CELL SIZE COMPARISON MODELS WORK WITH YOUR TABLE PARTNER YOU WILL FILL OUT YOUR OWN HANDOUT FOR DATA TABLE AND QUESTIONS YOU WILL SHARE ONE HANDOUT OF THE PATTERNS FOR CELL COMPARISON WORK ON THE CUTTING AND GLUING TOGETHER YOU HAVE 15 MINUTES TO FINISH THE CUBES AND ANSWER THE QUESTIONS ON HANDOUT!

THURSDAY LEARNING OBJECTIVE: HOW ARE THE TERMS CHROMATIN, CHROMOSOMES AND SISTER CHROMATIDS RELATED ENTRY TASK: WHAT ARE SOME DIFFERENCES BETWEEN SEXUAL AND ASEXUAL REPRODUCTION?

REPRODUCTION ASEXUAL DONE BY SOMATIC OR BODY CELLS DONE ALSO BY UNICELLULAR ORGANISMS CREATES IDENTICAL DAUGHTER CELLS REPRODUCTION IS QUICK AND PRODUCES LARGE QUANTITIES OF OFFSPRING SEXUAL DONE BY GAMETES OR SEX CELLS CREATES GENETICALLY DIFFERENT DAUGHTER CELLS GENETIC DIVERSITY HELPS ENSURE SURVIVAL OF SPECIES – ALLOWS FOR QUICK ADJUSTMENTS TO CHANGING ENVIRONMENT

PLAN OF THE DAY CHROMOSOMES WORK ON VOCABULARY FOLDABLE

What do we need for cell division? Chromatin: a mass of DNA found in the nucleus

What do we need for cell division? Chromosome: a compacted piece of chromatin that is used for cell division Sister Chromatids: A pair of identical Chromosomes Centromere: The center section where the sister chromatids are connected Sister chromatids Centromere TEM 36,600 

DNA supercoil

LE 8-4 Sister chromatids Centromere TEM 36,600  Sister chromatids Chromosome distribution to daughter cells Chromosome duplication

10.2 vocabulary (p. 279) In your journal, write the definition and do a diagram/drawing for the vocabulary words in section 10.2 DUE MARCH 16

FRIDAY 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. Cell division

The Cell Cycle: series of events that cells go through from “birth” to reproduction Cell division

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 I NTERPHASE P ROPHASE P ROMETAPHASE Kinetochore Fragments of nuclear envelope Centrosome Early mitotic spindle Chromatin Centrosomes (with centriole pairs) LM 250  Nucleolus Nuclear envelope Plasma membrane Chromosome, consisting of two sister chromatids Centromere 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

LE 8-6b M ETAPHASE A NAPHASETELOPHASE AND C YTOKINESIS Metaphase plate Spindle Daughter chromosomes Nuclear envelope forming Cleavage furrow Nucleolus forming

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 A cell plate forms between the two nuclei Cleavage furrow Cleavage furrow Daughter cells Cleavage furrow Contracting ring of microfilaments SEM 140 

Cytokinesis in plant cells Formation begins with a disc containing cell wall materials A cell plate forms between the two nuclei Cell wallNew cell wall Daughter cellsCell plateVesicles containing cell wall material

TO DO NOW WORK ON THE MITOSIS HANDOUT 1.READ PAGE 46 2.COLOR THE DIFFERENT STAGES OF MITOSIS (FOLLOW INSTRUCTIONS ON PAGE 46) WHEN FINISHED, I’LL CHECK YOUR WORK WORK ON VOCABULARY FOLDABLE
