Sister chromatid

Identical halves of a parent chromosome

1

Centromere

structure that joins two sister chromatids

2

Centriole

A pair of small structures composed of micro tubules that duplicate during interphase and move to opposite ends of the cell during prophase

3

Spindles

Cell structures composed of fibers; forms between the centrioles and pull apart sister chromatids

4

Tissue

Groups of cells that work together to perform a specific function

5

Organ

Group of two or more tissues

6

Organ system

Multiple organs that work together to perform a specific life function

7

Sexual reproduction

Pattern of reproduction that involves the production of and subsequent fusion of haploid sex cells

8

Genetic recombination

Major source of genetic variation among organisms caused by crossing over

9

Nondisjunction

Failure of homologous chromosomes to separate properly during meiosis

10

Chromatin

strands of DNA found in the nucleus; form chromosomes
