Mitosis: cell division in which the
nucleus divides
Mitosis forms two daughter cells that
are exactly the same as the parent cell
Genetics (cont)
Date:
III.Mitosis is cell division in which
the nucleus divides
A. Daughter Cells (formed by
mitosis) have exact copies of
the parent cell
chromosomes
Summary:

Summary: Mitosis makes exact copies of parent cell

Meiosis: cell division that produces
reproductive cells (have half of the
genetic material of the parent cell).
Genetics (cont)
Date:
IV. Meiosis—cell division that
produces reproductive cells (have
half of the genetic material of the
parent cell).
Summary:
Reproductive Cells: Egg (female)
and Sperm (male)
Plant Sperm
Seedless Vascular Plants and
Bryophytes produce sperm and egg
Bryophytes
Mosses, Liverworts & Hornworts
Bryophytes don’t
produce seeds!
They require a
thin film of water
for sperm to swim
in.

GP: Modeling Mitosis and Meiosis
1. Get 4 pairs of matching pipe cleaners.
2. Place 4 pipe cleaners onto the desk (these
represent chromosomes in the nucleus)
3. Follow along with me as we describe mitosis
and meiosis
GP: Modeling Mitosis and Meiosis
4 chromosomes (2 pairs of chromosomes)
INP: Put Mitosis and Meiosis in
your vocabulary journal (page 2)
(When you finish this, add color and finish the rest of your vocabulary words)
Front Cover
1. Draw and color a strand of
DNA for the cover of your
Genetics Vocabulary
Journal.
2. Label these parts
1. Nitrogen Base
2. Sugar and phosphate
backbone
3. Adenine—Thymine
4. Cytosine—Guanine
3. When you finish, work on
your vocabulary words
from yesterday (add color)
