TermDefinition
Mitosis is the process in which a eukaryotic cell nucleus splits in two, followed by division of the parent cell into two daughter cells.
Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.
Replication DNA replication or DNA synthesis, the process of copying a double-stranded DNA molecule.
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 (DNA replication) to produce two daughter cells.
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells.
Chromatid is one copy of a newly copied chromosome which is still joined to the other copy by a single centromere.
Centromere is the part of a chromosome that links sister chromatids or a dyad.
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells.
Diploid containing two complete sets of chromosomes, one from each parent.
Interphase is the phase of the cell cycle in which a typical cell spends most of its life.
Crossing over is the exchange of genetic material between homologous chromosomes that results in recombinant chromosomes during sexual reproduction.
Tetrad A group or set of four. A tetravalent atom, radical, or element
Synapsis is the pairing of two homologous chromosomes that occurs during meiosis.
Polar bodies is a small haploid cell that is formed concomitantly as an egg cell during oogenesis, but which generally does not have the ability to be fertilized.
Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid 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 is the male reproductive cell.
Haploid is the term used when a cell has half the usual number of chromosomes.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
