3.4 Diffusion and Osmosis
KEY CONCEPT Materials move across membranes
because of concentration differences.
3.4 Diffusion and Osmosis
Passive transport - does not require energy input from
a cell.
• Molecules can move across the cell membrane
through passive transport.
• There are two types of
passive transport.
• diffusion
• osmosis
3.4 Diffusion and Osmosis
• Osmosis - is the diffusion of water molecules across a
semipermeable membrane.
• Diffusion – movement of a substance from where there is a
large amount to where there is a small amount
3.4 Diffusion and Osmosis
• There are three types of solutions.
•
isotonic – concentrations are equal
hypertonic – solution has more solutes than a cell, cell
shrivels and dies
• Hypotonic – solution has fewer solutes than a cell,
cell expands and may burst
•
hypertonic
hypotonic
3.4 Diffusion and Osmosis
Some molecules can only diffuse through transport
proteins.
• Some molecules cannot easily diffuse across the cell
membrane.
• Facilitated diffusion diffusion through transport
proteins.
3.5
Active Transport, Endocytosis, and Exocytosis
Active transport - Cells use energy to transport
materials that cannot diffuse across a membrane.
3.5
Active Transport, Endocytosis, and Exocytosis
A cell can import and export large materials or large
amounts of material in vesicles during the
processes of endocytosis and exocytosis.
• Cells use energy to transport material in vesicles.
• Exocytosis - the process of
expelling material from inside
the cell to outside the cell.
• Endocytosis - the process of
taking material into the cell
• Phagocytosis - a type of
endocytosis

SYSTEMS
root system
• Tissues - groups of cells that
perform a similar function.
• Organs - groups of tissues that
perform a specific or related
function.
• Organ systems - groups of
organs that carry out similar
functions.
