Transcript of Little Mito

Nuc, Flag, ER, Mito?
Chlora, Golgi, Ves, Lys?

Chloroplast- Found in higher plan cells. Contains Chlorophyll, giving the green color to plants.

Golgi Apparatus- Stack of membrane bound vesicles, package and transport.

Vesicle-a supramolecular assembly of lipid molecules, like a cell membrane.

Lysosome- Contain enzymes necessary for digestion.
The endosymbiotic hypothesis is mainly focusing on mitochondria and chloroplasts’ origin. These two
are prokaryotic cell “ate” smaller organelles which evolved into what they are today.

The autogenic hypothesis suggests that the origin of the eukaryotic cell is also the prokaryotic cell. This means that the prokaryotic cell regenerated by itself . This has then resulted to the similar organelle structure of the eukaryotic cell. It has also been said that the prokaryotic acquired a nucleus then which helped the formation of eukaryotic cells.
Autogenic hypothesis of the origin of the Eukaryotic cell
Little Mito
Evidence of the Autogenic hypothesis
Learning About Little Mito:
Nucleus- In charge of all organelles.

Flagella- the tail of a cell, assisting in movement.

Endoplasmic Reticulum- Head of distribution an storage also provide hormones.

Mitochondria- Provides energy to cells essential for their processes to continue.
Hypothesis is thought to be feasible because it is known today from scientific observation that transfer of DNA occurs between bacteria species, even if they are not closely related. Bacteria can take up DNA from their surroundings and have a limited ability to incorporate it into their own genome.
the endosymbiotic hypothesis is both mitochondria and chloroplast are arising from prior organelles and the nuclear genes provide some proteins that are very helpful to them both.

The autogenic and endosymbiotic hypotheses try to explain how the organelles of eukaryotic cells,
the cells of all organisms more advanced than bacteria, arose. The endosymbiotic hypothesis was first
proposed by woman scientist and is generally accepted nowadays as an explanation for how some
organelles and mitochondria arose in cells.
