Liquid Portion of cell outside the Nucleus All cells have cytoplasm Allows for movement of materials within the
cell itself

Contains nearly all the cells DNA Surrounded by Nuclear Envelope
◦ Contains pores to let materials in and out Chromatin: DNA unwound and bound to
protein◦ Condenses to divide=Chromosomes
Nucleolus: Small dense region for assembly of ribosomes

Convert chemical energy in food to useable energy for the cell
Outer and inner membrane Inherited from mother Generates ATP (energy) for the cell

Composed of microtubules Aids in cell division by dividing and
organizing chromosomes ONLY found in animal cells ONLY active during cell division

Capture energy from sunlight and convert CO2 to SUGARS (Photosynthesis)
Found in Plants and some Protists

Site of synthesizing materials◦ Proteins (Rough)◦ Lipids (Smooth)◦ Other materials and detox
Smooth ER◦ No ribosomes present
Rough ER◦ Ribosomes present on surface

Made of RNA (no membrane) Produce proteins by following coded
instructions from the Nucleus Found in ALL CELLS

Breaking down of molecules Contain ENZYMES
◦ Remember the chicken liver lab? Can also break down old, unusable
organelles

Storage◦ H2O, salts, protein and carbohydrates
Important for plant cells◦ Why would this be?
Support structure of plant

Support of the cell Microfilaments
◦ Thread like structure, made of the protein Actin◦ Form extensive networks◦ Help the cell move
Microtubules◦ Hollow structures, made of protein Tubulins◦ Maintaining cell shape◦ Centrioles: located near cell nucleus, help
organize cell division
