Chapter 8

Question 1

Centromere

Answer 1

Cell structure that joins to sister chromatids to the chromosomes

Question 2

Telophase

Answer 2

Final phase of mitosis during which a new cells prepare for their own independent existence

Question 3

Spindle

Answer 3

Cell structures composed of microtubule fibers

Question 4

Metaphase

Answer 4

Short second phase of mitosis where double chromosomes move to the equator of the spindle and chromatids are attached by chromatin separate spindle fibers

Question 5

Organ

Answer 5

Group of two or more tissues organized to perform complex activities within an organism

Question 6

Gene

Answer 6

Segment of DNA that controls the protein production in the cell cycle

Question 7

Anaphase

Answer 7

Phase of mitosis where the chromosomes split and the chromatid pairs of each chromosomes are pulled apart by microtubules

Question 8

Organ system

Answer 8

Multiple organs that work together to perform a specific life function

Question 9

Osmosis

Answer 9

Diffusion of water across a selectively permeable membrane

Question 10

Passive transport

Answer 10

Movement of particles across cell membranes by diffusion or osmosis

Question 11

Exocytosis

Answer 11

Active transport process by which materials are secreted or spelled from a cell

Question 12

Interphase

Answer 12

Cell growth phase where difference in size, carries for metabolism, and duplicates chromosomes prior to division

Question 13

cancer

Answer 13

Uncontrollable cell division

That might be caused by environmental factors and or change in enzyme production in the cell cycle
