Produce hydrogen peroxide, detoxifies harmful substances, oxidizes fatty acids,
and protects cell from free radicals - ANSWER- Peroxisomes
- Hollow, cylindrical organelle that disposes of unnecessary and damaged proteins
- Contain enzymes that break down tagged, targeted proteins into short
peptides and amino acids - ANSWER- Proteasomes
- Cell division in which the nucleus divides into nuclei containing the same number
of chromosomes - ANSWER- Mitosis
-
-
- The resting phase of mitosis. Cell grows, performs its normal functions, and
- prepares for division; consists of G1, S, and G2 phases - ANSWER- Interphase
-
-
- Cells that have left the cycle and cease dividing for a long time (or permanently) -
ANSWER- G Zero (G0) Phase
-
-
- The first gap, or growth phase, of the cell cycle, consisting of the portion of
interphase before DNA synthesis begins. - ANSWER- G1 Phase

-
-
- The synthesis phase of the cell cycle; the portion of interphase during which DNA
is replicated. - ANSWER- 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 - ANSWER- 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 - ANSWER- Prophase
-
-
- Second phase of mitosis, during which the chromosomes line up across the
center of the cell - ANSWER- Metaphase
-
-
- The third phase of mitosis, during which the chromosome pairs separate and
move toward opposite poles - ANSWER- 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. - ANSWER- Telophase
-
-
- Division of the cytoplasm during cell division - ANSWER- Cytokinesis
-
-
- Cell division that produces reproductive cells (gametes) in sexually reproducing
organisms - ANSWER- Meiosis
-
-
- Compare and Contrast Mitosis and Meiosis - ANSWER- 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.
