Document Summary
**prof shows us video of binary fission of s. pyogenes. It is important to note that these long chains don"t just grow from the outside, they are getting longer due to the division of every cell in the chain (not just the ones on the ends) **prof shows us video of binary fission of s. aureus. These cells grow in clusters and therefore can divide in all planes (or very many different planes) We see two colonies merging no longer a pure culture because two cell lines have come together. This is why we like to use more isolated colonies when growing cells in culture (like, the ones we pick should be isolated) We see that the plane is nicely seen. The mother cell will not increase in size. Once the budding cell is the same size as the mother cell, it will separate.
