Question

1. what process may have led to the evolution of eukaryotes from prokaryotes?
2. which type of cell is generally larger and more complex?
3. give two examples of eukaryotic organisms:
4. give two examples of prokaryotic organisms:

part 4: label the cells
a. prokaryotic cell
label these parts: cell wall, cell membrane, ribosome, flagellum, nucleoid, capsule, pili
sketch or label here:

Explanation:

1. Endosymbiosis is a widely - accepted theory suggesting that eukaryotes evolved from prokaryotes through a symbiotic relationship where one prokaryote was engulfed by another and became an organelle.
2. Eukaryotic cells are generally larger and more complex due to having membrane - bound organelles and a nucleus.
3. Animals (like a cat) and plants (like a rose) are examples of eukaryotic organisms.
4. Bacteria (such as E. coli) and archaea (like Methanococcus jannaschii) are prokaryotic organisms.

For labeling the prokaryotic cell: The cell wall is the outermost rigid layer, the cell membrane is just inside the cell wall, ribosomes are small structures for protein synthesis, the flagellum is a long, whip - like structure for movement, the nucleoid is the region containing the genetic material (not in a membrane - bound nucleus), the capsule is an outer - most slimy layer in some prokaryotes, and pili are hair - like appendages for attachment or conjugation.

Answer:

1. Endosymbiosis
2. Eukaryotic cell
3. Cat, Rose
4. E. coli, Methanococcus jannaschii

For prokaryotic cell labeling: Cell wall (outermost), Cell membrane (inside cell wall), Ribosome (small structures), Flagellum (long, whip - like), Nucleoid (genetic material region), Capsule (outer - most slimy in some), Pili (hair - like)
