Sexual & Asexual Reproduction
| Question | Answer |
|---|---|
| The series of events that cells go through to grow and divide is known as the _______. | Cell Cycle. |
| Cell division is when a cell ___. | Divides itself. |
| The cell division of prokaryotic cells is known as ___. | Binary fission. |
| Before a cell divides it has to copy or ___ its DNA. | Replicate. |
| What is asexual reproduction? | Reproduction where there is a single parent that has genetically identical offspring. |
| The cell division that eukaryotic cells go through is known as ____. | Mitosis. |
| Before a cell divides it goes through a long period of growth known as ___. | Interphase. |
| Mitosis has four phases, so what are the names of those phases? | Prophase, metaphase, anaphase, and telophase. |
| What happens during prophase? | The DNA turn to chromosomes, nuclear envelope disappears, and a pair of centrioles start to form. |
| What happens during metaphase? | Chromosomes line up in the middle of the cell, and the spindle fibers from the centrioles connect to them. |
| What happens during anaphase? | The spindle breaks the chromosomes and moves them to opposite sides of the cell. |
| What happens during telophase? | The nuclear envelope starts to form again, the spindle breaks apart, and the cytoplasm starts to divide. |
| After the cell goes through mitosis it goes through a process to divide its cytoplasm, which is known as __. | Cytokinesis. |
| What are the names of the three phases of interphase? | G1, S, and G2. |
| What does mitosis produce? | Mitosis produces two genetically identical cells. |
| For cytokinesis in plants to work a ___ is used to divide the cell. | Cell plate. |
| What is sexual reproduction? | A process in which to different cells unite to make a new organism. |
| During sexual reproduction to cells unite in a process known as ___. | Meiosis. |
| How many cell divisions does a cell go in meiosis. | Two. |
| What is meiosis. | The process in which a cell with two sets of chromosomes (diploid cell) is divided to four cells with one set of chromosomes (haploid cells). |
| What does meiosis produce? | A diploid cell is divided to four haploid cells with half the DNA of the diploid cell and that are genetically different. |
| What are gametes? | Sex cells. |
| What are the two sex cells that join during meiosis? | Egg and sperm cells. |
| When egg and sperm cells join they make a ___. | Zygote. |
| What are the differences between meiosis and mitosis? | Meiosis is more complex and there is more genetic diversity in it than mitosis, but mitosis happens a lot faster than meiosis. |
