|---|---|---|---|---|---|
| Cell Cycle | The sequence of events that occurs in a cell between divisions
🗑
|
||||
| Chromatin | Long thin strands of DNA found in the nucleus
🗑
|
||||
| Chromosomes | The duplicated strands of chromatin that happens during Interphase
🗑
|
||||
| Chromatids | The thickened coiled up chromosomes in Prophase & Metaphase
🗑
|
||||
| Centromere | The point where the chromosomes and chromatids connect
🗑
|
||||
| Interphase | Part One of the Cell Cycle. DNA & chromosomes are duplicated; growth occurs; organelles are duplicated.
🗑
|
||||
| Mitosis | Part Two of the Cell Cycle; division of the nucleus occurs.
🗑
|
||||
| Prophase | First step of mitosis; chromosomes coil & thicken & become chromatids; centrioles migrate to the poles of the cell.
🗑
|
||||
| Metaphase | Second step of mitosis; chromatids line up on the equator; spindle fibers attach to the centromeres of the chromatids
🗑
|
||||
| Anaphase | Third step of mitosis; centromeres separate; chromatids pull apart and become chromosomes
🗑
|
||||
| Telophase | Fourth step of mitosis: two new nuclear membranes form at the poles; cytoplasm begins to divide
🗑
|
||||
| Cytokinesis | Third part of the Cell Cycle; cytoplasm divides; animals form a protein belt; plants form a cell plate
🗑
|
||||
| Centrioles | A barrel-shaped structures in animal cells that play a role in mitosis
🗑
|
||||
| Diploid cells | Body cells that have pairs of chromosomes.
🗑
|
||||
| Haploid cells | The sex cells that have a single set of chromosomes.
🗑
|
||||
| Zygote | The cell created by fertilization.
🗑
|
||||
| Meiosis | The process that halves the number of chromosomes and creates the sex cells.
🗑
|
||||
| Asexual reproduction | A process which produces a new organism from a single parent; offspring are identical to the parent.
🗑
|
||||
| Regeneration | Aprocess that re-grows lost or damaged body parts
🗑
|
||||
| Budding | A new organism growing from the body of the parent
🗑
|
||||
| Binary fission | Reproduction that occurs in prokaryotic cells; the DNA duplicates, then the cell splits.
🗑
|
||||
| Sexual reproduction | A process where two organisms come together to produce a new organism that is genetically different.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
