Why are antibiotics ineffective against fungal infections?
Press to flip
Antibiotics target bacterial structures and functions, but fungal cells are more similar to animal cells, requiring antifungal treatments.
What components are universally present in both prokaryotic and eukaryotic cells?
DNA, ribosomes, cytoplasm, and cell membrane.
How are ribosomes involved in both prokaryotic and eukaryotic cells?
Ribosomes are responsible for protein synthesis in both prokaryotic and eukaryotic cells.
How does the presence of membrane-bound organelles enhance eukaryotic cell function?
Membrane-bound organelles compartmentalize cellular processes, increasing efficiency and complexity in eukaryotic cells.
In what domain would you classify organisms with multicellular structures and membrane-bound organelles?
Eukarya, which includes protists, plants, animals, and fungi.
What are some examples of membrane-bound organelles specific to eukaryotic cells?
Examples include mitochondria, chloroplasts (in plants), endoplasmic reticulum, and Golgi apparatus.
What is a common misconception about ringworm and what actually causes it?
Ringworm is not caused by a worm but a fungus.
In what ways do prokaryotic and eukaryotic cells manage genetic material differently?
Prokaryotic cells have free-floating DNA, while eukaryotic cells contain DNA within a nucleus.
What is the main structural component controlling entry and exit in all cells?
The cell membrane is responsible for regulating what enters and exits the cell.
What role do cell walls play in eukaryotic cells, and how does this differ among organism groups?
Plant and fungal eukaryotic cells have cell walls, while animal cells do not.
Why is it important to distinguish between prokaryotic and eukaryotic cells in treating infections?
Identifying the cell type is crucial for selecting appropriate treatments, such as antibiotics for bacterial infections and antifungals for fungal infections.
How does the complexity of prokaryotic and eukaryotic cells differ?
Prokaryotic cells have a simpler structure and lack membrane-bound organelles, while eukaryotic cells have a nucleus and complex organelles.
What is the significance of a nucleus in eukaryotic cells?
The nucleus houses the cell's DNA and is a defining feature that distinguishes eukaryotic cells from prokaryotic cells.
What distinguishes the domains Bacteria and Archaea from Eukarya in terms of cell structure?
Bacteria and Archaea are composed of prokaryotic cells which lack a nucleus and membrane-bound organelles, unlike eukaryotic cells found in the domain Eukarya.
How does understanding cell type contribute to our comprehension of biological diversity?
It helps explain the vast differences and complexity among living organisms by showcasing structural and functional variations.
