Section 5.1 and 5.2

Cell Increase and Decrease, Maintaining the Chromosome Number

VocabDefinition
somatic cells body cells
mitosis division of the nucleus during cell division
cytokinesis division of the cytoplasm during cell division
apotosis programmed cell death
cell cycle an orderly set of stages that take place between the time a cell divides and the time the resulting cell also divides
interphase stages of the cell cycle (G1, S, G2) during which growth and DNA synthesis occur when the nucleus is not actively dividing
cyclin protein that ccles in quantity as the cell cycle progresses; combines with and activates the kinases theat function to promote the events of the cell cycle
chromatin network of fibrils consisting of DNA and associated proteins observed within a nucleus that is not dividing
chromosomes rodlike structure in the nucleus seen during cell division; contains the hereditary units, or genes
dipliod (2n) number twice the number of chromosomes found in the gametes
haploid (n) number half the diploid number. contains one of each kind of chromosome
duplicated chromosome composed of two sister chromatids held together in the centromere
centromere constricted region of a chromosome where sister chromatids are attached to one another and where the chromosome attaches to a spindle fiber
sister chromatid one of two genetically identical chromosomal units that are the result of DNA replication and are attached to each other at the centromere
daughter chromosomes the centromeres divide and then the sister chromatids separate and become these.
spindle microtubule structure that brings about chromosomal movement during nuclear division
centrioles cell organelle, existing in pairs, tht occurs in the centrosome and may help organize a mitotic spindle for chromosome mvement during animal cell division
aster short, radiating fiber produced by the centrosomes in animal cells
prophase mitotic phase during which chromatin condenses so that chromosomes appear; chromosomes are scattered
metaphase mitotic phase during which chromosomes are aligned at the metaphase plate
metaphase plate a plane perpendicular to the axis of the spindle and equidistant from the poles
anaphase mitotic phase during which daughter chromosomes move toward the poles of the spindle
telophase mitotic phase during which daughter cells are located at each pole
cleavage furrow an indentation of the membrane between the two daughter nuclei (animal cells)
cell plate structure that precedes the formation of the cell wall as a part of cytokinesis in plant life

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.
