Cell Division

Question 1

Chromatin

Answer 1

Unwound DNA looks like spaghetti

Question 2

Chromatid

Answer 2

Condensed DNA looks like elbow pasta

Question 3

Chromosome

Answer 3

2 identical sister chromatids joined at centromere. Centromere little dot. Looks like an X

Question 4

Why do cells divide

Answer 4

RGR

Reproduction Growth Repair

Question 5

How does the cell know how to divide

Answer 5

DNA has instructions for all the cell’s activity

Question 6

3 parts

Answer 6

IMC

Interphase Mitosis Cytokenisis

Question 7

Interphase what happens

Answer 7

Cell doubles in size, DNA replicates, Organelles double in number

Question 8

Prophase what happens

Answer 8

DNA forms chromosomes, spindle forms, centrioles moved toward opposite poles, Nuclear membrane begins to disappear

Question 9

Metaphase what happens

Answer 9

Nucleus has disappeared completely, chromosomes in the middle of cell spindle fibers attach centromeres

Question 10

Anaphase what happens

Answer 10

Centro-meters divide, chromatins separate and move to opposite poles

Question 11

Telephase what happens

Answer 11

Nuclear membrane forms around each group of chromosomes and they unwind, cleavage furrow forms

Question 12

Cytokinesis what happens

Answer 12

Cytoplasm divides one cell becomes two identical cells

Question 13

Centrioles and Chromatin

Answer 13

Organelles needed for division

Strands of DNA

Question 14

Chromatid and spindle fibers

Answer 14

Condensed DNA

Attach to centromere for division
