Concept explainers
Identify the cell structure or organelle described by each of the following statements.
a. A stack of 3-1 0 membranous discs, with vesicles.
b. A continuation of the nuclear envelope forms this ribosome-covered cytoplasmic organelle.
c. In nondividing cells, the highly coiled parts of chromosomes form this type of chromatin.
d. This type of endoplasmic reticulum is a network of hollow tubes involved in lipid
e. This is a cluster of eight histone molecules and the DNA strand that wraps them.
f. These are the cytoskeletal rods with the thickest diameter (choo se form microfilaments, microfilaments, intermediate filaments).
g. The only organelle with DNA and cristae.
h. This energy-Producing organelle is Probably descended from bacteria.
i. Protein synthesis occurs at this organelle.
