4A: Binary Fission Flashcards
What is cell replication in prokaryotes and eukaryotes?
Prokaryotes: Binary Fission
Eukaryotes: Mitosis
What is cell replication important for?
Growth and Development
Maintenance and Repair
Reproduction
Do the cell sizes change as we grow bigger?
No, there are just more cells rather then them growing larger.
Cell replication is a form of:
- Exponential growth
- Linear growth.
Exponentially (doubles after each replication)
Process of binary fission?
D - DNA Replication. (the plasmids replicate independently)
E - Elongation (the cell elongates to prepare for more chromosomes and cell division).
S - Septum (a cell wall and membrane is formed in the middle to prepare for two new cells)
C - Cell division (the cell divides into two new genetically identical cells).
What is cytokinesis?
The division of the cytoplasm into two daughter cells
What is a septum?
The dividing wall created to prepare the cell for division.
What type of reproduction is binary fission and why?
Asexual reproduction, because there are no gametes involved.
What are the main purposes of cell replication? (Select all that apply)
I growth and development
II prokaryotic development
III prokaryotic reproduction
IV maintenance and repair
V prokaryotic repair
I, III, IV
When humans grow larger, their cells:
- Remain relatively constant in size.
- Become significantly larger.
- Become smaller.
Remain relatively constant in size
Prokaryotes replicate to:
- Increase their population
- Repair cells.
Increase their population
Plasmids are not evenly distributed between newly replicated cells because:
- There are not enough plasmids present to evenly distribute them.
- They replicate independently of the cell.
They replicate independently of the cell.
