Homework Answers
- Endosymbiosis is the process where one cell uptakes another and retains the uptaken cell and both live together .
- chloroplasts and mitochondria are the organels that support the notion of endosymbiosis.
- mitochondria have thought to be developed from rickettsias through endosymbiosis and chloroplast from cyanobacteria.
- Oldest fossil Funisia dorothea a tube like creatures was found by paleontologists in 2005 to engage in sexual reproduction. they release floting eggs and sperm to produce mass births of larval offsprings.
- sexual reproduction is important for the living organisms to survive.genetic material of the two individuals combine to produce genetically diverse offspring that differ from parents.ie..new combinations of genes r produced every generation

4. Development of organelles Aa Aa 3 Modern eukaryotic cells are very complex and have many features that allow them to function efficiently. These complexities took a very, very long time to evolve and likely progressed as a series of small improvements that were naturally selected. For example, modern eukaryotic cells have internal membranes surrounding their organelles and the nucleus. This arrangement likely arose when the cellular membranes of some ancient bacterial cells accidentally folded to become internal membranes. Which...
