What are the primary products of the light reactions of photosynthesis?

• Glucose and O2

• Co2 and H2O

• ATP, NADPH, and O2

• Chromosome condensation

What is the primary structural component of the cell membrane?

• Proteins

• Cholesterol

What is the result of meiosis?

• Two genetically identical diploid cells

• Four genetically unique haploid cells

• Four genetically identical diploid cells

• Two genetically unique haploid cells
