9th gr cell division
| Question | Answer |
|---|---|
| The sister chromatids are moving apart | Anaphase |
| The nucleus begins to fade from view | Prophase |
| A new nuclear membrane is forming around the chromosomes | Telophase |
| The cytoplasm of the cell is being divided | Cytokinesis |
| The chromosomes become visible | Prophase |
| The chromosomes are located at the equator of the cell | Metaphase |
| The nuclear membranes begin to fade from view | Prophase |
| The division (cleavage) furrow divides the animal cell | Cytokinesis |
| The chromosomes are moving towards the poles of the cell | Anaphase |
| Chromatids at the middle of the cell are attached to spindle fibers | Metaphase |
| The spindle is formed | Prophase |
| Chromosomes are not visible | Interphase |
| Cytokinesis is completed | Cytokinesis |
| The cell plate forms new cell membranes and walls | Cytokinesis |
| DNA is replicated | Interphase |

| What is the name of the structure that connects the two chromatids | Centromere |
| what is each individual copy of DNA called? (long thin strands of DNA) | Chromatid |
| What are the two stages of cell division? | Mitosis and cytokinesis |
| What structure forms Intprophase along which the chromosomes move? | Spindle fibers |
| Which phase of mitosis is the last phase that chromatids are together? | Metaphase |
| Which stage of the cell cycle is characterized by a non dividing cell. | Interphase |
| What structure is produced when protein fibers radiated from the centrioles | Centromere |
| What forms across the center of a plant cell near the end of telophase | Cell plate |
| The period of cell growth and development between mitotic division | Interphase |
| What are the three stages of the cell cycle in order? | Interphase, mitosis, cytokinesis |
| What are the four phases of mitosis in order | Prophase, metaphase, anaphase, telophase |

| What is the process of programmed cell death | Apoptosis |
| What is uncontrolled cell growth | Cancer |
| What is difference between benign tumor and malignant tumor | Benign- non cancerous/. Malignant - cancerous |
| Explain the difference in sexual and asexual reproduction, name several types of asexual reproduction | Sexual - combination of both parents Asexual- identical to parent Types of asexual- budding, regeneration, binary fission |
