Chapter 6 Photosynthesis

Based on the cycle of photosynthesis and cellular respiration, one can say that the ultimate original source of energy for all living things on Earth is

the sun

The process whereby plants capture energy and make complex molecules is known as

photosynthesis

Suspended in the fluid stroma of chloroplasts

stacks of thylakoids called grana

light reactions : thylakoids ::

Calvin cycle : stroma

The role of chlorophyll in photosynthesis is to

absorb light energy

When light strikes an object, the light will be

reflected, absorbed and transmitted

Chlorophyll is green because

it reflects green wavelengths of light

The source of oxygen produced during photosynthesis is

water

The major products of photosynthesis that is released into the atmosphere is

oxygen

What process occurs in the thylakoid membrane

light reactions

The energy used in the Calvin cycle for the production of carbohydrate molecules comes from

ATP made in the light reactions of photosynthesis

During photosynthesis, the series of reactions that create the glucose needed for energy and growth is called

the Calvin cycle

All organic molecules contain carbon atoms that ultimately can be traced back in the food chain to

carbon dioxide from the atmosphere

The main pigment associated with the two photosystems is

chlorophyll

Pigments that absorb other wavelengths and appear yellow and orange

accessory pigments
