Question

Although there are many distinct prokaryotic species, most have a small range of shapes, sizes, and growth rates. Which of the following characteristics are not observed in prokaryotes?

(a) a highly structured cytoplasm
(b) endoplasmic reticulum
(c) the ability to divide rapidly
(d) a cell wall

Answer 1

When considering characteristics not observed in prokaryotes, it is important to note that prokaryotic cells do not have a highly structured cytoplasm or an endoplasmic reticulum; these are features of eukaryotic cells.

Step-by-step explanation:

The question asks which characteristics are not observed in prokaryotes. Prokaryotic cells are unicellular organisms without organelles enclosed by membranes. Consequently, they lack a nucleus, instead having their genetic material in a nucleoid. They do have a cell wall, which gives them shape and protection, as well as a plasma membrane, cytoplasm, ribosomes, and in some cases, other structures like flagella, pili, and a protective capsule. However, prokaryotes do not have a highly structured cytoplasm or an endoplasmic reticulum, which are characteristic of eukaryotic cells.
