BIOLOGY HOW LIFE WORKS 4TH EDITION
EXAMINATION TEST 2026 QUESTIONS WITH
ANSWERS GRADED A+
◉ cytoplasm. Answer: entire contents of cell other than nucleus
◉ cytosol. Answer: jellyish internal environment of the cell that
surrounds the organelles inside the cell membrane
◉ How are organelles connected? Answer: by vesicles or membrane
bridges
◉ vesicles. Answer: small-membrane enclosed sacs that transport
substances
◉ vesicles form by. Answer: forming off an organelle, taking a piece of
the membrane and internal contents of organelle, fuse with another
organelle or the membrane, unloading their contents
◉ endomembrane system. Answer: made of interconnected membranes
, ◉ what is included in the endomembrane system? Answer: nuclear
envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, cell
membrane, and vesicles
◉ Where do molecules within the endoplasmic reticulum go? Answer:
stay inside it, end up in interior of Golgi apparatus, or go outside the cell
by fusing with a vesicle
◉ exocytosis. Answer: when a vesicle fuses with the cell membrane, can
empty its contents there or deliver proteins
◉ endocytosis. Answer: vesicle buds off from cell membrane, enclosing
material from outside and bringing it in
◉ nuclear envelope. Answer: defines the boundary of the nucleus,
consists of two membranes (lipid bilayers),
◉ nuclear pores. Answer: openings in inner and outer membranes of
nuclear envelope that connect them to each other, allow molecules to
move into and out of nucleus
◉ ribosomes. Answer: site of protein synthesis
◉ protein synthesis. Answer: process in which amino acids are
assembled into polypeptides guided by the information stored in mRNA
