____ is a stack of thylakoids
|
|
Granum
|
|
|
Stomata
|
|
|
Stroma
|
|
|
Chloroplast
|
Explanation:
Detailed explanation-1: -Abstract. Chloroplasts contain a system of membrane sacs, the thylakoids, some of which are stacked to form grana (singular, granum), whereas others float freely in the stroma. It is on the thylakoid membranes that the electron carriers necessary for photosynthesis reside.
Detailed explanation-2: -Granum is a basic structural unit of the thylakoid membrane network of plant chloroplasts. It is composed of multiple flattened membranes forming a stacked arrangement of a cylindrical shape.
Detailed explanation-3: -So, the correct answer is ‘When stacked, each thylakoid is able to increase their total surface area which allows more electron transport chains to be embedded into each thylakoid membrane’
