7D - PHOTOSYNTHESIS AND GREENHOUSE EFFECT SECOND CHECKPOINT

Greenhouse effect and anthropogenic activities are the cause off which percentage of global warming

• 93%

• 75%

• 90%

• 95%

· Which is the key on greenhouse effect?

• Reflection of light espectrum

• Absorption of infrared rays

• Transmission of thermal energy

• Greenhouse gases

What determines the atmosphere's reflection and absorption ability

• The presence of mitochondria in plant cells

• The amount of sunlight trapped by plants

• The gases exiting in the atmosphere in small portions

• The easy transmission of solar light

People have the potential power to positively affect climate change, because

• Technogenic emissions should be cut off

• People can invent technology that help atmosphere to absorb CO2 emissions.

• Technogenic emissions can be controled and reduced sistematicaly

• Since greenhouse effect is a natural phenomenon, nature will go on

Increasing temperature, rising of sea level, reduction of rainfall, and increasing of flood and hurricanes are caused by

• Global Warming

• Greenhouse effect

• Increasing of CO2 emissions

• Greenhouse gases

Any phisiological manifestation occuring in any organism depends on

• the nature and how it regulates its self

• the nature, control and regulation of biochemical reactions.

• the nature and the way people takes care of it

• the nature and the natural processes that occur in it

If humans, animals cant survive without plants, people, animals and even plans cannot exist without

• Carbon dioxide

• Oxygen

• Energy

• Glucose

The threat of global warming is related to the rise of average annual temperature because

• regulating the earth temperatures each time is more dificult

• high temperatures are dangerous for plans and animals

• green house related environmental problems are increasing each time

• high temperatures become into an hard adaptative issue for plants

Understanding photosynthesis and respiration allow to

• learn about how to have better crops all the time

• learn about the impact of high temperatures on plant growing, resistance, immunity and breeding.

• implent new and better technologies associated with plant growing

• create new strategies associated to control the rise of worl temperature

The basis of research and global warming problems and their solutions has its practical base on

• experiments carried out on different parts of the world during the last five years

• experiments carried out on the second half of XIX century on crop photosynthesis

• Scientific and empirical experiments made throughout the years

• The observation over the enviromenment and the evolution of the species
