  1. Asexual reproduction By your good friend: Addison

  2. Cell

  3. Cell division • When cells reproduce, they don’t do so the same way we do, but one cell will simply split into two. • This falls into the category of Asexual reproduction.

  4. The number 2. • Two types of cells: Prokaryotes and Eukaryotes. • Prokaryotes are simpler than Eukaryotes since they lack most organelles that Eukaryotes have.

  5. Prokaryotic fun facts • They don’t.. Usually reproduce sexually, they’re weird. • They usually reproduce using binary fission. • Since a Prokaryotic cell is lacking most organelles and even a nucleus, it really just has a long strand of DNA floating around and splitting is pretty simple.

  6. Prokaryotic reproduction • It starts with the really long DNA strand copying itself, making TWO DNA strands. Crazy, right? • After this, the two strands migrate towards opposite ends of the cell and start pushing outward. • The outer membrane pinches in towards the middle and then the former one cell becomes two daughter cells.

  7. See?

  8. Now, what you’ve all been waiting for…

  9. Eukaryotic cells!! • When Eukaryotic cells reproduce, it’s an ongoing thing, called Mitosis, but the splitting process has been categorized into four major phases Along with a really long phase that happens before any of that, called Interphase). • These phases are: • Prophase • Metaphase • Anaphase • Telophase

  10. Interphase • A cell spends 90% of its “cell cycle” in interphase. • The cell cycle is about a 24-hour process that a cell goes through, well, a cycle. • Interphase doesn’t really have anything specific the cell is doing, it’s basically just getting ready for Mitosis, which is (you do the math) about 10% of the cell cycle. • At the end of Interphase, DNA starts to replicate.

  11. Prophase/Prometaphase • Sister chromatids slowly condense to form chromosomes in the the center of the cell. • The nuclear envelope (holding DNA in) disintegrates.

  12. Metaphase • The chromosomes all line up along the center of the cell.

  13. Anaphase • Sister chromatids are pulled apart by the spindle fibers. • Chromatids become individual chromosomes. • At the end of Anaphase, each side has an equal amount of chromosomes.

  14. Telophase • Chromosomes are pulled to where they’ll be put into nuclei. • Chromosomes unwind and spread out. • A nucleus forms on each side.

  15. Cytokinesis • Membrane in the middle of the cell pinches inward. • The membrane cuts the two cells in half, creating two daughter cells.
