Question

Look at the following figure of chloroplast and choose the correct combination of statements.
i. Light reaction of photosynthesis occurs in Y.
ii. Dark reaction of photosynthesis occurs in X.
iii. X is known as thalakoid.
iv. Y is known as granum.
v. Z is known as granum.

• A. i, ii, and iv
• B. ii, iii, and iv
• C. iii, iv and v
• D. ii, iii, iv, and v

Answer 1

The correct option is A i, ii, and iv

Light reactions need light to produce organic energy molecules (ATP and NADPH). They are initiated by colored pigments, mainly green colored chlorophylls. Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called glycolysis Benison Cycle, and it occurs in the stroma.

So, the correct option is 'i, ii, iv'.
