Connections Between Cell Division and Reproduction Compare the parent- offspring relationship in asexual and sexual reproduction. Explain why cell division is. Compare the parent-offspring relationship in asexual and sexual reproduction. Explain how prokaryotes reproduce by binary fission. The Eukaryotic Cell. C h a p t e r 8 The Cellular Basis of Reproduction and Inheritance Chapter 8 Objectives the parent-offspring relationship in asexual and sexual reproduction . Compare the structure of prokaryotic and eukaryotic chromosomes.

Cancer is a disease of the cell cycle. Malignant tumor cells spread to other tissues o Cancer Patients: Benign tumors Surgery Radiation focused high-energy radiation Malignant Tumors: Condensed form of DNA Identical sister chromatids are result of DNA Synthesis during the cell cycle Protein that holds sister chromatids together, site for spindle fiber attachment.

Usually has a centrosome with a pair of centrioles involved in cell division. Division of the cytoplasm to form two separate daughter cells. Mitosis and cytokinesis make up the mitotic M phase of the cell cycle. A double membrane across the midline of a dividing plant cell, between which the new cell wall forms during cytokinesis. Autosomes are all the other pairs: MacHD, cschmittloyd, downloads [Google: Drew Berry, Astonishing Molecular Machines. Download and show clip from 5: Use the Mitosis Video Activity online.

Spindle fibers attach to centromere 3. Others attach to each other pole to pole 4.

Centromeres of all chromosomes are lined up on the metaphase plate equatorial plane 3. Sister chromatids face opposite poles. Microtubules attached to one sister chromatid all go to one pole. Begins when the two centromeres of each chromosome come apart, separating identical sister chromatids.

Polar fibers elongate, stretching the cell. Page 5 of 12 http: Recognize the phases of mitosis from diagrams and micrographs.

Compare cytokinesis in animal and plant cells. Explain how anchorage, cell density, and growth factors control cell division. Explain how cancerous cells are different from healthy cells.

Chapter 8 Objectives

Distinguish between benign and malignant tumors and explain the strategies behind some common cancer treatments. Describe the functions of mitosis. Meiosis and Crossing Over Explain how chromosomes are paired. Distinguish between autosomes and sexchromosomes.

Modern Biology Ch. 8 NOTES Mitosis and Meiosis

Distinguish between somatic cells and gametes and between diploid cells and haploid cells. List the phases of meiosis I and meiosis II and describe the events characteristic of each phase. Recognize the phases of meiosis from diagrams and micrographs. Describe the similarities and differences between mitosis and meiosis.

Explain how the result of meiosis differs from the result of mitosis. Explain how independent orientation of chromosomes at metaphase I, random fertilization, and crossing over during prophase I of meiosis contribute to genetic variation in sexually reproducing organisms.
