The distribution of lipids in the plasma membrane of eukaryotes is symmetrical.

Endoplasmic reticulum (ER)with many ribosomes attached is called __________ ER,whereas endoplasmic reticulum that is mostly devoid of ribosomes is called __________ ER.

Coated pits containing clathrin do not permit concentration of ingested macromolecules prior to endocytosis.

The inner membrane system of chloroplasts consists of flattened sacs called __________ that form stacks called __________.

The endoplasmic reticulum is composed of flattened sacs called

Eukaryotes usually have more than one chromosome for the storage of genetic information.

Lysosomes maintain an acidic environment by actively pumping protons into their interior.

The major difference between the vacuoles of eukaryotes and the inclusion bodies of prokaryotes is that the former are membrane-bound whereas the latter are not. ASM
