The first stable product of photosynthesis is – (1) Starch (2) Sucrose (3) Phosphoglyceric acid (4) Glucose
by

1 Answer

Answer :

(3) Phosphoglyceric acid Explanation: The first product of photosynthesis is a three-carbon compound called phosphoglyceric acid and phosphoglyceraldehyde. Almost immediately, two of these join to form a glucose molecule. Certain herbaceous plants such as sugarcane, corn, and sorghum, form as the first products of photosynthesis not three-carbon but four-carbon compounds— oxalacetic, malic, and aspartic acids.
