Cell Reproduction
Mitosis and Meiosis
| Question | Answer |
|---|---|
| Mitosis is the replication of what kind of cells? | Body cells - from head to toe |
| Meiosis is the replication of what kind of cells? | Sex cells - egg and sperm |
| The number of chromosomes in mitosis will ________ | Stay the same - in a human 46 to 46 or 23 pairs. |
| The number of chromosomes in meiosis will ______ | Cut in half. In a human, 46 goes down to 23 |
| A great way to remember the phases of mitosis is the saying - | I-PMAT - C |
| Before mitosis takes place, chromosomes need to double. This is the longest phase since so many codes need to be copied over. This phase is called - | Interphase |
| In this phase of mitosis, centrioles start to become excited, chromosomes PAIR up. Spindles start to be made and the cell membrane starts to break down. | Prophase |
| In this phase of mitosis, centrioles are on opposite sides of the cell. Spindles are attached to the chromosomes. Chromosomes are lined up in the MIDDLE. Nucleus is gone. | Metaphase |
| In this phase of mitosis, chromosomes are ripped into two. The spindles pull so hard that chromosomes are separated. | Anaphase |
| In this phase of mitosis, TWO new nuclei are created. The number of chromosomes are exactly the same as the original cell! YAYYYYYY | Telophase |
| This is when the cytoplasm pinches and makes two completely new daughter cells. | Cytokenesis |
| In a plant cell, golgi bodies send gooo to the middle to make a new cell wall. This new cell wall is called a - | Cell Plate |
| The reason that meiosis cuts the number of chromosomes in half is because - | 23 from the egg, and 23 from the sperm makes 46! Perfect number for a human. |
| When I am graphing independent and dependent variables, ______ would go on the X axis, and _________ would go on the Y axis? | IV on the X DV on the Y` |
| What is missing - Organism - Organ systems - ____________ - Tissues - Cells | Organs |
