Q

Phase and what’s happening

A

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

Nucleus

A

Contains chromatin and nucleolus

34
Q

Nucleolus

A

Assembles ribosomes

35
Q

Chromatin (chromosomes in cell division)

A

Location of DNA (genes); provides genetic regulation of the cell

36
Q

Nuclear membrane

A

Double layer of membrane; outer boundary of nucleus

37
Q

Nuclear pore

A

Allows maaterial to move between cytoplasm and nucleoplasm

38
Q

Cell membrane/plasma membrane

A

Regulates passage of materials into/out of the cell (selectively permeable)

39
Q

Rough Endoplasmic Reticulum

A

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

40
Q

Smooth Endoplasmic Reticulum

A

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

41
Q

Ribosome

A

Site of protein synthesis

42
Q

Centriole/centrosome

A

Produce systems of microtubules like cytoskeleton and spindle apparatus

43
Q

Golgi body (golgi apparatus)

A

Synthesis (final assembly of complex molecules), short term storage, transport & packaging of materials - especially for secretion

44
Q

Secretory vesicles

A

Export materials via exocytosis

45
Q

Lysosome

A

Intracellular digestion of large organic molecules into their simpler components

46
Q

Peroxisome

A

Detoxify harmful metabolic toxins like alcohols and hydrogen peroxide

47
Q

Mitochondrion

A

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

48
Q

Cytosol (cytoplasm)

A

Numerous metabolic reactions and maintains spatial relationships in the cell

49
Q

Stages of the Mitotic Cell Cycle

A

Interphase, Prophase, Metaphase, Anaphase, Telophase

50
Q

Interphase

A

General cell growth and DNA replication

51
Q

Prophase

A

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

52
Q

Metaphase

A

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

53
Q

Anaphase

A

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

54
Q

Telophase

A

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
