The document summarizes key cellular organelles: the nucleus contains DNA which provides unique cell characteristics; the endoplasmic reticulum is a maze of membrane channels involved in protein transport; the Golgi apparatus packages macromolecules for transport; mitochondria generate energy for the cell; and ribosomes assemble proteins encoded by RNA. The document was written by Karthika V S for her natural science class at Emmanuel College with the course number 18114361007.

3. NUCLEUS
• In where DNA, which
responsible for
providing the cell with
its unique
characteristics , is
located. “BRAIN”

4. ENDOPLASMIC RETICULUM
• A three dimensional maze of
connecting and branching
channels made by
continuous membrane
within the cytoplasm of cells
• Rough ER
• Smooth ER

5. GOLGI APPARATUS
• Important for packing
macro molecules for
transport around the
cell. “PACKAGERS”

6. MITOCHONDRION
• Provide the energy a cell
needs “POWER
HOUSE”

7. RIBOSOME
• Serves as the site of
assembly far polypeptide
encoded by RNA
“PROTEIN FACTORY”
