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 hypotonic hypertonic
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
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. SYSTEMS leaf shoot system stem vascular tissue CELL TISSUE ORGAN root system lateral roots primary root
