YUM!!!
What would these
make/produce?
Reactants are like the ingredients.
They are the things you need to start
the reaction
Products are what you produce or end up with

Diffusion is the
mechanism that the
gases enter and exit the

Stoma or Stomata
Mainly
located on
bottom of
leaf.
Vascular Tissue The veins of the leaf
Xylem Carries water up the plant
(from the roots). Enters
Root hairs through
Osmosis.
Long tubes of dead cells.
Looks like a straw.
Transpiration
is essentially evaporation of water from plant leaves. (Plant Sweat)
Fun Fact: Studies have revealed that about 10 percent of the moisture found in the
atmosphere is released by plants through transpiration
-Water vapor escapes
through Stomata.
-This creates a suction
pressure in the plant
which pulls water from
the roots up the xylem to
the leaves.
Vascular Tissue cont…
Phloem Carries sugar (Sucrose) down
the plant (from the leaves)

Chlorophyll is a pigment that is made of the
element Magnesium and reflects green light.
Sunlight is captured by chlorophyll
Radiant energy for the reaction
Photosynthesis takes place in the chloroplast
Folded to make

Product:
Carbohydrate
Monosaccharide
Glucose (chemical energy)
Can be used by the
plant for energy
OR
Stored by the plant
in the form of
Starch
Polysaccharide
Since plants make this glucose (food) they are
called Producers or Autotrophs
