Most of them. Lysosomes, endoplasmic reticulum, golgi apparatus, peroxisome, vacuoles all have single membranes. Nucleus has double membrane to make it less permeable, chloroplasts have membrane bound structures (thylakoid) inside its two membranes, and mitochondria have larger membrane that is folded within the outer membrane for added surface area.

What do bacteria and archaea have in common in terms of their cellular structure and genetic makeup?

Bacteria and archaea are both single-celled microorganisms that lack a nucleus and other membrane-bound organelles. They both have a simple cellular structure and their genetic makeup is composed of a single circular chromosome. Additionally, they both have a cell wall that provides structure and protection.


What do membrane proteins do in the context of cellular function and structure?

Membrane proteins play crucial roles in cellular function and structure by facilitating the transport of molecules across cell membranes, serving as receptors for signaling molecules, and helping to maintain the integrity and stability of the cell membrane.


Can be single- or multi-celled and have organization within their structure. Prokaryotes Eukaryotes?

Eukaryotes can be single-celled or multi-celled and have a defined internal organization with a nucleus and membrane-bound organelles. Prokaryotes are typically single-celled and lack a true nucleus or membrane-bound organelles in their structure.


What is the cellular structure that separates the cytoplasm from the external environment?

The plasma membrane is the cellular structure that separates the cytoplasm from the external environment. It is a phospholipid bilayer embedded with proteins that selectively controls the passage of molecules into and out of the cell.


What is the role of integral membrane proteins in cellular function?

Integral membrane proteins play a crucial role in cellular function by serving as gatekeepers for molecules entering and exiting the cell, facilitating cell communication, and helping maintain cell structure and shape.

Is the cell membrane a backturuim?

No, the cell membrane is not a bacterium. The cell membrane is a biological structure that surrounds the cell and regulates the movement of molecules in and out of the cell. Bacteria are single-celled microorganisms that can have a cell membrane as part of their structure.
