CELL PARTS
ANIMAL CELLS
PLANT CELLS
ORGANELLE


A specialized subunit within a cell that has a specific function.
The name organelle comes from the idea that these structures are to cells what an organ is to the body.
CYTOPLASM



Both plant/animal
Clear, thick, jellylike material
Supports/protects cell organelles
NUCLEUS



Both plant/animal
Large, oval
Controls cell activities
NUCLEOLUS





Both plant/animal
The nucleolus is a knot of chromatin
Chromatin is DNA in its active form
Made of protein and nucleic acids
Site where ribosomes are made
NUCLEAR MEMBRANE




Both plant/animal
Surrounds nucleus
Selectively permeable
Controls movement of materials in/out of nucleus
CHROMOSOMES





Both plant/animal
An organized structure of DNA and protein
Single piece of coiled DNA containing many genes
Controls activities of the cell
Pass on traits/blueprint for life
ENDOPLASMIC RETICULUM




Both plant/animal
Network of tubes or membranes
Carries materials through cell
Internal delivery system
RIBOSOMES



Both plant/animal
Small bodies free or attached to E.R.
Produce proteins
MITOCHONDRIA




Both plant/animal
Bean-shaped with inner membranes
Breaks down sugar molecules into energy
ATP
VACUOLE




Plant – few/large
Animal – small
Fluid-filled sacs
Store food, water, waste (plants need to store large amounts of food)
CELL MEMBRANE









Both plant/animal
Plant – inside cell wall
Animal – outer layer; cholesterol
Selectively permeable
Support and protection
Controls movement of materials in/out of cell
Barrier between cell and its environment
Maintains homeostasis
AKA – plasma membrane
CELL WALL







Plant, not animal
Outer layer
Rigid, strong, stiff
Made of cellulose
Support (grow tall)
Protection
Allows H2O, O2, CO2 to pass into and out of cell
CHLOROPLASTS



Plant, not animal
Green, oval usually containing chlorophyll (green pigment)
Uses energy from sun to make food for the plant (photosynthesis)
LYSOSOMES





Plant – uncommon
Animal – common
Small, round, with a membrane
Breaks down larger food molecules into smaller molecules
Digests old cell parts
CENTRIOLES



Animal, not plant
The walls of each centriole are usually composed of nine triplets of microtubules (protein of the cytoskeleton).
Play a role in cell division
STRUCTURE & FUNCTION




Organelles are small structures within cells that perform dedicated functions.
As the name implies, you can think of organelles as small organs.
These organelles allow the cell to function properly.
The function of each organelle is directly related to its structure.
What does each of them have?
