Textbook Question

What is the benefit of having some of the cellular organelles enclosed by a membrane similar to the plasma membrane?

Verified step by step guidance

Understand the structure of the plasma membrane: The plasma membrane is a phospholipid bilayer with embedded proteins, which provides selective permeability, allowing certain substances to enter or exit the cell while maintaining internal conditions.

Recognize the role of membrane-bound organelles: Organelles like the nucleus, mitochondria, and endoplasmic reticulum are enclosed by membranes similar to the plasma membrane, which helps compartmentalize cellular functions.

Explain compartmentalization: Membrane-bound organelles create distinct environments within the cell, allowing specialized biochemical processes to occur without interference from other cellular activities.

Discuss selective transport: The membranes of organelles regulate the movement of molecules in and out, ensuring that only specific substances required for the organelle's function are allowed to pass through.

Highlight protection and efficiency: Membranes protect the organelle's contents from potentially harmful substances in the cytoplasm and increase the efficiency of cellular processes by concentrating enzymes and substrates in specific areas.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Membrane Structure

Cellular organelles are often enclosed by membranes that share a similar phospholipid bilayer structure to the plasma membrane. This structure allows for selective permeability, enabling the organelles to maintain distinct internal environments necessary for their specific functions, such as energy production or protein synthesis.

Compartmentalization

Compartmentalization refers to the division of cellular functions into distinct organelles, each surrounded by a membrane. This organization allows for specialized environments within the cell, facilitating efficient biochemical processes and preventing interference between incompatible reactions, thus enhancing overall cellular efficiency.

Endosymbiotic Theory

The endosymbiotic theory posits that certain organelles, like mitochondria and chloroplasts, originated from free-living prokaryotes that were engulfed by ancestral eukaryotic cells. This theory explains the double membrane structure of these organelles, as they retain their own membranes, which is crucial for their function in energy production and photosynthesis.
