Photosynthesis

Where does Photosynthesis take place in a plant cell?

• Nucleus

• Chloroplast

• cytoplasm

• mitochondria

Pigment in green plants that capture the energy in sunlight is called __________

• Greenplasts

• chlorophyll

• stomata

• chloroplasts

Which of the following is the correct equation for photosynthesis?

• CO2 + light + H2O ---> O2 + Sugar

• CO2 + sugar + water --> O2 + light

• O2 + light + water ---> sugar + CO2

• CO2 + O2 + light ---> sugar + water

Where do plants get the energy for photosynthesis to take place?

• nutrients in the soil

• the sun

• chlorophyll

• bee pollination

What gas  do plants give off after conducting photosynthesis that humans/animals need in order to live?

• Oxygen
• Carbon
• Nitrogen
• Hydrogen

The products of photosynthesis are...

• glucose and oxygen

• carbon dioxide and water

The reactants to photosynthesis are...

• glucose and oxygen

• carbon dioxide and water

What is the role of Chlorophyll in photosynthesis?

• It breaks the hydrogen bonds in water molecules

• It converts light energy into chemical energy contained in bonds

• It releases absorbs green light waves and reflects all of the other ones

• it provides energy for the light dependent reactions

What colour of light is best absorbed by plants?

• Red and blue

• Green and Yellow

• Red and green

• Blue and green

• Only green

Red and blue light support the highest rates of photosynthesis because …

• Chlorophylls absorb light of these wavelengths more than other wavelengths.

• These are the only wavelengths that carotenoids cannot absorb.

• Light of these wavelengths have the highest energy in the visible spectrum.

• Light of these wavelengths activate the ATP synthase enzyme.
