Cell Division

Question 1

he said that “cells comes from pre-existing cell”

Answer 1

Rudolf Virchow

Question 2

division of cells and its contents into two or more cells

Answer 2

cell division

Question 3

why is it important for cell division to occur?

Answer 3

replace, repair, and reproduce

Question 4

it is the preparatory stage before cell division

Answer 4

interphase

Question 5

rapid growth of newly produced cells
creation of copies of organelles and molecular building blocks

Answer 5

G1 phase (first gap)

Question 6

centrioles replicate
DNA replicates, producing 2 identical chromatids

Answer 6

S phase (synthesis)

Question 7

grows more
makes more proteins and organelles

Answer 7

G2 phase (second gap)

Question 8

reorganization of cell contents

Answer 8

G2 phase (growth gap 2)

Question 9

cell size, nutrients, DNA integrity

Answer 9

G1 Checkpoint

Question 10

DNA integrity, complete DNA replication

Answer 10

G2 Checkpoint

Question 11

ensures that irreparable cells will not divide

Answer 11

apoptosis

Question 12

chromosome alignment and attachment to spindle fibers

Answer 12

M checkpoint or spindle checkpoint

Question 13

a type of cell division in which one parent cell divides to produce two new cells (daughter cells)

Answer 13

mitosis

Question 14

production of 2 daughter cells that has same number of chromosomes
the 2 daughter cells are genetically identical

Answer 14

mitosis

Question 15

produces body cells or somatic cells

Answer 15

mitosis

Question 16

chromosomes start to condense
formation of spindle fiber
nucleolus disappears

Answer 16

early prophase

Question 17

nuclear membrane disappears
spindle fibers bind to chromosomes at the kinetochore

Answer 17

prophase

Question 18

nuclear envelope breaks down
chromosomes fully condensed

Answer 18

late prophase (prometaphase)

Question 19

alignment of chromosomes in the metaphase plate

Answer 19

metaphase

Question 20

spindle fibers shorten and pull the sister chromatids in the opposite poles

Answer 20

anaphase

Question 21

spindle fibers breaks down
nuclear envelope starts to form
chromosomes start to uncoil
nucleolus forms

Answer 21

telophase

Question 22

division of the cytoplasm

Answer 22

cytokinesis

Question 23

cytokinesis in animals can form?

Answer 23

cleavage furrow

Question 24

cytokinesis in plants can form?

Answer 24

cell plate

Question 25

type of cell division involved in the production of gametes

Answer 25

meiosis

Question 26

reproductive/sex/germ cells

Answer 26

gametes

Question 27

contains half number of chromosomes as the normal body cells (haploid)

Answer 27

gametes

Question 28

produces 4 daughter cells that has half the number of chromosomes as the parent cell

Answer 28

meiosis

Question 29

produces four unidentical daughter cells

Answer 29

meiosis

Question 30

condensation of chromosomes and formation of spindle fibers
nuclear membrane disappears
homologous chromosomes pair with each other
crossing over of homologous chromosomes
spindle fibers attach to the homologous chromosomes

Answer 30

prophase 1

Question 31

the paired homologous chromosomes align to the metaphase plate

Answer 31

metaphase 1

Question 32

homologous chromosomes separate and move toward the opposite poles

Answer 32

anaphase 1

Question 33

chromosomes reach the opposite poles and followed by cytokinesis

Answer 33

telophase 1

Question 34

the period between 2 sets of meiotic division

Answer 34

interkinesis

Question 35

chromosomes condense
nuclear envelope disappears (if needed)
spindle fiber forms and attaches to chromosomes

Answer 35

prophase 2

Question 36

chromosomes/sister chromatids align in metaphase plate

Answer 36

metaphase 2

Question 37

sister chromatids separate and are pulled toward the opposite poles

Answer 37

anaphase 2

Question 38

chromosomes uncoil
nuclear envelope forms
cytokinesis will follow

Answer 38

telophase 2
