What is the Difference Between Endosymbiosis and Invagination?

🆚 Go to Comparative Table 🆚

Endosymbiosis and invagination are two different theories that help explain the origin of eukaryotic cell organelles. Here are the key differences between the two:

  1. Definition: Endosymbiosis refers to the theory that describes the origin of mitochondria and chloroplasts inside eukaryotic cells from prokaryotic cells. Invagination, on the other hand, describes the origin of the nucleus and other membrane-bound organelles within the eukaryotic cells.
  2. Origin: Endosymbiosis occurs via the engulfment of prokaryotic cells by eukaryotic cells, while invagination occurs via the folding of the plasma membrane.
  3. Organelles: Endosymbiosis is related to the origin of mitochondria and chloroplasts, whereas invagination is related to the origin of the nucleus and other membrane-bound organelles.

In summary, both endosymbiosis and invagination are theories that help explain the origin of eukaryotic cell organelles, but they differ in their definitions, origins, and the specific organelles they are associated with. Endosymbiosis is related to the origin of mitochondria and chloroplasts via engulfment, while invagination is related to the origin of the nucleus and other membrane-bound organelles via folding of the plasma membrane.

    Here is a table comparing endosymbiosis and invagination:

    Feature Endosymbiosis Invagination
    Definition A theory that explains the origin of mitochondria and chloroplasts inside eukaryotic cells. A process that explains the origin of the nucleus and other membrane-bound organelles within the eukaryotic cell.
    Occurrence Occurs via engulfment. Occurs via folding of the plasma membrane.
    Organism Type Prokaryotic. Eukaryotic.
    Organelles Explains the origin of mitochondria and chloroplasts. Explains the origin of the nucleus and other membrane-bound organelles.
    Process Stage Formation of eukaryotic cells from a symbiotic relationship between prokaryotic cells. Occurrence of folding within prokaryotic cells to create membrane-bound organelles in eukaryotic cells.
    Evidence Similarity in size, DNA, and ribosomes between bacteria, mitochondria, and chloroplasts. Observations of membrane folding in prokaryotic cells.
