The light-independent reactions of photosynthesis are also known as the
Priestly Cycle
Vanhelmont Cycle
Hayes Cycle
Calvin Cycle
Which substance from light-dependent reactions of photosynthesis is a source of energy for the Calvin cycle?
NADPH
Carbon Dioxide
ADP
Water
The first process in the light-dependent reactions of photosynthesis is..
Light Absorption
ATP Formation
Electron Transport
Oxygen production
Which organelle contains chlorophyll?
Mitochondria
Vacuole
Chloroplast
Ribosome
The products of photosynthesis are
Water and sunlight
Water and oxygen
Sugars and carbon dioxide
Glucose and oxygen
The leaves of a plant appear green because chlorophyll
reflects green light
absorbs red light
absorbs green light
reflects blue light
In addition to light and chlorophyll, photosynthesis requires
Glucose and water
Carbon dioxide and Glucose
Water and oxygen
Water and carbon dioxide
One of the principal chemical compounds that living things use to store energy is
Carbon Dioxide
Oxygen
ATP
Water
