Photosynthesis

Pigment which captures sunlight

• Chloroplast

• Chlorophyll

• NADH

• photon

Answer explanation

Chlorophyll holds electrons donated by water so that they can be excited by photons

Check all that are reactants in photosynthesis

• water

• CO2

• Oxygen

• Glucose

Answer explanation

reactants are on the right side with products on the left (of the arrow).

Which of the following is a particle of sunlight?

• proton

• photon

• protein

Answer explanation

A photon has both a particle and wave like nature. It is the fastest moving thing in our universe and travels at a universal speed (C)

Electron donor for the beginning of photosynthesis

• CO2

• oxygen

• photons

• water

Answer explanation

Electrons are taken from water at the begining of photosnthesis, which makes hydrogen fall off. This results in O2 (oxygen)

Organelle responsible for photosynthesis

• chlorophyll

• chloroplast

• mitochondria

• nucleus

Answer explanation

Chloroplasts are the organelle. Chlorophyll are the pigments inside. Remember, "Chlorophyll fills the chloroplasts"
