Viewed from space, Earth offers no clues about the diversity of life forms that reside there. The first forms of life on Earth are thought to have been microorganisms that existed for billions of years in the ocean before plants and animals appeared. The mammals, birds, and flowers so familiar to us are all relatively recent, originating 130 to 200 million years ago. Humans have inhabited this planet for only the last 2.5 million years, and only in the last 200,000 years have humans started looking like we do today.

Sample Questions from the Biology 08 Photosynthesis MCQ Quiz

Question: Which molecule must enter the Calvin cycle continually for the light-independent reactions to take place?

Choices:

RuBisCO

RuBP

3-PGA

CO2

Question: Which order of molecular conversions is correct for the Calvin cycle?

Choices:

RuBP + G3P → 3-PGA → sugar
