Asexual reproduction Process of reproduction involving a single parent that results that are genetically identical to the parents
Apoptosis Process of programed cell death
Anaphase Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
Blastocyst Stage of early development in mammals that consist of a hollow ball of cells
Cell division Process by which a cell divides into 2 new daughter cells
Chromosome Threadlike structure of DNA and protein that contains genetic information; in eukaryotes, chromosomes are found in the nucleus; in prokaryotes they are found the cytoplasm
Chromatin Substance found in eukaryotic chromosomes that consists of 2DNA tightly coiled around histones
Cell cycle Series of events in which a cell grows, prepares for division, and divides to form 2 daughter cells
Cytokinesis Division of the cytoplasm to form 2 separate daughter cells
Cancer Disorder in which some of the bodies cells lose the ability to control growth
Cyclin One of a family of proteins that regulates the cell cycle in eukaryotic cells
Centromere Region of a chromosome where the 2 sister chromosomes attach
Centriole Structure in an animal cell that helps to organize cell division
Differentiation Process in which cells become more specialized in structure and function
Interphase Period of the cell cycle between cell divisions
Metaphase Phase of mitosis in which the chromosomes line up across the center of the cell

Telophase Phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
Growth factor One of a group of external regulatory proteins that stimulate the growth and division of cells
Pluripotent Cells that are capable of developing into most, but not all, of the bodies cell types
Stem Cell Unspecialized cell thar can give rise to one or more types of specialized cells
Multipotent Cells with limited potential to grow into many types of differentiated cells.
Sexual reproduction Type of reproduction in which the cells from 2 parents unite to form the first cell of a new organism

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.
