Cell division in which the nucleus divides into nuclei containing the same
number of chromosomes - ANS✔✔---Mitosis
The synthesis phase of the cell cycle; the portion of interphase during
which DNA is replicated. - ANS✔✔---S Phase
The second gap, or growth phase, of the cell cycle, consisting of the portion
of interphase after DNA synthesis occurs.
Growth and preparation for mitosis - ANS✔✔---G2 Phase
First and longest phase of mitosis, during which the chromosomes become
visible and the centrioles separate and take up positions on the opposite
sides of the nucleus - ANS✔✔---Prophase
,Second phase of mitosis, during which the chromosomes line up across the
center of the cell - ANS✔✔---Metaphase
The resting phase of mitosis. Cell grows, performs its normal functions, and
prepares for division; consists of G1, S, and G2 phases - ANS✔✔---
Interphase
Cells that have left the cycle and cease dividing for a long time (or
permanently) - ANS✔✔---G Zero (G0) Phase
The first gap, or growth phase, of the cell cycle, consisting of the portion of
interphase before DNA synthesis begins. - ANS✔✔---G1 Phase
Division of the cytoplasm during cell division - ANS✔✔---Cytokinesis
Cell division that produces reproductive cells (gametes) in sexually
reproducing organisms - ANS✔✔---Meiosis
Compare and Contrast Mitosis and Meiosis - ANS✔✔---Mitosis produces
two diploid (2n) somatic cells that are genetically identical to each other
and the original parent cell, whereas meiosis produces four haploid (n)
gametes that are genetically unique from each other and the original parent
(germ) cell.
Number of Chromosomes in Humans... - ANS✔✔---46
Haploid Number of Chromosomes In Humans - ANS✔✔---23
, The third phase of mitosis, during which the chromosome pairs separate
and move toward opposite poles - ANS✔✔---Anaphase
The final phase of cell division, between anaphase and interphase, in which
the chromatids or chromosomes move to opposite ends of the cell and two
nuclei are formed. - ANS✔✔---Telophase
Control center of the cell; a part of the cell containing DNA and RNA and
responsible for growth and reproduction - ANS✔✔---Nucleus
Processes and transports proteins made at attached ribosomes;
synthesizes phospholipids - ANS✔✔---Rough Endoplasmic Reticulum
(RER)
A cell organelle that helps make and package materials to be transported
out of the cell - ANS✔✔---Golgi Complex
Cell organelle filled with enzymes needed to break down certain materials
in the cell - ANS✔✔---Lysosomes
Produce hydrogen peroxide, detoxifies harmful substances, oxidizes fatty
acids, and protects cell from free radicals - ANS✔✔---Peroxisomes
