Eukaryote Structure/ functions

Nucleus

Organelle that stores genetic information (DNA code).

Nucleolus

Assembly site for ribosomes.

Nuclear Envelope

Double membrane surrounding the nucleus.

Nuclear Pore

Passageway controlling molecular movement into and out of the nucleus.

Chromatin

Complex of DNA and protein.

Plasma Membrane

Controls movement of substances into and out of the cell.

Cytosol

Fluid portion of cytoplasm that serves as the site of metabolic pathways.

Cytoskeleton

Network of protein filaments providing cellular shape and aiding movement.

Ribosomes

Structures responsible for protein and polypeptide synthesis.

Rough ER

Membrane region involved in protein sorting and secretion.

Smooth ER

Membrane region involved in lipid synthesis and detoxification.

Golgi Apparatus

Organelle responsible for modification, sorting, and secretion of proteins and lipids.

Lysosome

Organelle involved in the degradation of macromolecules.

Peroxisome

Organelle involved in the degradation of hydrogen peroxide and other harmful molecules.

Mitochondrion

Site of ATP synthesis (energy production).

Centrosome

Region where microtubules grow; contains centrioles.

Cell Wall

Provides external rigid structure and support.

Central Vacuole

Handles storage and volume/turgor regulation.

Chloroplasts

Organelles that serve as the site of photosynthesis.
