Vascular System (veins): Xylem and Phloem • There are two tubes found inside most plants: xylem and phloem. Xylem : transports nutrients and water from the roots of the plant to every area of the plant. Phloem : transports nutrients (mostly sugars that are made during photosynthesis from the leaves to the rest of the plant
Stomata Is a smallopeningonthe bottom of a leaf that gases pass in and out of (CO2, O2, H2O).
