Science Vocab Words

Front 1

Anaphase

Back 1

The stage of mitosis or meiosis beginning with the separation of sister chromatids (or homologous chromosomes) followed by their movement towards the poles of the spindle.

Front 2

Asexual reproduction

Back 2

A form of reproduction that does not involve meiosis, ploidy reduction or fertilization, and the offspring is a clone of the parent organism; because of no exchange of genetic material.

Front 3

Binary fission

Back 3

A type of asexual reproduction common among prokaryotes wherein a cell divides giving rise to two cells, each having the potential to grow to the size of the original cell.

Front 4

chromosome

Back 4

structure within the cell that bears the genetic material

Front 5

cytokinesis

Back 5

The division of the cytoplasm and the plasma membrane following the division of the nucleusresulting into two cells, each having its own nucleusand cytoplasm surrounded by a plasma membrane.

Front 6

interphase

Back 6

The phase in the life cycle of a cell wherein the cell is not undergoing cell division

Front 7

Meiosis

Back 7

A form of cell division happening in sexually reproducing organisms by which two consecutive nuclear divisions occur without the chromosomal replication in between, leading to the production of four haploid gametes (sex cells), each containing one of every pair of homologous chromosomes .

Front 8

Metaphase

Back 8

The stage of mitosis (and meiosis) following prophase and preceding anaphase. At this stage, the condensed chromosomes have aligned along the metaphase (or equatorial) plate, an imaginary plane located between the poles of a dividing cell, while the microtubules formed during prophase would then attach themselves to kinetochores.

Front 9

Mitosis

Back 9

The process where a single cell divides resulting in generally two identical cells, each containing the same number of chromosomes and genetic content as that of the original cell.

Front 10

Prophase

Back 10

The first phase of cell divisions (i.e. mitosis and meiosis), and in which during this phase the chromatin condenses (becoming more visible under a light microscope at high magnification) and initiating spindle formation

Front 11

sexual reproduction

Back 11

A mode of reproduction involving the fusion of female gamete (ovum) and male gamete (spermatozoon), which forms a zygote that potentially develops into genetically distinct offspring.

Front 12

sister chromatids

Back 12

Two identical strands joined by a common centromere as a result of a chromosome that duplicated during the S phase of the cell cycle.

Front 13

telophase

Back 13

The final stage of mitosis or meiosis, when chromosome separation is completed. The final stage of mitosis.The final stage of meiosis when the chromosomes move toward opposite ends of the nuclear spindle.A stage of nuclear Division in meiosis and mitosis, occurring once in mitosis and twice in meiosis.
