Equation
for Aerobic respiration
Glucose
+ oxygen -> water +
carbon dioxide
Definition : waxy cuticle
A
waxy
, waterproof layer that cuts water loss by
evaporation
(top of leaf)
Definition
: upper eperdermiss
Singular layer of cells which allows light to pass straight through (
transparent
)
2nd
layer
Definition
:
palisade
layer
Contains
chloroplast
for
photosynthesis
to take place (3rd layer)
Definition
: vein
Contains both xylem (transports water) and
phloem
(transports sugars)
Definition
: spongy mesophyll
Irregular shaped cells which allows gas exchange- large
surface area
definition
: Lower eperdermis
Consists if tiny holes/ pores called
stomata
and allows
gas exchange
at random intervals
definition
:
guard cells
Open and close
stomata
Equation
for photosynthesis
Water + carbon dioxide ->
glucose
+
oxygen
light energy
chlorophyll
Limiting
factors : light intensity
As light
increases
the Rate of Reaction increases until it
plateus
Limiting
factors : CO2
As the concentration
increases
the rate of reaction increases till it
plateus
.
Limiting
factors :
heat energy
As the temperature
increases
, the rate of reaction
increases
until the optimal temperature is reached and enzymes denature
