Biology cell cycle

TermDefinition
Mitosis A type of cell division that results in 2 identical daughter cells
Meiosis The process by which the nucleus divides in all sexually reproducing organisms
Daughter Cell One of the 2 cells formed from a cell that has undergone cell division, genitally identical to parent cell because they contain the same number and type of chromosomes
Chromatin Nucleic acids and proteins , which condense to form a chromosome during cell division
Chromatid 2 threadlike strands into which chromosomes divide during cell division
Sister Chromatids Pieces of identical copies of single replicated chromosome that are connected by a centromere
Chromosomes A threadlike structure of nucleic acid and protein found in the nucleus, carries genetic information
Homolougous Chromosomes Chromosome pairs, from each parent, similar gene position
Gene A unit of heredity passed from parent to child
Karyotype The number and visual appearance in the chromosomes in the cell nuclei
Centrioles Cylindrical organelles, involved in the developement of fiber spindles
Centromere The point at which the two chromatids forming the chromosome are joined together
Centrosome an organelle that serves as the main microtubule organizing center of the cell
Aster Star shaped structure formed during division of the nucleus in an animal cell
Spindle Fibers Form a protein structure that divides the genetic material material in a cell
Kinetochore Fiber Microtubules that connect kinetochores to spindle polar fibers
Nucleolus The round structure within the nucleus of a cell, and composed of protein and RNA
Nuclear Envelope The double layered membrane enclosing the nucleus of a eukaryotic cell
Interphase Phase with G1, S, and G2, where cell grows and prepares for cell division
Prophase First phase of mitosis, nuclear envelope breaks down, spindle fibers form
Metaphase Second phase of mitosis, duplicated chromosomes line up
Anaphase Chromosomes move away from each other to opposite poles of the spindle fibers
Telophase Final phase in mitosis, the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes
Cytokinesis Physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells

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.

To see how well you know the information, try the Quiz or Test activity.
