nucleolus

Question 4

Form cilia and flagella; critical to cell division for the separation of chromosomes

Answer 4

centrioles

Question 5

Production of ATP via cellular respiration

Answer 5

mitochondria

Question 6

Answer 6

smooth er

Question 7

Site of protein synthesis

Answer 7

ribosome

Question 8

Answer 8

rough er

Question 9

Storage, processing, modification, and packaging of proteins to be exported from the cell, embedded in the plasma membrane, or included in lysosomes

Answer 9

Golgi aparatus

Question 10

Contains digestive enzymes that break down damaged organelles or substances that the cell engulfs

Answer 10

lysosome

Question 11

Maintains cell shape and allows cell movement

Answer 11

cytoskeleton

Question 12

Structure found only on sperm cells that allows for cell motility

Answer 12

flagella

Question 13

Short, hair-like projections of the cell that move substances along the cell’s surface

Answer 13

cilia

Question 14

Cell is not actively dividing; normal metabolic activities are performed; DNA replicates during this phase, but chromosomes are not visible

Answer 14

interphase

Question 15

A series of steps resulting in division of the nucleus

Answer 15

mitosis

Question 16

Nuclear membrane disappears; chromatin condenses into visible chromosomes; centrioles move to opposite poles of the cell

Answer 16

prophase

Question 17

Chromosomes line up at the middle of the cell; spindle fibers attach to centrosomes of chromatids

Answer 17

metaphase

Question 18

Chromatids move to opposite poles of the cell

Answer 18

anaphase

Question 19

Nuclear membrane reforms; chromosomes uncoil

Answer 19

telophase

Question 20

The cytoplasm divides creating two new daughter cells

Answer 20

cytokinesis

Question 21

requires energy (ATP) and moves substances from areas of low concentration to high concentration.

Answer 21

active transport

Question 22

does not require energy (ATP) and moves substances from areas of high concentration to low concentration.

Answer 22

passive transport
