Nucleus

Largest organelle

Surrounded by nucleur envelope which contains pores

Pores allow mRNA to leave nucleus during protein synthesis

Controls activities of cell

DNA carries genetic code for making protein synthesis.

1 of 4

Nucleolus

Dense spherical structure found in the nucleus

Produces RNA and ribosomes needed for photosynthesis

2 of 4

Endoplasmic Reticulum

Series of flattened saces called cisternae

RER ( ROUGH ENDOPLASMIC RETICULUM)

CONTAINS RIBOSOMES

USED FOR PROTEIN TRANSPORT

SER (SMOOTH ENDOPLASMIC RETICULUM)

MAKES AND TRANSPORTS LIPIDS AND STEROID HORMONES

3 of 4

Ribosomes

Tiny organelles attached to the RER

Made up of two sub units

1 small sub unit nd 1 large sub unit

Ribosomes are involved in protein synthesis

They move along molecules of mRNA and read the nucleotide code to produce proteins

Ribosomes are made of RNA ( produced by the nucleolus and protein)
