Animal Cell
-
Structures
Nucleus
-
-
Nuclear Pores
Allows transports of proteins, RNA, carbohydrates, lipids, and communication
-
-
-
-
-
Vacuole
Provides support, storage, waste disposal, protection, and growth
-
-
Cytoskeleton
Intermediate Filament
Function:
- Maintains cell shape (resists stretching)
- anchors nuclear envelope
- supports cell-to-cell cohesion
- forms nuclear lamia
-
Structure
Fibrous proteins that supercoil like rope
-
Microtubule
Function:
- Maintains cell shape
- Cell mobility via Flagella & Cilia
- Cell division (chromosome movement)
- Organelle movement
Motor Protein
Cytoplasmic dynein: (backwards movement towards minus end)
- Positioning of large organelles
- Cargo transportation (vesicles, lysosomes, peroxisomes)
- role in cell division
Kinesin: (anteretrograde movement towards plus end)
- similar to cytoplasmic dynein except in other direction
Axonemal dynein: (backwards sliding towards minus end)
- Cilia and flagella movement
Structure
-
Hollow cylinders
- grow from microtubule organizing center (MTOC)
- MTOC = basal bodies and centrosome
- positive end is away from MTOC
- unidirectional polymerization from (-) to (+) end
Microfilament
Function:
- Maintains cell shape
- Makes changes in cell shape
- muscle contraction
- cell movement via pseudopods
Motor Protein:
- myosin (walks toward + end of filament)
Structure
Two intertwined actin polymers
- Bidirectional polymerization (+ & - )
- 7 nm
-
Lysosome: digests food by merging with food vesicles
- Carries digestive enzymes

Chloroplast
Three layers (Inner & outer, Thylakoids)
-
-
-
-
Cell Wall
Provides structure, and protection
-
-
-
Bacteria Cell
Structures
-
Capsule:
Protects from engulfment, and helps spread itself
Cell wall:
Provide tensile strength, and protection from infection
-
Cytoplasm:
Where cell growth, metabolism, and replication happen
-
Nucleoid:
DNA spaghetti, also contains RNA, proteins, and enzymes
Ribosomes
Only has free floating ribosomes
- Uses amino acids to make protein
