Stephen Fyler 8.2

the membrane=bound structures within eukaryotic cells
Stephen Fyler 8.2

organelle
Stephen Fyler 8.2

cell structures that carry the genetic material that is copied and passed from generation to generation of cells
Stephen Fyler 8.2

chromosome
Stephen Fyler 8.2

long strands of DNA wrapped around proteins called histones
Stephen Fyler 8.2

chromatin
Stephen Fyler 8.2

the sequence of growth and division of a cell
Stephen Fyler 8.2

cell cycle
Stephen Fyler 8.2

a cell grows in size and carries on metabolism; the majority of a cell's life is spent in this growth period
Stephen Fyler 8.2

interphase
Stephen Fyler 8.2

the process by which two daughter cells are formed, each containing a complete set of chromosomes
Stephen Fyler 8.2

mitosis
Stephen Fyler 8.2

the long, stringy chomatin coils up into visible chromosomes; the first and longest phase of mitosis
Stephen Fyler 8.2

prophase
Stephen Fyler 8.2

the two halves of the doubled structure in the chromosome
Stephen Fyler 8.2

sister chromatid
Stephen Fyler 8.2

this structure holds together sister chromatids
Stephen Fyler 8.2

centromere
Stephen Fyler 8.2

small, dark, cylindrical structures that are made of microtubules and are located just outside the nucleus
Stephen Fyler 8.2

centriole
Stephen Fyler 8.2

a football-shaped, cagelike structure consisting of thin fibers made of microtubules
Stephen Fyler 8.2

spindle
Stephen Fyler 8.2

the short second phase of mitosis in which the doubled chromosomes become attached to the spindle fibers by their centromeres
Stephen Fyler 8.2

metaphase
Stephen Fyler 8.2

the third phase of mitosis in which the centromeres split apart and chromatid pairs from each chromosome separate from each other
Stephen Fyler 8.2

anaphase
Stephen Fyler 8.2

the final phase of mitosis in which begins as the chromatids reach the opposite poles of the cell
Stephen Fyler 8.2

telophase
Stephen Fyler 8.2

the cell process following mitosis in which the cell's cytoplasm divides and separates into new cells
Stephen Fyler 8.2

cytokinesis
Stephen Fyler 8.2

groups of cells that work together to perform a specific function
Stephen Fyler 8.2

tissue
Stephen Fyler 8.2

group of two mor more tissues organized to perform complex activities within an organism
Stephen Fyler 8.2

organ
Stephen Fyler 8.2

multiple organs that work together to perform a specific life function
Stephen Fyler 8.2

organ system
Stephen Fyler 8.3

a large complex polymer composed of carbon, hyrdrogen, oxygen, nitrogen, and sometimes sulfur
Stephen Fyler 8.3

protein
Stephen Fyler 8.3

a malignant growth resulting from uncontrolled cell division
Stephen Fyler 8.3

cancer
Stephen Fyler 8.3

a segment of DNA that controls the produciton of a protein
Stephen Fyler 8.3

gene
