Chapter 10 – Growth and Cell Reproduction/Sexual Reproduction and Meiosis – Test Review Know the three stages of the cell cycle and what happens in each – which is longest? o Pg 198 – Interphase, mitosis and cytokinesis o Longest – Interphase Know how cytokinesis is different in animal and plant cells – pg. 199 o Plant cells – cell plate forms o Animal cells – cytoplasm pinches Define chromosome – pg. 197 o Structure made of DNA and protein in the nucleus of a eukaryotic cell Know the phases of mitosis – PMAT – what happens to the chromosomes in each phase – be able to draw the chromosomes in each phase (pg. 199 in book) – Remember interphase and cytokinesis are NOT part of mitosis, they ARE part of the cell cycle o Prophase – Chromosomes become visible, nuclear membrane disappears o Metaphase – Chromosomes line up along the midline of the cell o Anaphase – Chromosomes split – each half pulled to opposite side of cell o Telophase – Chromosomes cluster in the center of each new cell, nuclear membrane reforms in each new cell Know what happens to the DNA during interphase o DNA doubles/duplicates Know the two types of reproduction – sexual and asexual – give an example of asexual reproduction – pg. 202 o Asexual – one parent o Sexual – two parents Know what homologous pairs of chromosomes are – pg. 202 o Chromosomes that carry the same genetic material (equivalent) Know the difference between body cells and sex cells o Mitosis occurs in body cells and meiosis occurs in reproductive cells to produce sex cells Define mitosis, define meiosis o Mitosis – stage of the cell cycle where the nucleus divides into 2 cells o Meiosis – cell division that produces sex cells with half the number of chromosomes Know the phases of meiosis – PMAT I and PMAT II – what happens to the chromosomes in each phase (pg. 204 in book) – be able to draw the chromosomes in each phase o Prophase I – Chromosomes visible, nuclear membrane disappears o Metaphase I – Homologous pairs of chromosomes line at midline of cell o Anaphase I – Homologous pairs separate and move to opposite sides of the cell o Telophase I – Nuclear membrane forms in each new cell o Prophase II – Chromosomes are still visible, but DO NOT double here o Metaphase II – Chromosomes line up at midline of cell o Anaphase II – Chromosomes separate and move to opposite sides of cell o Telophase II – 4 new daughter cells are formed (each with haploid number of chromosomes) Know the final result of mitosis and meiosis o Mitosis – 2 daughter cells – genetically identical to parent cell o Meiosis – 4 daughter cells – genetically different from parent cell Define fertilization – pg. 205 o Union of egg and sperm to create a new organism Know what haploid and diploid mean – what is the diploid number for humans and what is the haploid number for humans? – pg. 205 o Diploid – complete set of chromosomes (Humans 46) o Haploid – half set (Humans 23) Be able to complete a table comparing mitosis and meiosis – we did two in class, the blue sheet and green sheet o Review pg. 207 and sheets given in class Know what cell differentiation means and give an example – pg. 206 o Process of cell specialization NOTE: When you draw the chromosomes in each phase of mitosis and meiosis, start with Prophase where the chromosomes have already doubled (not interphase)
