Asexual Reproduction

Biology

TermDefinition
asexual reproduction a method of reproduction in which all the genes passed on to the offspring come from a single individual or parent
autosome chromosome that is not a sex chromosome
chromosome a thick, threadlike structure that contains genetic information in the form of DNA
cell plate A disc like structure in the plane of the equator of the spindle that separates the two sets of chromosomes during cytokinesis; also involved in the formation of cell wall between the two daughter cells following cell division.
cytokinesis division of the cytoplasm to form two separate daughter cells
cancer disorder in which some of the body's cells lose the ability to control growth
chromatid one of two identical "sister" parts of a duplicated chromosome
chromatin substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
cell cycle series of events in which a cell grows, prepares for division, and divides to form two daughter cells
diploid term used to refer to a cell that contains two sets of homologous chromosomes
gamete an egg or sperm cell; a sex cell
gene a segment of DNA (on a chromosome) that contains the code for a specific trait
haploid term used to refer to a cell that contains only a single set of genes
homologous term used to refer to chromosomes in which one set comes from the male parent and one set comes from the female parent
karyotype micrograph of the complete diploid set of chromosomes grouped together in pairs, arranged in order of decreasing size
sexual reproduction a method of reproduction that involves two parents to produce offspring that are genetically different from either parent
spindle A collection of minute fibers composed of microtubules, which are prominent during cell division, as mitotic spindle or mitotic apparatus''.
zygote the cell that results from the joining of the egg and the sperm
centrioles structure in an animal cell that helps to organize cell division
interphase period of the cell cycle between cell divisions
prophase first and longest phase of mitosis in which the genetic material inside the nucleus condenses and the chromosomes become visible
metaphase phase of mitosis in which the chromosomes line up across the center of the cell
anaphase phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
telophase phase of mitosis in which the distinct individual chromosomes begin to spread out into a tangle of chromatin
binary fission type of asexual reproduction in which an organism replicates its DNA and divides in half, producing two identical daughter cells
budding The formation of an outgrowth from an organism, and is capable of developing into a new individual; gemmation.
regeneration the natural renewal of a structure, as of a lost tissue or a part
vegetative propogation method of asexual reproduction in plants, which enables a single plant to produce offspring that are genetically identical to itself
mitosis the process that divides the cell's nucleus into two, each with a complete set of genetic material from the parent cell

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.
