5 True/False questions
endoplasmic reticulum (ER) → An extensive membranous network in a eukaryotic cell, continuous with the outer nuclear membrane and composed of ribosome-studded (rough) and ribosome-free (smooth) regions.
nuclear envelope → A double membrane, perforated with pores, which encloses the nucleus and separates it from the rest of the eukaryotic cell.
transmission electron microscope → A microscope that uses an electron beam to study the surface architecture of a cell or other specimen.
Vesicle → A sac made of membrane in the cytoplasm of a eukaryotic cell.
peroxisome → A threadlike, gene-carrying structure found in the nucleus of a eukaryotic cell and most visible during mitosis and meiosis; also, the main gene-carrying structure of a prokaryotic cell. Chromosomes consist of chromatin, a combination of DNA and protein.
