Lesson objectives
• Know the structure of an animal and plant cell
• Label and explain the function of structures within a cell
Animal cell (cheek cell)

Structure
Function
Cell
Membrane
Controls the entry and exit of substances
Cell Wall
(cellulose)
Structural support for the cell
Cytoplasm
Site of most chemical reactions
Nucleus
Contains chromosomes which carry genetic
information and control the activities of the cell
Mitochondria Site of aerobic respiration
Ribosome
Site of protein synthesis (where proteins are
made)
Vacuole
Contains cell sap (sugary water solution). A
swollen vacuole pushes the rest of the cell
contents against the cell wall, making the cell
firm
