    Aquaporins, water channels in plant cell plasma membranes, play an important role in plant survival and growth. In return, they can be important players from increased temperatures to photosynthesis in plant life.

    Moreover, solutes are also transported via plasma membranes and critical to plant growth and health. In recent years, substantial research has been carried out to elucidate highly complex transport systems of nutrients such as zinc (\(\mathrm{Zn}\)), iron (\(\mathrm{Fe}\)), and nitrogen (\(\mathrm{N}\)).

    Furthermore, osmosis and diffusion help plant water and solute uptake, respectively.

    \(\PageIndex{2}\). Big Picture


    \(\PageIndex{3}\). Vocabulary and Key Concepts


    \(\PageIndex{4}\). Test Your Knowledge

    • Assessment 1: TRUE or FALSE: Xylem is dead at maturity while phloem is alive.
    • Assessment.2: TRUE or FALSE: In phloem translocation, sugars move to organs that most needed.
    • Assessment.3: Compare and contrast osmosis, diffusion, and active transport.
    • Assessment 4: TRUE or FALSE: Guttation is loss of liquid droplets that contain substances [at night] while transpiration is loss of vapors of pure water [during the day].

    \(\PageIndex{5}\). Can You Spot These Plants?


    \(\PageIndex{6}\). Check Your Answers

    1. TRUE
    2. TRUE
    3. While all three are movement of particles, diffusion and osmosis are passive transport only
    4. TRUE
