Photosynthesis (UPDATED)

What is the main sugar produced by plants during photosynthesis?

• Fructose

• Sucrose

• Glucose

• Lactose

Which pigment in plants primarily absorbs red and blue light, and reflects green light, making plants appear green?

• Carotene

• Anthocyanin

• Xanthophyll

• Chlorophyll

What are the two main stages of photosynthesis that occur in the chloroplast?

• Glycolysis and Krebs Cycle

• Light-Dependent Reactions and Light-Independent Reactions

• Fermentation and Electron Transport Chain

• Carbon Fixation and Water Absorption

How do cacti adapt to their hot, dry environments to perform photosynthesis efficiently?

• They have very large leaves to capture more sunlight.

• They open their stomata during the day to release excess water.

• They perform CAM photosynthesis, opening stomata at night to store carbon dioxide.

• They absorb water directly from the air through their stems.
