cell replication and binary fission

Question 1

what is cell replication

Answer 1

cell replication is an asexual process. it is the content of 1 parent cell are copied to make 2 genetically identical daughter cells. both daughter cells have the same functionality as the cell that produced them.

Question 2

what are the reasons for cell to undergo cell replication?

Answer 2

growth
repair
procreation

Question 3

growth

Answer 3

growth- in order to grow, an organism must have more cells. cells can simply not just get bigger as they are limited in size

Question 4

repair

Answer 4

repair- old and damaged cells must be replaced so they do not cause disease

Question 5

procreation

Answer 5

procreation- in the case of bacteria, archaea, protozoa and even some multicellular eurkaryotics, the survival of the species depends on cell replication

Question 6

how do prokaryotes replicate

Answer 6

prokaryotes (archaea and bacteria) reproduce through a process of binary fission. this process is simplier and faster than asexual reproduction in eurkaryotic organisms.

Question 7

what are the steps of binary fission

Answer 7

• cell elongation
• dna replication
• septum formation
• 2 daugther cells

Question 8

what is binary fission

Answer 8

process of cell mutlicaption in bacteria and other unicellular organisms in which there is no formation of spindle fibres and no chromosomal condensation.

Question 9

cell elongation

Answer 9

the cell grows and elongates

Question 10

dna replication

Answer 10

replication of the circular dna chromosome, and the 2 circular chromosomes migrate to either ends of the cells

Question 11

septum formation

Answer 11

the cell membrane pinches in 2 and a septum (a new cell wall) forms along the middle of the cell

Question 12

2 daughter cells

Answer 12

the cell break into 2 identical daugther cells

Question 13

exponential growth

Answer 13

population growth that follows a J-shaped curve but cannot continue indefinitely.
