Eukaryote Cell Structures

Different cells have different organelles/number of organelles depending on their function.

Cell Membrane
Same functionality as prokaryote cell membrane.
More complicated than the cell membrane of prokaryotes.
Cell Wall
Provides protection and structure to the cells.
Only plants/fungi have cell walls.
No animals have cell walls - we have bones and don't need the extra support.

This allows us to target prokaryotic bacteria with antibiotics.
The antibiotics attack the cell wall of the pathogenic bacteria.

Cytoplasm
All cells have cytoplasm.
Cytoskeleton
Acts like a scaffold for the organelles.
Internal transport, intracellular movement, intracellular organization and support.

Endomembrane System

Cellular factory for where proteins and lipids are made.

Ribosomes Factory Workers
Protein synthesis (assembles amino acids)
Can be found free-floating in cytoplasm or on the Rough-Endoplasmic Reticulum.
Rough-Endoplasmic Reticulum Assembly Line Contains Ribosomes
Protein synthesis and modification for export.
Smooth-Endoplasmic Reticulum No Ribosomes
Handles lipid synthesis and detoxification.
This is not involved in protein synthesis.
Golgi Apparatus Processing Center
Modifies, packages, and sorts proteins from the ER into vesicles for delivery.
Vesicles Delivery Truck
Transports materials throughout the cell and to the cellular surface.

Protein Synthesis

DNA > RNA > Ribosomes > Rough-ER > Smooth-ER > Golgi Apparatus > Vesicles > Destination.

Prokaryotes

Prokaryotes don't have internal organelles and use ribosomes free-floating in the cytoplasm to build less-complex proteins.

Energy Production

Mitochondria Animals & Plants
Converts nutrients (consumed or found in soil) into ATP.
Chloroplasts Plants
Converts light energy into ATP.

Organelles

Maintenance and Storage

Lysosomes Cellular Janitors Animals
Contains digestive enzymes.
Breaks down waste, work-out organelles, foreign substances.
Plants have cell walls and have less cleanup to do.
Peroxisomes Detox Centers Animals & Plants
Detoxifies harmful substances.
Breaks down fatty-acids/lipids.
Convert hydrogen peroxide to water.
Vacuoles Storage & Support Animals & Plants
Used as small, temporary storage vesicles in animals.
Used for water storage and structural support in plants.

Motility Structures

Cilia
Tiny hair like structures on the outside of the cell used for moving external fluids.

Moving mucus in respiratory tract.

Flagella
Tail used for movement.

Sperm cell locomotion.

Microvilli
Provides increased surface area for increased absorption.

Small intestine cells - maximize nutrient absorption
