Study Notes
Cellular Organelles
- Ribosomal RNA (rRNA) synthesis occurs in the nucleolus.
Endomembrane System
- The main function of the endomembrane system is to modulate cellular transport and storage.
Cell Control Center
- The nucleus is the control center of the cell.
Nucleus-Cytoplasm Interaction
- The nuclear envelope is the structure that controls the passage of materials between the nucleus and cytoplasm.
Endoplasmic Reticulum
- The endoplasmic reticulum is responsible for protein synthesis, folding, and transport.
Nucleolus
- The nucleolus is the site of ribosomal RNA (rRNA) synthesis and ribosome assembly.
Nuclear Pores
- Nuclear pores regulate the passage of molecules between the nucleus and cytoplasm.
Nucleus Structure
- The nucleus consists of a double membrane separated by perinuclear space.
Nucleolus Characteristics
- The nucleolus is rich in RNA and basic proteins and has no membrane.
Cellular Transport
- The endomembrane system modulates cellular transport and storage.
Nucleolus Function
- The nucleolus is responsible for ribosomal RNA (rRNA) synthesis.
Cellular Structure
- The nucleus consists of a double membrane separated by perinuclear space.
