Compare and Contrast Passive and Active Transport using a graphic organizer.
What are three examples of passive transport? Active Transport?
Compare and Contrast Endocytosis and Exocytosis.
If organisms fail to adjust and respond to changes in their environment, they may not be able to survive or thrive. This could lead to population decline or extinction.
Homeostasis is the process by which organisms maintain a stable internal environment despite external changes. It involves the regulation of various factors such as temperature, pH, and nutrient levels.
Cells control various factors with homeostasis, including water balance, ion concentration, pH levels, and temperature.
Selective permeability refers to the ability of a membrane to only allow certain substances to pass through while blocking others.
Passive Transport Active Transport
Requires no energy Requires energy (ATP)
Moves substances from high to low concentration Moves substances from low to high concentration
Includes diffusion, osmosis, and facilitated diffusion Includes ion pumps, exocytosis, and endocytosis
Endocytosis Exocytosis
Moves substances into the cell Moves substances out of the cell
Involves vesicle formation and fusion with the cell membrane Involves vesicle formation and fusion with the cell membrane
Examples include phagocytosis and pinocytosis Examples include secretion of hormones and neurotransmitters
