Transcript of Welcome to Cell City!

Plasma Cell Membrane - City Limits
Cytoskeleton - Buildings
Function of organelle:
Strengthens cell and helps maintain shape. It is the structural support
Made up of microtubules, actin and intermediate filaments.
No membrane
Nucleus - City Government
Function of organelle:
Controls cell activity. Assembles ribosomes into subunits
Contains hereditary material of cell
Has a double membrane
Nucleolus - Printing Company
Function of organelle:
Assembles ribosomes and transcribes rRNA
Made up of filament and protein
Has a single membrane
Smooth ER - Factories
Function of organelle:
Creates and stores lipids and steroids
Made up of enzymes for the synthesis of lipids and of sacs
Is a single membrane
Rough ER - Roads
Function of organelle:
Transports and stores materials. Packages proteins
Is made up of branching sacs like the Smooth ER but has ribosomes associated with it
Has a single membrane
Function of organelle:
Stores food, water, metabolic and toxic wastes.
Consists of many materials like pigments, oils, carbohydrates, etc
Is a single membrane that has transporters
Larger in plant cells
Centrioles - Neighborhoods
Function of organelle:
Separates chromosome pairs during mitosis. Helps the formation of spindle fibers
Made up of microtubules
Has no membrane
Welcome to Cell City!
Size: 10-30 µm
Function of organelle:
A semi-permeable membrane that regulates what goes in and out of cell
Is a phospholipid bilayer that contains transport and receptor proteins
Single membrane
Function of limits:
The border of a city
Is the area where people and objects leave or enter the city
Everything within the border is controlled by the city's government
Golgi Apparatus - Post Office
Mitochondria - Energy Plant
Chloroplasts - Solar Energy Plant
Vacuoles - Storage Facility
Lysosomes - Waste Management
Function of buildings:
Creates the shape of a city
Where the buildings are and where the city limits extend to
Function of government:
Controls all aspects of the city
Makes decisions that impact everything within city boundaries
Function of roads:
Allow objects and bodies to move throughout the city in an organized and efficient manner
Function of organelle:
Packages and exports proteins. Modifies protein made by cell
Consists of flattened cisternae
Is a single membrane with receptors
Function of post office:
Receives, packages, and ships objects and information to other parts of the city
Function of organelle:
Breaks down sugar to release energy. Makes energy through cellular respiration
Composed of enzymes that create oxidation-reduction reaction
Has a double membrane
Function of energy plant:
Generates energy to be used by the city from resources like coal, natural gas, or wind
Function of organelle:
Uses sun's energy to make food (glucose & ATP) through photosynthesis
Contains pigments and enzymes that create oxidation-reduction reactions
Has a double membrane
Function of solar energy plant:
Generates energy for the use of city from solar rays
Function of storage facility:
Can store food, water, and other products for the city's consumption in addition to waste
Function of organelle:
Breaks larger food molecules into smaller molecules. Digests and recycles old cell parts
Contains acid hydrolases
Is an organelle that has a single membrane that holds proton pumps
Function of waste management:
Disposal of the city's waste and recycles recyclable materials
Function of neighborhoods:
As neighborhoods spread and stretch the limits of the city, the city can separate into different cities.
Function of factories:
Produces products to be used by the city
Builds materials and stores within its walls for later shipment
Function of printing company:
Copies information and makes a replication of existing data
Copies, prints, and assembles information for the use of the city
