Ch 8 - Cell Growth

Ch 8 Cell Growth and Reproduction

QuestionAnswer
Anaphase The third phase
Apoptosis programmed cell death
Asexual reproduction reproduction using one parent
Autosomes All the other chromosomes in the organism.
Binary Fission The division of a prokaryotic cell into two offspring cells.
Cancer any malignant growth or tumor caused by abnormal and uncontrolled cell division
Cell cycle series of events that cells go through as they grow and divide
Cell division the process in reproduction and growth by which a cell divides to form daughter cells
Cell Plate In a plant cell
Centriole Cell organelle that aids in cell division in animal cells only
centromere The point where two Chromatids are attached.
Chromatid each half of the chromosomes
chromatin Less tightly coiled DNA-protein complex.
chromosomes Rod-shaped structures made of DNA and Protein.
Crossing over Chromotids may break off and connect to adjacent Homologous Chromosomes.
Cyclin one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells
Cytokinesis the division of the cell's cytoplasm
Diploid the set of two chromosomes.
Gametes haploid reproduction cells.
Genetic Recombination when a new mixture of genetic material is created.
Growth factor one of a group of external regulatory proteins that stimulate the growth and division of cells
Haploid one of the chromosomes in the diploid
Histones Maintain the shape of chromosomes and aid in the tight packing of DNA.
Homologous Chromosomes the copy of each autosomes
Independent Assortment The random seperation of the Homologous Chromosomes.
Interphase the time between cell division
Karyotype A photomicrograph of the chromosomes in a normal dividing cell found in a human.
Meiosis Reduces the chromosome count by half in new cells.
Metaphase The second phase of Mitosis
Mitosis Cell division that results in new cells.
Oogenesis the production of mature eggs.
Polar body The other three products of meiosis that eventually degenerate.
Prophase the first phase of mitosis
Sex chromosomes determine the sex of the chromosomes
Sexual reproduction The production of offspring through meiosis and the union of a sperm and an egg cell.
Spermatogensis the production of sperm cells.
Spindle Fibers Radiate from the newly seperated centromeres to prepare for Metaphase.
Synapsis The pairing of Homologous Chromosomes.
Telophase After the chromosome seperates
Tetrad Each pair of Homologous Chromosomes.
Tumor A mass of abnormal cells that develops when cancerous cells divide and grow uncontrollably.

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.
