BI 121 GRCC Lab SPOs 2: Microscope, Cell Structure &
Mitosis questions with verified answers
Anaphase Ans✓✓✓ Third stage of mitosis, during which sister
chromatids separate into two new nuclear regions of a diving cell
Arm Ans✓✓✓ Used to support the microscope when carried
Cell membrane (plasma membrane) Ans✓✓✓ Membrane surrounding
all animal cells, composed of a lipid bilayer interspersed with various
molecules
Centrioles Ans✓✓✓ small, self-replicating organelle that provides the
origin for microtubule growth and moves DNA during cell division
Chromatin Ans✓✓✓ Substance consisting of DNA and associated
proteins
Chromosome Ans✓✓✓ condensed threads of genetic material formed
from chromatin as a cell prepares to divide
Cilia Ans✓✓✓ small appendage on certain cells formed by
microtubules and modified for movement of materials across the
cellular surface
, Cleavage furrow Ans✓✓✓ The first sign of cleavage in an animal cell; a
shallow groove in the cell surface near the old metaphase plate.
Coarse focus knob Ans✓✓✓ Brings an object into focus at low or
medium power
Condenser Ans✓✓✓ focuses light through the specimen
Cytoplasm Ans✓✓✓ Internal material between the cell membrane and
nucleus of a cell, mainly consisting of a water based fluid called cytosol,
within which are all the other organelles and cellular solute and
suspended materials
Daughter chromosomes Ans✓✓✓ During mitosis, the separated
chromatids from the beginning of anaphase onward.
Fine focus knob Ans✓✓✓ brings an object into focus at high power
Flagellum (tail) Ans✓✓✓ a slender threadlike structure, especially a
microscopic whiplike appendage that enables many protozoa, bacteria,
spermatozoa, etc., to swim.
Golgi apparatus Ans✓✓✓ cellular organelle formed by a series of
flattened, membrane bound sacs that functions in protein modification,
tagging, packaging, and transport
