1 Bio • Analyze how various organisms accomplish the following life functions through adaptations within particular environments (example: water or land) and that these adaptations have evolved to ensure survival and reproductive success.  Transport and Excretion – how different organisms get what they need to cells; how they move waste from cells to organs of excretion. Focus is on maintaining balance in pH, salt, and water. Include plants - vascular and nonvascular.  Respiration – how different organisms take in and release gases (carbon dioxide or oxygen, water vapor); cellular respiration  Nutrition – feeding adaptations and how organisms get nutrition (autotrophic and heterotrophic) and how they break down and absorb foods.  Reproduction, Growth and Development – sexual versus asexual, eggs, seeds, spores, placental, types of fertilization. • Analyze behavioral adaptations that help accomplish basic life functions such as suckling, taxes/taxis, migration, estivation, and hibernation, habituation, imprinting, classical conditioning (e.g. Pavlov’s dog–stimulus association), and trial and error learning

2 A. Transport in Organisms The term Transport describes all the process that move materials within an organism and into and out of cells.

3 Cells and Transport Materials that enter and leave a cell must pass through the plasma membrane. Diffusion, Osmosis, Active Support All organisms, both unicellular and multicellular, use these methods to transport materials into and out of their cells.

4 Diffusion Osmosis Active Transport

5 Diffusion Movement of Particles from an area of higher concentration to an area of lower concentration

6 Transport in Simple Organisms
Unicellular Organisms: Protistis Primarily by diffusion Cell exchanges materials with the environment based on concentrations of the material on either side of the plasma membrane by imageProtista includes all eukaryotic unicellular microorganisms
