Caffeine can have various effects on plant growth. It has been found to enhance seed germination and stimulate enzymatic activity in seeds, resulting in faster and more uniform germination. Caffeine also promotes chlorophyll production, which can boost plant growth rates. An experiment was conducted that found the greatest effect on plant growth occurred when the caffeine solution concentration was 0.14, as the plants grown in this concentration demonstrated the fastest growth rate.

Caffeine?
C
a
ff
eine is a naturally occurring
compound that can have various

ects on plants, including promoting
growth under certain conditions.

The Effects of
Caffeine
How does caffeine affect
plant growth rates?
Conclusion：
B
ased on our discussion, it has been proven that Ca
ff
eine
does a
ff
ect boost plant growth.
When the concentration of ca
ff
eine solution was 0.14, the e
ff
ect on
plants was the greatest, and the growth rate of plants became the
fastest.

What does
caffeine have?
C
a
ff
eine is a natural compound that
can help plants grow better by
speeding up seed germination and
boosting chlorophyll production.
Process：
This is a picture of what the plants looked like before the experiment started,
and then we added di
ff
erent concentrations of ca
ff
eine to the six plants. See
if there is a di
ff
erence in the rate of plant growth after a period of time.
We use an electronic scale to measure
how much ground co
ff
ee is needed. We
add the same amount of water (20ml of
water per cup) to di
ff
erent amounts of
ground co
ff
ee, and
fi
nally stir it all
together.
The co
ff
ee
solution is
poured into
marked POTS
of plants, which
help us identify
each plant.
