OrganellesBack ground: Eukaryotic cells have specialized structures that perform specific functions.

Essential Question: What are the roles of ribosomes, endoplasmic reticulum and the golgiapparatus in regards to proteins?

(Using color, Circle the information that explains the roles)

Vocabulary: Highlight or Underline important terms

Remember to show a Key

I. OrganellesA. Special structures in Eukaryotic cells

B. Perform necessary functions of the cell

C. 8 main kinds

1. Ribosome

a. used too make proteins

b. made of RNA and protein

c. Found free in cytoplasm or on ER

2. Endoplasmic Reticulum

a. the membrane system of inter- connected channels

b. transports proteins in the cell

c. Two Kinds

1. Rough ER ( ribosomes attached)

2. Smooth ER

3. Golgi Apparatus

a. takes in the proteins that are going to be exported from the cell

b. modifies, packages and transports proteins to the cell membrane

OrganellesStandard 1e: Students know the role of the endoplasmic reticulum and Golgi Apparatus in the secretion of proteins

OVERVIEW

Ribosomes

makes the proteins

ER

transports the proteins

Golgi Apparatus

packages & distributes the proteins
