Cells and Cell Cycle

Question 1

Principle Components of Cells

Answer 1

Cell Membrane/Plasma
Cell Wall
Cytoplasm
Cytoskeleton

Question 2

Nucleus

Answer 2

Largest oranelle that contains the nucleolus and chromatine. Regulates cellular processes

Question 3

Chromatin

Answer 3

Strand of nearly equal amounts of DNA and globular histone proteins. Loose and diffused chromosomes

Question 4

Nucleolus

Answer 4

Spherical body in nucleus that is fundamental to the growth rate of the cell

Question 5

Somatic Cells

Answer 5

Human cells that make up organs, tissues, structures, etc. that contain 2 sets of 23 chromosomes and proliferate by mitosis

Question 6

Germ Cells

Answer 6

Human cells associated with reproduction that contain 1 set of 23 chromosomes

Question 7

Interphase

Answer 7

Total period from cell formation to cell division of the Cell Cycle where the cell grows and carries on its normal activities

Question 8

Mitosis

Answer 8

Period of the Cell Cycle where the cell reproduces

Question 9

4 Stages of the Cell Cycle

Answer 9

G1: Active growth and metabolism

S: DNA synthesis and duplication

G2: Synthesis of molecules in preparation for cell division

M: Mitosis

Question 10

G1 Phase

Answer 10

Sub-phase of interphase where the cell synthesizes proteins & grow vigorously

Question 11

S phase

Answer 11

Sub-phase of interphase where DNA replicates

Question 12

G2 Phase

Answer 12

Sub-phase of interphase where enzymes/proteins needed for division are synthesized and moved to their proper sites

Question 13

Sub-phases of Mitosis

Answer 13

Prophase

Metaphase

Anaphase

Telophase/cytokinesis

Question 14

Meiosis

Answer 14

Process by which germ cells divide
No DNA replication
Daughter cells only have 1/2 the genetic material of the parent cell
