The Cellular Basis of Inheritance/Cell division
11/16/09
Events of Cell Cycle, Mitosis
Standards
Science Standards (PDE):
3.3.10
A. Explain the structural and functional similarities and differences found among living things.
 Explain the relationship between structure and function at the molecular and cellular
levels.
Technology (PDE):
Objective:
To explain the origins of Cancer, the two types of Cancer, and how metastasis occurs
To identify the stages of cell division and describe the activity inside the cell during cell division.
Materials, Tools, Resources:
Powerpoint, Cell Cycle Graphic Organizer, Laptops, Microscope, Mitosis slides
Homework:
R/O 8.6-8.11, study for Quiz
Learning Activities:
Warm-up: See Cell division Warm-up slides
1. Discuss Cancer WebQuest questions. Accept any questions.
2. Present Practical Mitosis powerpoint. Students record information in provided guided
notes packet. Ask questions to check for understanding throughout the presentation.
a. Guide students to draw a cell in each phase of mitosis
i. Show a real cell in each phase, and illustrate on board
b. Stress that M-phase (Mitotic phase) is NOT same as Mitosis… M phase is cell
division (mitosis and cytokinesis)
3. Students record information about the stages in Mitosis.
a. Show students Mitosis Hand signals
b. Show online animations:
i. Cells Alive Mitosis
ii. John Kyrk animation

iii. Hybrid Medical:

4. Students identify phases of mitosis of onion cells.
a. Provide marker and transparency of onion cell slides to pairs of students. Point
out observable features to help them identify cells in different stages. Students
use marker to identify cells in each stage.
b. Teacher circulates around the room checking for understanding.
5. Onion root tip Observation lab

a. Students complete both parts of the lab (may only get to one part today)
b. Part I, sketch and label ONE cell found in each stage. Provide descriptions to
help identify the cell at a later time.
c. Part II, count and record the number of cells in each stage as provided through
Web activity. Calculate percentage of time spent in each phase.
Closure: Review Mitosis Hand Signals, ask about the events in each stage.
