• The smallest unit of life
Molecules move from area of higher
concentration to lower
concentration
• Cells without a nucleus and membrane bound
organelles
• bacteria

Breaks things down and recycles them
Makes proteins
Makes energy
Photosynthesis
Processes and packages
Fluid of cell

Stores water and is large in the plant cell
• Water molecules moving across a membrane
from an area of higher water concentration to
lower water concentration
• Large (bulk) materials are leaving the cell via a
vesicle
• What are the 2 kinds of cell transport? What
is the difference between them?
• A structure inside a cell that performs a
specific function
• Some things can pass through but others can
not
• Molecules moving down their concentration
gradient with the help of a carrier or channel
protein
