Multiple organs that work together to perform a specific function.
What is an organ system?
100
The first and longest phase of mitosis where chromatin coils into visible chromosomes.
What is prophase?
100
Final phase of mitosis during which new cells prepare for their own independent existence.
What is telophase?
200
Short second phase of mitosis where doubled chromosomes move to the equator of the spindle and chromatids are attached by centromeres to a separate spindle fiber.
What is metaphase?
200
Third phase of mitosis in which the centromeres split and the chromatid pairs of each chromosome are pulled apart by microtubules.
What is anaphase?
200
The process by which two daughter cells are formed.
What is mitosis?
200
The phase of the cell cycle during which the cell grows in size and carries out metabolism.
What is interphase?
300
Groups of cells that work together to perform a specific function.
What is tissue?
300
Group of two or more tissues organized to perform complex activities within an organism.
What are organs?
300
Long strands of DNA wrapped around proteins called histones.
What are chromosomes or chromatin?
300
Cell process following meiosis or mitosis in which the cell's cytoplasm divides and separates into new cells.
What is cytokinesis?
400
Cell structures composed of microtubule fibers; forms between the centrioles during prophase and shorten during anaphase, pulling apart the sister chromatids.
What are spindle fibers?
400
Identical halves of a duplicated parent chromosome formed during the prophase stage of mitosis; the halves are held together by a centromere.
What are sister chromatids?
400
Cell structure that joins two sister chromatids of a chromosome.
What is a centromere?
400
In animal cells, a pair of small cylindrical structures composed of microtubules that duplicate during interphase and move to opposite ends of the cell during prophase.
What are centrioles?
500
Cell structures that carry the genetic material that is copied and pass from generation to generation of cells.
