Explain centrioles and the endomembrane system.
Understand the Problem
The image provides information about centrioles and the endomembrane system. Centrioles are small cylindrical organelles involved in cell division, and the endomembrane system is a group of membranes and organelles that modify, package, and transport lipids and proteins in eukaryotic cells.
Answer
Centrioles organize microtubules; the endomembrane system modifies, packages, and transports lipids and proteins in eukaryotic cells.
Centrioles are cylindrical structures in animal cells that organize microtubules and play a role in cell division and cytoskeleton formation. The endomembrane system is a network of membranes and organelles (including the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, and plasma membrane) in eukaryotic cells responsible for modifying, packaging, and transporting lipids and proteins.

Centrioles are cylindrical structures in animal cells that organize microtubules and play a role in cell division and cytoskeleton formation. The endomembrane system is a network of membranes and organelles (including the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, vesicles, and plasma membrane) in eukaryotic cells responsible for modifying, packaging, and transporting lipids and proteins.
More Information
The endomembrane system does not include the membranes of mitochondria or chloroplasts.
Tips
It is important to understand that the endomembrane system is a dynamic and interconnected network, not just a collection of isolated organelles.
