Cell Tour
Support & Connections
Cytoskeleton
works with motor proteins
Microtubules (thick)
Tubulin dimers
Shape Cell, guides organelles, moves chromosomes
Centrosomes → Organizing Area
Cilia & Flagella → Movement
Microfilaments (thin)
Actin subunits
Maintains Shape
Plant Cells Wall
Made from cellulose
Protects Shape Prevents Water excess
Plasmodesmata → Channels between Cells
Extracellular Matrix [ECM] (Animals)
Glycoproteins: Collagens
ECM Binds to (Receptors)
Animal Cells Junctions
Tight Junctions → Prevents leaks
Desmosomes → Good Adhesion
Gap Junction → Cytoplasmic Channels
Endomembrane System
Smooth ER
No Ribosomes
Synthesis Lipids
Detoxifies poisons
Stores calcium ions
Rough ER
Secrets glycoproteins
Distributes transports vesicles
Build membranes
With ribosomes
Golgi Apparatus
Flattened Sacs = Cisternae
Modifies ER Products
Manufactures Macromolecules
Sorts and packages (ship and recieves)
Lysosomes
Membranous Sacs of Enzymes
Phagocytosis Takes and digests food
Autophagy → Recycles Organelles
Vacuoles
Central vacuole (plants)
Storees sap ion
important for cell growth
Genetics & Protein Synthesis
Nucleus
Contains most cell genes
Nuclear Envelope (lipid bilayer)
Nuclear spores regulate enter/exit
DNA organization
Chromosomes (DNA + Proteins = Chromatin
Nucleolus → rRNA synthesis site
Ribosomes
Made of rRNA & Proteins
No cytosol → Proteins for cell use
Functions to build proteins
Energy
Mitochondria (Power House of the Cell)
Area of cellular respiration → Makes ATP
Uses Oxygen
inner membrane → Folded into Cristae
Site of metabolic reactions
Chloroplasts (Light energy captured in plants)
Area of photosynthesis
Has chlorophyll
Structures: Thylakoids, Granum, Stroma
Peroxisomes
Single membrane
Enzymes form hydrogen peroxide H₂O₂
Breaks down fatty acids for fuel
Detoxify alcohol
glyoxysomes (fat to sugar in seeds)
