Download Organelles of the Cell Part I

Organelles of the Cell Part I
Three Sections of the Cell
cytoplasm
• All cells take in food,
rid waste, reproduce
• 3 main sections
• 1) Plasma membrane
• 2) Nucleus
• 3) Cytoplasm
Cytoplasm
• Jelly-like
material inside
of the cell
• Most organelles
float within

•
Aka: Cell Membrane
Composition: Bilayer of lipids & proteins
glucose
Job: Allow materials to enter/exit
Semi-Permeable: only specific materials may
enter and exit through pores & protein channels
nucleolus
nucleolus
• Job: Controls cell
activity
• Inside:
1) Chromatin
• long strands of
DNA
• holds info to
make proteins
2) Nucleolus: makes
ribosomes
Endoplasmic Reticulum
nucleolus
chromatin
• Rough ER
nuclear
envelope
– Receives ribosomes from the
nucleus
– Job: Tunnel system that transports
protein making ribosomes
Endoplasmic Reticulum
• Rough ER
– Receives ribosomes from the
nucleus
– Job: Tunnel system that transports
protein making ribosomes
• Smooth ER:
– makes fats &
breaks down
toxins (no
ribosomes)

• Transported by the rough ER
• Job: make proteins
Golgi Body
• Job: Modifies, sorts, & packages proteins
• Proteins released inside a protective vesicle
