Tour of the Cell

Nucleus

Structure: double membrane, pores for proteins/enzymes/RNA to flow in and out

Purpose: DNA storage, ribosome subunit assembly, RNA synthesis

Rough ER

Structure: Nuclear membrane connected, studded with ribosomes

Purpose: Proteins for membrane and secretaed protein synthesis, intracellular transportation

Smooth ER

Structure: No ribosomes, cisternae

Purpose: Lipid synthesis, detoxify, Ca storage

Golgi Apparatus

Structure: cisternae, vesicles

Purpose: Packaging, protein folding

Ribosomes

Structure: Bound or free

Purpose: RNA transcription into amino acids aka protein synthesis

Mitochondria

Structure: Own DNA, ribosomes, cristae (electrion trans chain), double membrane

Purpose: nutrients into ATP, endosymbiosis

Chloroplasts

Structure: only found in plants, stomata, (calvin), thylakoids (light rxns), own DNA+ribosomes

Purpose: photosynthesis, endosymbiosis

Lysosome

Structure: Fuses with food vacuole (phagocytosis), membrane studded with hydrolic enzymes (hydrolysis)

Purpose: digestion, apoptosis (cell suicide)

Vacuole (types+purposes)

central (plant): water, pressure (turgor)

Contractile: remove waste, osmoregulation

Food: food.
