Chapter 10: Transport Systems in Organisms
Understand the Problem
The document seems to be a study guide or notes on transport systems in organisms, covering topics such as diffusion, osmosis, and the components of blood, including xylem and phloem functions in plants.
Answer
Multicellular organisms use circulatory and vascular systems; unicellular organisms rely on diffusion and osmosis.
The primary transport mechanisms in multicellular organisms include the circulatory system for animals and vascular tissues (xylem and phloem) for plants. Unicellular organisms predominantly rely on diffusion and osmosis for transport.
Answer for screen readers
The primary transport mechanisms in multicellular organisms include the circulatory system for animals and vascular tissues (xylem and phloem) for plants. Unicellular organisms predominantly rely on diffusion and osmosis for transport.
More Information
Transport systems are essential for moving nutrients, gases, and wastes efficiently throughout an organism. In plants, xylem and phloem play a crucial role. In animals, blood and its components (plasma, red and white blood cells, and platelets) ensure efficient transport and immune response.
Tips
A common mistake is confusing the role of xylem and phloem or misunderstanding diffusion and osmosis. Remember, xylem transports water and minerals unidirectionally, whereas phloem transports food bidirectionally.
