a. Lamellae
b. Cisternae
c. Stroma
d. Cristae​

Answer 1

Explanation:

b cisternae

I think so .....

Answer 2

Answer:

(b) Cisternae

Explanation:

Endoplasmic Reticulum

The endoplasmic reticulum (ER) is a large and dynamic structure that perform many roles in the cell which includes calcium storage, protein synthesis and lipid metabolism. The diverse functions of the endoplasmic reticulum are performed by distinct domains which consists of tubules, sheets and the nuclear envelope.

Cisternae

A cisterna (plural cisternae) is a flattened membrane vesicle which is found in the endoplasmic reticulum and golgi apparatus. Cisternae are an integral part of the packaging and modification processes of proteins which are occurring in the Golgi apparatus.

Lamellae

Lamellae is a sheet like membrane which is found within a chloroplast of an autotrophic cell. They usually act as a type of wall at which chloroplasts can be fixed within and achieving the maximum light possible.

Stroma

Stroma is a type of fluid which is present in the chloroplast surrounding the thylakoid membrane and helps in the synthesis of organic molecules from carbon dioxide and water.

Cristae

Cristae helps in increasing the capacity of the mitochondrion to synthesize the ATP and usually the inner membrane is folded to form cristae in mitochondria.
