What are the main events of the cell cycle? 3. What happens during the phases of mitosis? 4. How do daughter cells split apart after meiosis? +-----------------------------------+-----------------------------------+ | Cell Division and Chromosomes | | +===================================+===================================+ | What does growth depend on? | | +-----------------------------------+-----------------------------------+ | Cells must first make a complete | | | copy of their \_\_\_ before cell | | | division. | | +-----------------------------------+-----------------------------------+ | What are **chromosomes**? | | +-----------------------------------+-----------------------------------+ | Describe prokaryotic cells and | | | their DNA. | | +-----------------------------------+-----------------------------------+ | Describe eukaryotic cells and | | | their DNA. | | +-----------------------------------+-----------------------------------+ | Eukaryotic chromosomes contain | | | DNA tightly bound to proteins | | | called \_\_\_. | | +-----------------------------------+-----------------------------------+ | DNA + histones = \_\_\_ | | +-----------------------------------+-----------------------------------+ | What is **chromatin**? | | +-----------------------------------+-----------------------------------+ | When does chromatin condense into | | | chromosomes? | | +-----------------------------------+-----------------------------------+ | Why do we have chromosomes? | | +-----------------------------------+-----------------------------------+ | The Cell Cycle | | +-----------------------------------+-----------------------------------+ | What happens during the **cell | | | cycle**? | | +-----------------------------------+-----------------------------------+ | Describe the prokaryotic cell | | | cycle. | | +-----------------------------------+-----------------------------------+ | What are the 4 stages of the | | | eukaryotic cell cycle? | | +-----------------------------------+-----------------------------------+ | What does **interphase** consist | | | of? | | +-----------------------------------+-----------------------------------+ | What does the "M phase" | | | represent? | | +-----------------------------------+-----------------------------------+ | What happens during G1? | | +-----------------------------------+-----------------------------------+ | What happens during S? | | +-----------------------------------+-----------------------------------+ | What happens during G2? | | +-----------------------------------+-----------------------------------+ | What are the two stages of the M | | | phase (cell division)? | | +-----------------------------------+-----------------------------------+ | What is **mitosis**? | | +-----------------------------------+-----------------------------------+ | What is cytokinesis? | | +-----------------------------------+-----------------------------------+ | Mitosis | | +-----------------------------------+-----------------------------------+ | What are the four phases of | | | mitosis? | | +-----------------------------------+-----------------------------------+ | Describe what happens during | | | **prophase**. | | | | | | Include a picture. | | +-----------------------------------+-----------------------------------+ | What are **centrioles**? | | +-----------------------------------+-----------------------------------+ | Describe what happens during | | | **metaphase**. | | | | | | Include a picture. | | +-----------------------------------+-----------------------------------+ | What are **centromeres**? | | +-----------------------------------+-----------------------------------+ | Describe what happens during | | | **anaphase**. | | | | | | Include a picture. | | +-----------------------------------+-----------------------------------+ | What are sister **chromatids**? | | +-----------------------------------+-----------------------------------+ | Describe what happens during | | | **telophase**. | | | | | | Include a picture. | | +-----------------------------------+-----------------------------------+ | Describe what happens during | | | **cytokinesis**. | | | | | | Include a picture. | | +-----------------------------------+-----------------------------------+ | Explain cytokinesis in animal | | | cells. | | +-----------------------------------+-----------------------------------+ | Explain cytokinesis in plant | | | cells. | | +-----------------------------------+-----------------------------------+ **Sample Questions:** 1. Sister chromatids are attached to each other at an area called the a. centriole. b. centromere. c. spindle. d. chromosome. 2. If a cell has 12 chromosomes, how many chromosomes will each of its daughter cells have after mitosis and cytokinesis? e. 4 f. 6 g. 12 h. 24 3. In plant cells, what forms midway between the divided nuclei during cytokinesis? i. nuclear membrane j. centromere k. cell membrane l. cell plate
