Biology—Honors
Overview: This unit
examines the processes of
mitosis and meiosis and
their roles in growth and
reproduction.
Unit Title Set: 6 Cell Growth and Reproduction
MITOSIS AND MEIOSIS H—7 Days
Unit Essential Question: How do new cells arise
from the division of pre-existing cells?
Unit Concepts As Guided Reading
*What students need to know






Cell cycle in a non-reproductive, eukaryotic cell
o Interphase
 G1
 S
 G2
o Nuclear division
 Mitosis
o Cytokinesis
 Plant vs. animal cell
Phases of mitosis: prophase, metaphase, anaphase, telophase
Phases of meiosis in diploid, germ-line stem cells
Importance of mitosis and meiosis
Outcomes of mitosis and meiosis
Importance of chromosome composition and number in controlling phenotype
Unit Competencies As Do Now’s
* What students need to be able to do (skills)
1. Describe the events that occur during the cell cycle.
6. Compare and contrast the processes and outcomes of mitotic and meiotic nuclear divisions.
7. Describe processes that can alter composition or number of chromosomes (chromosomal
mutations).

Every reading assignment is expected to be completed BEFORE you come to class. Confused about the
reading? Prepare questions to ask in class AS YOU READ.
Be a Scout and Be Prepared…Reading quizzes may be given at ANY time.
Homework is due ON THE DUE DATE (Sectionals—Turn in on the due date…Field trips and
illnesses—turn in on your first day back.).
Do Now’s are to be completed in class and turned in THAT BLOCK. (Absent??—Turn in first day
back. Questions on the reading that goes with the Do Now??—Turn in written question specifying
what you don’t understand. Be specific. Don’t say, “I don’t get it”.)
Vocabulary understanding is necessary. Attend to the words at the beginning of each chapter, or words
that you encounter that are new to you.
6. **In order for you to participate in structured activities and labs, you must have
your Guided Reading up-to-date as well as your vocabulary.

Cell Growth and Reproduction—Vocabulary
Title the middle column, ‘Mitosis’ and the right column ‘Meiosis’. Put an ‘X’ in
the appropriate column(s) for all words that describe each.
Choose ten words from Mitosis and ten words from Meiosis.
Use plain paper to make four blocks each, a total of five pieces of paper.
Write the word VERY LARGE in highlighter/magic marker on one side, and the
definition in smaller pencil print on the back.
Words will be used to play ‘hopscotch’.

OTHERWISE DIRECTED!
8.1 Chromosomes: Chromosome Structure and Chromosome Number
Directions: Do A or B. Mark an ‘X’ on the line at A or B to show your choice.
___________A. Compare and Contrast It: Make a 3-column (Haploid/Both/Diploid)
chart comparing and contrasting Haploid and Diploid cell reproduction.
___________B. Make an outline: for your reading (you don’t need sentences in an
outline). Use the following skeleton set-up for it. 1. Chromosome Structure, 2.
Chromosome Numbers, 2a. Sex Chromosomes and Autosomes, 2b. Diploid and
Haploid Cells.
