BIO 1001 EXAM 2 (Jariel) || All Answers are Flawless.
cells with different volumes or sizes, compare their surface area and their surface area to volume
ratio correct answers large cells have greater surface area (SA) than smaller cells; large cells
have lesser SA per volume than small cells ; smaller the cells, the greater surface area per
volume; small cells react faster than large cells
what cell structures or components do prokaryotic and eukaryotic cells have in common? correct
answers plasma membrane, DNA, ribosomes and cytosol
enumerate the structures in prokaryotic cells, give the function of each structure? correct answers
bacteria and archaea are prokaryotic cells, have no nucleus;
differentiate fimbriae from cilia correct answers used by bacteria to adhere to one another and to
substances in the environment ; cilia work more like the oars of a boat.
enumerate the structures in eukaryotic cells, give the function of each structure? correct answers
distinguished by having a membrane-enclosed nucleus and many membrane-enclosed organelles
that perform specific functions
enumerate the structures found in plant cells, but are not present in animal cells correct answers
chloroplasts, central vacuoles, cell wall,
and plasmodesmata
enumerate the structures found in animal cells, but are not present in plant cells correct answers
has a rigid cell wall that protects and provides skeletal support that helps keep the plant upright.
enumerate the structure of the endomembrane system correct answers the membranes within a
eukaryotic cell are part of the endomembrane system; these organelles interact in the synthesis,
distribution, storage and export of molecules.
, the site of protein synthesis is correct answers ribosomes
differentiate rough ER from smooth ER correct answers produces membranes and ribosomes on
its surface make membrane and secretory proteins (insulin, type 1 diabetes); has enzymes that
synthesize lipids, oils, phospholipids, steroids, sex hormones and cholesterol) (ovary / testis,
liver and muscle)
differentiate vesicle from vacuole correct answers vacuole- large vesicles that have a variety of
functions - contractile vacuoles release excess water to the outside of the cell - plant cells contain
a large central vacuole that stores molecules and wastes and facilitates growth. vesicle- ......
describe how endomembrane system transport proteins from rough ER, to golgi apparatus to
vesicles, and to plasma membrane correct answers the Golgi receives transport vesicles budded
from the ER that contain proteins synthesized by bound ribosomes, the Golgi finishes processing
the proteins and dispatches transport vesicles to the plasma membrane where the proteins are
secreted.
the function of nucleolus is correct answers produces ribosomes
differentiate lysosome from peroxisome correct answers lysosomes house hydrolytic enzymes
that break down or digest ingested substances and damaged organelles; peroxisomes are
metabolic compartments that do not originate from the endomembrane system
the organelle that is the site of cellular respiration is _______ and the organelle that is the site of
photosynthesis is _________. correct answers mitochondria , chloroplasts
based on the endosymbiont theory, mitochondrion evolved from ____ and chloroplast from
______. correct answers small prokaryotes, larger cells
what are the three organelles that have two membranes? correct answers ..
