|---|---|---|---|---|---|
| Mitosis | A type of cell division that results in two daughter cells.
🗑
|
||||
| Cytokinesis | The cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
🗑
|
||||
| Replication | The action of copying or reproducing something.
🗑
|
||||
| Cell Cycle | The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA
🗑
|
||||
| Chromosomes | Chromosomes are the things that make organisms what they are. They carry all of the information used to help a cell grow, thrive, and reproduce
🗑
|
||||
| Chromatid | Each of the two threadlike strands into which a chromosome divides longitudinally during cell division
🗑
|
||||
| Centromere | The point on a chromosome by which it is attached to a spindle fiber during cell division.
🗑
|
||||
| Chromatin | The material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA
🗑
|
||||
| Diploid | Containing two complete sets of chromosomes, one from each parent.
🗑
|
||||
| Interphase | the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
🗑
|
||||
| Crossing over | the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring.
🗑
|
||||
| Tetrad | a group or set of four.
🗑
|
||||
| Synapsis | the fusion of chromosome pairs at the start of meiosis.
🗑
|
||||
| Polar bodies | each of the small cells that bud off from an oocyte at the two meiotic divisions and do not develop into ova.
🗑
|
||||
| Gametogenesis | the process in which cells undergo meiosis to form gametes.
🗑
|
||||
| Gonad | an organ that produces gametes; a testis or ovary.
🗑
|
||||
| Gamete | a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
🗑
|
||||
| Ovum/ ova | a mature female reproductive cell, especially of a human or other animal, that can divide to give rise to an embryo usually only after fertilization by a male cell.
🗑
|
||||
| Sperm | the mature motile male sex cell of an animal, by which the ovum is fertilized, typically having a compact head and one or more long flagella for swimming.
🗑
|
||||
| Haploid | having a single set of unpaired chromosomes.
🗑

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.
