●● sexual reproduction.
Answer: A reproductive process that involves two parents that combine
their genetic material to produce a new organism
●● cell cycle.
Answer: series of events in which a cell grows, prepares for division,
and divides to form two daughter cells
●● Mitosis.
Answer: cell division in which the nucleus divides into nuclei containing
identical DNA
●● Chromatin.
Answer: loose combination of DNA and proteins that is present during
interphase
●● chromosome.
Answer: condensed DNA formed from chromatin as a cell prepares to
divide
,●● Prophase.
Answer: first and longest phase of mitosis in which chromosomes
become visible, nuclear envelope dissolves, centrioles form the spindle
●● Metaphase.
Answer: second phase of mitosis, during which the chromosomes line up
across the center of the cell
●● Anaphase.
Answer: the third phase of mitosis, during which the replicated
chromosome pairs separate and move toward opposite poles
●● Telophase.
Answer: the final phase of mitosis in which two nuclei are formed;
chromosomes return to chromatin, spindle disappears
●● Cytokinesis.
Answer: division of the cytoplasm to form two separate daughter cells
●● Interphase.
Answer: cell grows, performs its normal functions, and prepares for
division; consists of G1, S, and G2 phases
, ●● G1 phase.
Answer: first stage of interphase in which cell grows, replaces organelles
and performs its normal functions
●● S phase.
Answer: The synthesis phase of interphase; the middle portion during
which DNA is replicated.
●● G2 phase.
Answer: The second growth phase of the cell cycle, consisting of the
portion of interphase before cell division occurs.
●● cell membrane.
Answer: thin, flexible barrier around a cell; regulates what enters and
leaves the cell
●● phospholipid.
Answer: A lipid made of a phosphate head and two lipid (fatty acid)
tails; forms cell membranes.
●● phospholipid bilayer.
Answer: a thin membrane made of two layers of phospholipid molecules
