Lesson 4 - Mitosis

Question 1

Cell Cycle

Answer 1

cyclic series of events in the life of a dividing eukaryotic cell

Question 2

involves a single nuclear division in which the two daughter cells formed are genetically identical to each other and to the original cell

Answer 2

Mitosis

Question 3

What are the stages of Cell Cycle?

Answer 3

Interphase, Prophase, Metaphase, Anaphase, Telophase

Question 4

cyclic series of events in the life of a dividing eukaryotic cell

Answer 4

Cell Cycle

Question 5

Interphase

Answer 5

Cell prepares for division, longest part of the cell cycle

Question 6

G1 phase

Answer 6

Cell grows and produces more organelles

Question 7

S Phase (synthesis)

Answer 7

Cell’s DNA is being replicated. Chromosomes duplicates

Question 8

G2 Phase

Answer 8

Cell continues to grow and check if its ready for mitosis/cell division

Question 9

Nuclear membrane breaks down, then chromatin condenses, and forms chromosomes

Answer 9

Prophase

Question 10

Duplicated chromosomes line up across the middle of the cell

Answer 10

Metaphase

Question 11

Sister chromatids pull apart to opposite poles of the cell

Answer 11

Anaphase

Question 12

Nucleolus forms around the chromosome at the opposite ends, it begins to decondense back into chromatin

Answer 12

Telophase

Question 13

Cytokinesis

Answer 13

splits the cytoplasm and completes the division into two daughter cells

Question 14

Prophase

Answer 14

Nuclear membrane breaks down, chromatin condenses and forms chromosomes

Question 15

Metaphase

Answer 15

duplicated chromosomes line up across the middle of the cell

Question 16

Anaphase

Answer 16

sister chromatids pull apart to opposite poles of the cell

Question 17

Telophase

Answer 17

nucleolus forms around the the chromosome at the opposite pole, it begins to decondense back into chromatin

Question 18

What causes the movement of chromosomes towards the opposite poles?

Answer 18

Its spindle apparatus

Question 19

What are spindle fibers and cell plate made of?

Answer 19

Microtubules and vesicles containing cell wall materials like cellulose
