ESSENTIAL CELL BIOLOGY 6TH
EDITION- CHAPTER 1 ACTUAL EXAM
2025/2026 QUESTIONS AND 100%
CORRECT ANSWERS
cell - CORRECT ANSWER-Small, membrane-enclosed units filled with a
concentrated aqueous (watery) solution of chemicals and provided with
the ability to create copies of themselves by growing and then dividing
in two
solitary cells - CORRECT ANSWER-simplest forms of life
Why do cells differ in multicellular organisms? - CORRECT ANSWER-
Because of the division of labor between cells
What are the similar characteristics of all cells? - CORRECT
ANSWER-They are composed of the same molecules -> participate in
the same types of chemical reactions, genetic information (form of
, genes) is carried in DNA molecules -> written in the same chemical
code -> constructed out of the same chemical building blocks, and
replicated in the same way when a cell or organism reproduces.
How do viruses reproduce, since they can't reproduce on their own like
living cells can? - CORRECT ANSWER-They parasitize the
reproductive machinery of the cells that they invade to make copies of
themselves.
Why are viruses generally not considered to be living? - CORRECT
ANSWER-Because they can't reproduce on their own, they need a host
cell.
fixed tissue preserved tissue by pickling in a reactive chemical
solution.
transmission electron microscope - CORRECT ANSWER-An electron
microscope used to study the internal structure of thin sections of
cells
scanning electron microscope - CORRECT ANSWER-An electron
microscope used to look at the surface detail of cells and other
structures
