DUE MARCH 16
FRIDAY 3-6-15
LEARNING OBJECTIVE:
HOW THE CELL CYCLE WORKS
ENTRY TASK:
• GET A MITOSIS HANDOUT FROM THE FRONT OF THE
ROOM AND START READING PAGE 46
PLAN OF THE DAY
• CELL CYCLE VIDEO
• MITOSIS HANDOUT
How do cells divide?
• Cell Cycle: an orderly sequence of events
where cells divide
• The cell cycle consists of two major phases
– Interphase (90% of the time)
– Cell division (10% of the time)
The Cell Cycle
In humans and other mammals, cells that reproduce daily have a cell
cycle that usually lasts 10 to 20 hours.
The Cell Cycle: series of events that cells go through from
“birth” to reproduction
Interphase
• Phase where all metabolic processes and
functions happen
– Ex:
•
•
•
•
•
Cellular respiration
Protein creation
Movement
Growth
Other desired function
Interphase
• Interphase is also when the cell prepares for
cell division
– Ex:
•
•
•
•
Increases proteins
Duplicates organelles
Grows in size
Duplication of DNA
Cell Division
• The division phase of the cell
• There are two main parts of M phase
– Mitosis
– Cytokinesis
Cell Division
• Mitosis
– The division of a cells nucleus and DNA into two
equal parts
– Creates two daughter nuclei
• Cytokinesis
– The division of the cells cytoplasm
• Together they create two identical daughter
cells
Mitosis
• Prophase:
– Sister chromatids are formed
– Formation of spindle
– Nuclear envelope breaks down
• Metaphase:
– Sister chromatids line up
– Spindle is formed and attaching to chromosomes
LE 8-6a
INTERPHASE
Centrosomes
(with centriole pairs)
Nucleolus
Nuclear

PROPHASE
Chromatin
Plasma

PROMETAPHASE
Centrosome
Chromosome, consisting
of two sister chromatids
Centromere
Fragments
of nuclear
envelope
Kinetochore
Spindle
microtubules
Mitosis
• Anaphase:
– Separation of sister chromatids
– Spindle pulls chromosomes to either side of the
cell
• Telophase:
– Spindle breaks down
– Nuclear envelopes form (2)
– Chromosomes loosen to become chromatin
• Cytokinesis:
– Cell pulls apart to create two identical cells

Cytokinesis in animal cells
Animal
• Formation begins with
indentation
• Cell is pulled/ pinched
until it breaks apart
Plants
• Formation begins with a
disc containing cell wall
materials
Cleavage
• A cell
furrowplate forms
between the two nuclei
Cleavage furrow Contracting ring of
microfilaments
Daughter cells
Cytokinesis in plant cells
• Formation begins with a disc containing cell wall materials
• A cell plate forms between the two nuclei
Cell wall
Vesicles containing
cell wall material
New cell wall
Cell plate
Daughter cells

What is the purpose of mitosis?
Benign vs. malignant tumor
• Benign tumor:

– abnormal mass of normal cells
Malignant tumor:
• Masses of cells that result from the reproduction of cancer
cells
• Cancer
– Disease caused by cells that loose their ability to
control rate of division
