Something

Transport water from the root to the leaf quickly || Stem: xylem inside, phloem outside Starch as a storage substance: immobile, insoluble, inert Ethanol: destroys fat of plasma membrane and hence chlorophyll will leak out of the leaf
 * Palisate Mesophyll || Arranged perpendicular to the upper epidermis so that more sunlight is captured ||
 * Spongy Mesophyll || Has large air spaces/intercellular space to allow more air to enter and found at the bottom to allow gaseous exchange ||
 * Leaf || Leaf is thin and flat, so surface area is large to volume, so air can pass through easily and the air entered through the stoma has access to the mesophyll ||
 * Leaf structure: veins, etc || Large surface area to volume ratio exposed to sunlight ||
 * Vascular Bundle || Provide support to prop up the leaf

As light intensity increases, rat of photosynthesis increases. There is a limit to the saturation point of sunlight
