Plant Transport System
Tubes
water-carrying
tubes(xylem)
transport water and mineral salts
to the other parts of the plant from the roots.
food-carrying
tubes(phloem)
transport food
made by the leaves
to all the other parts of the plant.
found in flower, stem, roots, fruits and leaves
Leaves
Stomata
More on the underside
than on the upperside
to minimise water loss, because upper side is expose to direct sunlight, so water can gain heat and evaporate
Small openings in leaf
allow Gaseous Exchange
during transpiration
allow carbon dioxide produce by transpiration to exit plant
allow oxygen to enter plant to respire
allow gaseous exchange during
photosynthesis to take place
(presence of sunlight)
allow carbon dioxide to enter the plant for photosyntheis
allow oxygen produce during photosynthesis to exit plant
what happen if parts of plant
transport system are removed.
with water, the leaves
can still photosynthesis and make food.
however, food made in the leaves
cannot be transported past the cut
as the food carrying tubes were removed.
hence, the food accumilated above the
cut causing the part of the stem to swell.
water absorbed by the roots
can still be transported to the leaves
as the water carrying tubes were not removed.
if there are no leaves below the cut,
the roots will eventually die
due to lack of food,
causing the plant to wither and die.
