does not help desert plants to
accumulate water?
• It erodes paint, plaster, buildings.

• Process when plants produce energy and O3
What is "photosynthesis"?
out of H2O and CO2
• Process when acid rain clouds are formed
• Process in which plants produce energy and
O2, by using solar energy.
• Process in which plants produce glucose and
O2 using sunlight.
14.
What elements do plants
produce during photosynthesis?
•
•
•
•
CO2 and H2O

Ozone
Questionnaire
15.
Why is photosynthesis
active at the daytime?
16.
How does photosynthesis
reduce the amount of CO2 in the
air?
17.
What do organisms use
photosynthesis product O2 for?
18.
What is the difference
between aerobic and anaerobic
breathing?
• There is enough solar energy.
• Plants sleep during night
• Because during night plants are busy with
other processes
• Because there is enough O2
19.
What are pesticides?
•
•
•
•
• Mineral fertilizers
• Materials that combine with O2 into
greenhouse gas
• Chemicals that exterminate soil vermin and
weeds.
• chemicals that improve water quality.
It synthesizes glucose out of CO2
CO2 splits to coal and oxygen
• Pesticides prevent dead organisms from
A plant stores CO2 in its roots
20.
Why are pesticides toxic to
rotting
