DownloadWhat is the primary function of the bacterial cell wall?
Omdraaien
The primary function of the bacterial cell wall is to provide structural support and protection, maintaining the shape of the cell and preventing it from bursting in hypotonic environments.
Describe the role of ribosomes in bacterial cells.
Omdraaien
Ribosomes in bacterial cells are responsible for protein synthesis, translating genetic information from mRNA to build proteins necessary for cell functions.
What distinguishes Gram-positive bacteria from Gram-negative bacteria?
Omdraaien
Gram-positive bacteria have a thick peptidoglycan layer in their cell wall, whereas Gram-negative bacteria have a thinner peptidoglycan layer and an outer membrane containing lipopolysaccharides.
How do antibiotics like penicillin affect bacterial cells?
Omdraaien
Antibiotics like penicillin target the bacterial cell wall by inhibiting the synthesis of peptidoglycan, weakening the cell wall and leading to cell lysis.
What is the significance of the bacterial capsule?
Omdraaien
The bacterial capsule provides protection against desiccation, phagocytosis, and helps in adherence to surfaces, contributing to the pathogenicity of bacteria.
Explain the process of binary fission in bacteria.
Omdraaien
Binary fission is the process by which bacterial cells reproduce. The cell duplicates its DNA, elongates, and divides into two genetically identical daughter cells.
What are the main differences between prokaryotic and eukaryotic cells?
Omdraaien
Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles such as mitochondria and the endoplasmic reticulum.
Define the term microbiome.
Omdraaien
The microbiome refers to the collection of microorganisms, including bacteria, viruses, fungi, and their genes, that inhabit a particular environment, such as the human body.
