Matching
Match each definition with a word.
1. Contains DNA and carries the genetic material that 2. Passing traits from parents to offspring
is copied and passed from generation to
generation. When visible it is shaped like an X.

Chromosome
3. a. The act of making copies.
b. The process whereby DNA makes a copy of
itself before cell division(mitosis). Occurs in
Interphase.

5. Process by which sex cells (sperm and eggs) are
created in the reproductive organs. The process
takes a normal body (diploid) cell divides it twice
creating four sex (haploid) cells.
4. Reproductive cells; sperm and egg cells in animals.
They have half (haploid, 23) of the normal
chromosomes found in other body cells
(diploid,46).
_________________
6. The simplest form of asexual reproduction. The
nucleus and cytoplasm of bacteria divide evenly,
creating two daughter cells.

7. When cytoplasm pinches off and the parent cell is
divided in two; usually follows mitosis and
meiosis
8. Each half of a chromosome; they form as DNA
makes a copy of itself before cell division.

9. The region in which chromatids are held together
to make a chromosome.

10. The process whereby cells reproduce by dividing
to replace old cells, heal wounds, and form
organism growth. Each new daughter cell is
identical to the parent cell.
