Cell Cycle Mitosis Binary Fission

Purpose of cell replication

• Restoring cytoplasm in a newly divided cell

• growth and development

• Repiar and maintenance

• Create new energy sources

Cell replication in ​ (a)   is called ​ (b)   . This form of cell replication​ is an ​ (c)   process which means it doubles after each cycle of binary fission. Binary fission happens every 20 minutes in prokaryotes, which is considered ​ (d)   .

• prokaryotes
• exponential
• fast
• slow
• binary fission
• replication
• DNA
• plasmid
• nucleus
• mitosis

Reorder the stages of binary fission in the correct order, use your diagram below. (Use the diagram as a hint, it does not necessarily correspond with the stage numbers)

• DNA is moved to seperate poles of the cell

• Two new identical daughter cells are created

• DNA molecule replicates intro two circular strands

• New cell wall and plasma membrane is formed

• Cell grows twice its original size

.​ (a)   is a type of cell replication seen in ​ (b)   . This form of cell replication contains several DISTINCT phases where the DNA is ​ (c)   and divided. The end result of this form of cell replication is two ​ (d)   ​ (e)   daughter cells.

• mitosis
• eukaryotes
• duplicated
• genetically
• identical
• meiosis
• binary fission
• unique
• diverse
• multiple

Match the following

• Cell not undergoing replication

• Interphase

• Chromatids separate and move to opposite poles

• Anaphase

• Nucleus breaks down, chromosome condense

• Telophase

• Chromosomes reach the poles and the nuclear envelope reforms

• Metaphase

• Chromosomes align at the cell's equator

• Prophase

(c) Binary fission AND Mitosis

• nucleus breaks down during replication

• Contains multiple stages, pro, meta, ana, telophase

• Form of cell replication

• Used by Prokaryotes

• 2 hours to fully replicate

• Used by Eukaryotes

• 20 minutes to fully replicate

• Creates two daughter cells

• Plasmids are used to help generate some genetic diversity

• Daughters cells are identical
