The Cell

Question 1

Phase and what’s happening

Answer 1

Interphase - a period of general cell growth and DNA replication

Question 2

Phase and what’s happening

Answer 2

Prophase - nuclear membrane disappears, nucleolus disappears, chromatin condenses into chromosomes, spindle apparatus forms

Question 3

Phase and what’s happening

Answer 3

Metaphase - chromosomes line up on metaphase plate

Question 4

Phase and what’s happening

Answer 4

Anaphase - centromere splits to end metaphase/begin anaphase, sister chromatids (now = chromosomes) pulled to opposte poles by spindle apparatus

Question 5

Phase and what’s happening

Answer 5

Telophase/cytokinesis - chromosomes reach opposite poles and clump; events of prophase are reversed; cytokinesis (division of the cell) is completed

Phase and what’s happening

Answer 6

Anaphase - centromere splits to end metaphase/ begin anaphase; sister chromatids (now = chromosomes) pulled to opposite poles by spindle apparatus

Rough Endoplasmic Reticulum

Answer 39

Synthesis of proteins, short term storage, transport (passageway) & packaging of proteins

Question 40

Smooth Endoplasmic Reticulum

Answer 40

Synthesis of steroids and lipids (not proteins), short term storage, transport (passageway) & packaging of carboydrates/lipids; drug detoxification

Question 41

Detoxify harmful metabolic toxins like alcohols and hydrogen peroxide

Question 47

Mitochondrion

Answer 47

Site of aerobic (oxygen requiring) steps of cellular respiration (breakdown glucose to energize ATP)

Question 48

Cytosol (cytoplasm)

Answer 48

Numerous metabolic reactions and maintains spatial relationships in the cell

Question 49

Stages of the Mitotic Cell Cycle

Answer 49

Interphase, Prophase, Metaphase, Anaphase, Telophase

Question 50

Interphase

Answer 50

General cell growth and DNA replication

Question 51

Prophase

Answer 51

Nuclear membrane disappears, nucleolus disappears, chromatin condenses into chromosomes, spindle apparatus forms

Question 52

Metaphase

Answer 52

Chromosomes line up in metaphase plate (centromere splits to end metaphase/begin anaphase)

Question 53

Anaphase

Answer 53

Sister chromatids (now = separate chromosomes) are pulled to the opposite poles by the spindle apparatus

Question 54

Telophase

Answer 54

Chromosomes reach the opposite poles and clump; events of prophase are reversed (chromosomes to chromatin, nucleolus and nuclear membrane reform, spindle apparatus dismantled); cytokinesis is completed
