Do Now: Warm-Up Notebook Date Title of Activity 1/20 Chromosomes Page # 82 HW: 1) Quarterly Exam Tuesday 1/26 (periods 1 & 7) and Wednesday 1/27 (period 5) – Review Sessions Monday 1/25 AM & PM 2) Plant Packet due Monday, February 1st!!! (follow calendar of deadlines) Aim #48: How can we compare animal and plant cell mitosis? Mitosis Review What are the stages of Mitosis? Interphase Prophase Metaphase Cytokinesis Anaphase Telophase Mitosis Review Place the following events of mitosis in the correct order. a.sister chromatids align along the metaphase plate b.the cell begins to cleave c.the nuclear membrane breaks up d.DNA begins to condense e.sister chromatids separate dcaeb What is Interphase? How do we know the cell is in Interphase? The part of the cell cycle that includes: G1, S, and G2 phase. 1) The chromosomes are not visible. 2) The nuclear membrane is intact. Plant Cells vs. Animal Cells Which are plant cells and which are animal cells? Animal Cells Cell Wall Plant Cells Plant Cell Mitosis What phase is this? Interphase How do you know? 1) Nuclear membrane is visible 2) Chromosomes aren’t visible Nucleus Which cells are going through mitosis? Plant Cell Mitosis What Phase is this? Prophase How do you know? 1) Chromosomes become visible 2) Nuclear membrane is disappearing 3) Spindle Fibers begin to form Plant Cell Mitosis What Phase is this? Metaphase How do you know? 1) Chromosomes line up along center of the cell 2) Each chromosome is connected to a spindle fiber at the centromere Plant Cell Mitosis What phase is this? Anaphase How do you know? 1) The spindle fibers separate the chromatids into individual chromosomes and they are moved apart. Plant Cell Mitosis What phase is this? Telophase How do you know? 1) The chromosomes gather at opposite ends of the cell. 2) Two new nuclear membranes form. 3) The chromosomes lose their distinct shapes. Plant Cell vs. Animal Cell Mitosis How is plant cytokinesis different than animal cell cytokinesis? In an animal cell, the cytoplasm pinches off. What process is this? Cytokinesis In plants, a Cell Plate forms across the middle of the cell. Plant Cell vs. Animal Cell Mitosis Animal Cell Centrioles Plant Cell Plant cells have no centrioles Animal vs. Plant Cell Mitosis Animal vs. Plant Cell Mitosis Animal vs. Plant Cell Mitosis Amoeba Sisters Mitosis
