SUMMARY

The discussion confirms the membrane structures of various cellular organelles. The nucleus, nuclear envelope, chloroplasts, and mitochondria are identified as having a double membrane, while the smooth and rough endoplasmic reticulum, Golgi body, central vacuole, lysosomes, and peroxisomes possess a single membrane. Ribosomes, cilia, and flagella are noted as having no membrane, as they are not separated from the cytoplasm. The distinction between cilia/flagella and the plasma membrane is clarified, emphasizing their encasement within the lipid bilayer.

PREREQUISITES
  • Cell biology fundamentals
  • Understanding of organelle structures
  • Knowledge of membrane types (single vs. double)
  • Familiarity with eukaryotic cell components
NEXT STEPS
  • Research the functions of organelles with double membranes, such as chloroplasts and mitochondria
  • Explore the role of ribosomes in protein synthesis
  • Study the structural differences between cilia and flagella
  • Examine the significance of the plasma membrane in cellular functions
USEFUL FOR

Students and professionals in cell biology, biochemistry, and related fields who seek to deepen their understanding of cellular organelles and their membrane structures.

Lysosomes - single Membrane
Chloroplasts - Double membrane
Mitochondria - Double membrane
Ribosomes -no membrane
Cilia-No membrane
Flagellum- No membrane
Am I right?

Looks good to me, though I'm not sure about cilia and flagella. Both are not separated from the cytoplasm by a membrane, but they are structures on the plasma membrane, which is a single membrane.

CIlia/ flagella are encased by the cell membrane (lipid bilayer).

And peroxisome is bound by single membrane,right?
