This document summarizes different types of asexual and sexual reproduction in bacteria. The main types of asexual reproduction discussed are budding, fragmentation, and binary fission. Binary fission involves the bacterial DNA replicating and the cell membrane dividing the original cell into two identical daughter cells. Sexual reproduction in bacteria can occur through conjugation, transformation, or transduction, which involves the transfer of genes between bacteria through direct contact, uptake of extracellular DNA, or bacteriophage transmission, respectively.

3. Type of Asexual
reproduction in
bacteria :
Budding
Fragmentation
Binary Fission

4. Budding:In
this case
small bud
farmation from
a parental cell.
And daughter
cell , finally
gets
separated
from the
parent cell.

5. FRAGMENTATION: This is a
form of reproduction where a
new organism grows from a
fragment of parent cell.
Each fragment develops into in
a fully grown individual.

7.  Binary Fission – It is division of a single cell into
two or more cells,and the regeneration of those
cells into separate entities resembling the
original cell.

8. single DNA molecule replicates and both
copies attach to the cell membrane.
The cell membrane begins to grow
between the two DNA molecules

9. the cell membrane begins to pinch
inward;
cell wall then forms between the
two DNA molecules dividing the
original cell into two
identical daughter cell

10. BINARY FISSION

11. SEXUALREPRODUCTION
 Many plasmids can insert into the DNA of the nucleus, and
detach from it. In doing so, the plasmid may leave part of
the plasmid DNA behind, and take some of the nuclear
DNA with it.

12. SEXUALREPRODUCTION
 plasmids can transfer from cell to cell. The cells need not be
of the same bacterial 'species'.

13. SEXUAL REPRODUCTION:
 Conjugation
 Transformation
 Transduction

14. CONJUGATION
 one bacterium connects itself to another
through a protein tube structure called a
PILUS. Genes are transferred from one
bacterium to the other through this tube.

16. TRANSFORMATION
 The bacterium binds the DNA and transports it
across the bacterial cell membrane. The new DNA
is then incorporated into the bacterial cell's DNA.

18. TRANSDUCTION
 involves the exchanging of bacterial DNA
through bacteriophages.

20. BACTERIOPHAGES
viruses that infect bacteria. There are two types of
transduction: generalized and specialized
transduction.
