Chapter 3 Cells

Question 1

Telophase

Answer 1

the nuclear envelopes will form around each nucleus and the nucleoli will reappear.

Question 2

Metaphase

Answer 2

Condensed and highly coiled chromosomes move to a central zone

Question 3

prophase

Answer 3

during this phase, chromatin condenses into two identical copies of each chromosome

Question 4

anaphase

Answer 4

chromosomes begin to pull toward opposite ends

Question 5

cytokinesis

Answer 5

the cytoplasm of a single cell divides to form two daughter cells.

Question 6

cytology

Answer 6

The study of the structure and function of cells

Question 7

centrioles

Answer 7

are involved in the organization of the mitotic spindle during cell division

Question 8

ribosomes

Answer 8

organelles are responsible for protein synthesis. they are composed of a large and a small ribosomal subunit.

Question 9

S.E.R. (Smooth Endoplasmic Reticulum)

Answer 9

synthesizes lipids, phospholipids, and steroids. These do not contain ribosomes

Question 10

Lysosomes

Answer 10

is a spherical vesicle membrane-bound cell organelle containing hydrolytic enzymes

Question 11

Peroxisomes

Answer 11

small spherical vesicle membrane-bound cell organelle containing oxidative enzymes

Question 12

Apoptosis

Answer 12

describes the genetically controlled death of cells. Also induced by errors during mitosis

Question 13

An RBC in a hypertonic solution will cause the cell to ___

Answer 13

Crenate (shrink)

Question 14

An RBC in a hypotonic solution will cause the cell to ____

Answer 14

Hemolyze (swell)

Question 15

An RBC in an isotonic solution will cause the cell to ____

Answer 15

not change its shape

Question 16

These form a virtually impermeable barrier to fluids.

Answer 16

Tight junctions

Question 17

These allow molecules, ions, and electrical impulses to pass through these regulated gates between two cells

Answer 17

Gap junctions

Question 18

These allow molecules, i

Question 19

True or False? The rough ER is a network of membranes with attached ribosomes.

Answer 19

True

The phase can be perceived as a moment in time in which the cell is neither dividing nor preparing to divide.

Answer 20

G0

Question 21

DNA is replicated during this phase.

Answer 21

Question 22

During this phase, the cell growls in size and synthesizes mRNA

Answer 22

G1

Question 23

The phase directly precedes mitosis

Answer 23

G2

Question 24

During this phase, the cell divides into two identical cells

Answer 24

M phase
