Biology 10

oh yeah

TermDefinition
cell division process in which a cell divides into two daughter cells
asexual reproduction process of reproduction that results in one parent having offspring that are genetically identical to the parent
sexual reproduction type of reproduction in which cells from two parents unite to form the first cell of a new organism
chromosome DNA and protein that contains genetic information
centromere region of the chromosome where the two sister chromatids attach
chromatin substance found in eukaryotic cells that consist of DNA tightly coiled around histones
chromatid each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.
cell cycle the growth cycle of a cell
centriole a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
interphase the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
metaphase the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.
mitosis a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
anaphase the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.
cytokinesis the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
telophase phase of mitosis the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
cyclin any of a number of proteins associated with the cycle of cell division which are thought to initiate certain processes of mitosis.
cancer Uncontrolled cell growth that causes tumors
growth factor the factor of growth
tumor a swelling of a part of the body, generally without inflammation, caused by an abnormal growth of tissue, whether benign or malignant.
apoptosis the death of cells which occurs as a normal and controlled part of an organism's growth or development.
embryo an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus).
pluripotent (of an immature or stem cell) capable of giving rise to several different cell types.
differentiation the action or process of differentiating.
stem cell an undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.
totipotent (of an immature or stem cell) capable of giving rise to any cell type or (of a blastomere) a complete embryo.
multipotent a cell that can be converted into another type of cell.
blastocyst a mammalian blastula in which some differentiation of cells has occurred.

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.
