Spherical or tubular membranes which separate the material present in endoplasmic reticulum from that of cytoplasmic material are called
Correct answer: B. Cisternae
- A. Cytosol
- B. Cisternae
- C. Lysosomes
- D. Cristae
Explanation
The correct answer is cisternae. Cisternae are the structural components of the endoplasmic reticulum, which are either spherical or tubular in shape, and they serve to separate the content within the ER from the cytoplasm. This distinct separation allows for the proper functioning and processing of proteins and lipids within the ER. The other options are incorrect because they refer to different structures: cytosol is the fluid part of the cytoplasm, lysosomes are involved in digestion and waste processing, and cristae are specific to mitochondria.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
