Nucleus:
Structure - nuclear membrane, nuclear pores, chromatin, nucleolus
Function - Controls all activities in the cell, regulates transcription of genes, involved in directing protein synthesis.
Nucleolus:
Structure - proteins, RNA
Function - Formation of ribosomes.
Mitochondrion:
Structure - outer membrane, inner membrane, cristae, matrix
Function - Site of aerobic respiration. Provides large amounts of energy to form ATP.
Chloroplast:
Structure - outer membrane, inner membrane, thylakoid, granum (stacks of thylakoid), stroma
Function - Site of photosynthesis.
Vacuole / Vesicle:
Structure - membrane, cell sap
Function - Important in the storage of water, dissolved salts and sugar, maintaining shape and equilibrium.
Golgi Body:
Structure - flattened membrane discs, vesicles
Function - Involved in the packaging and processing of proteins made by the endoplasmic reticulum.
Endoplasmic Reticulum:
Structure - flattened membrane sacs
Function - Rough ER contains ribosomes. Site of protein and membrane synthesis. Smooth ER does not contain ribosomes. Involved in the synthesis of lipids and carbohydrate metabolism.
Ribosome:
Structure - large subunit, small subunit
Function - Site of protein synthesis, more specifically, site of translation.
Lysosome:
Structure - membrane, lipid layer, hydrolytic enzyme mixture
Function - Destroy foreign materials in the cell and recycle materials.
Cytoskeleton:
Structure - microtubules, microfilaments, actin filament
Function - Gives cells shape and structural support, involved in cell movement, holds organelles in place but can also move organelles, move chromosomes in cell division.
