How do bacteria reproduce?

Back

Bacteria primarily reproduce asexually through a process called binary fission.

Front

What is the difference between Gram-positive and Gram-negative bacteria?

Back

Gram-positive bacteria have a thick peptidoglycan layer and retain the crystal violet stain, while Gram-negative bacteria have a thin peptidoglycan layer and do not retain the stain.

Front

What is conjugation in bacteria?

Back

Conjugation is a process where bacteria transfer genetic material to one another through direct contact.
