. It also comes with two attached organelles, visible below it: the endoplasmic reticulum, which manufactures proteins, and the golgi apparatus, which packages proteins to send them to different places in the cell.
  • Processes: Amino Acid Synthesis (Glucose + Ammonia → CO2 + 2 ATP + Amino Acids); Reproductase Synthesis (6 Amino Acids + 6 Glucose + 6 Oxygen + 6 ATP → 5 Reproductase)
  • Size: 10 hexes
