Organelle Plasma membrane

Function selective barrier that gives integrity to cell while allowing passage of O2, nutrients, wastes contains genetic material (DNA) site of 1st step in gene expression (transcription from specific genes)

+

Nucleus

+

+

Ribosomes

site of 2nd step in gene expression (translation of RNA to make proteins)

+

+

Endoplasmic reticulum

continuous with nuclear envelope synthesis of lipids and production of membrane, binds ribosomes synthesizing proteins destined for export or internal compartments

+

+

Golgi Mitochondria

Processing and packaging of proteins cellular respiration, conversion of energy to generate ATP

+ +

+ +

Chloroplast Lysosomes Central Vaculole

Photosynthesis digests engulfed food membrane-enclosed compartment that contains water used to help cell elongate

Cytoskeleton

provide shape, strength, movement of and within cells

Centriole Cell wall Cilia or flagella

separates chromosomes at division provides support for cell, organism movement of cells
