• cristae

Answer 1

The individual flattened stacks of membranous structures inside the chloroplasts are known as thylakoids.

Explanation:

Thylakoids are the individual, flattened, disc-like membranous sacs inside a chloroplast that contain chlorophyll molecules to trap light energy. When these individual thylakoid discs stack on top of one another like a pile of coins, the entire column or stack is collectively referred to as a granum (plural: grana). In contrast, stroma is the fluid matrix surrounding these stacks, and cristae are internal folds found inside mitochondria.
