Front 14

Factors affecting photosynthesis

Front 15

What is the difference between an autotroph and a heterotroph?

Back 15

Autotrophs produce their own food from the substances available in their surroundings using light (photosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms, both plants and animals, for nutrition

Back 17

chloroplasts

Front 18

What are the two stages of photosynthesis?

Back 18

Light dependent reactions and dark dependent reactions

Front 19

Light dependent reactions

Back 19

light energy is captured by pigments and converted to the chemical energy of ATP and NADPH

Front 20

Dark dependent reactions

Back 20

energy of ATP and the electrons of NADPH are used to make glucose from CO2

Front 21

What two molecules link both stages? (may be incorrect)

Back 21

Carbon dioxide and oxygen

Front 22

Why are chlorophyll important in photosynthesis

Back 22

it makes it possible for plants to convert carbon dioxide and water, in the presence of sunlight, into glucose and oxygen. Chlorophyll produces energy in the form of sugary carbohydrates, which will power all of the plant's essential growth and development. It also gives plants it's green color.
