Cell Cycle

Question 1

Cell Cycle

Answer 1

The life cycle of a cell. The series of growth and development steps, involving the birth of the mother cell and the division into two daughter cells.

Question 2

Two phases of the cell cycle

Answer 2

Interphase, mitotic phase

Question 3

Interphase

Answer 3

The cell grows and makes a copy of its DNA

Question 4

Mitotic Phase

Answer 4

The cell separates its DNA into two sets and divides its cytoplasm to make two new cells

Question 5

Interphase is split into 3 stages

Answer 5

G1, S, G2

Question 6

G1 Phase

Answer 6

Cell grows physically larger, copies organelles, makes molecular building blocks needed in later steps

Question 7

S Phase

Answer 7

Cell synthesizes complete copy of the DNA in its nucleus. Duplicates centrosome (microtubule-organizing structure). Centrosomes help separate DNA during Mitotic phase

Question 8

G2

Answer 8

Cell grows more, makes proteins and organelles, begins to organize contents in preparation of mitosis

Question 9

Mitotic Phase Involves 2 Stages

Answer 9

Mitosis, Cytokinesis

Question 10

Mitosis

Answer 10

Cell division involving a mother cell splitting into two daughter cell. DNA is replicated, and is pulled apart by mitotic spindle.

Question 11

4 Stages of Mitosis

Answer 11

Prophase, Metaphase, Anaphase, Telophase

Question 12

Cytokinesis

Answer 12

Cytoplasm splits into two cells

Question 13

How do animal and plant cells divide the cytoplasm?

Answer 13

• Animal cells divide by a cleavage furrow: the cell pinches inwards
• Plant cells divides by the formation of a cell plate, which eventually becomes the cell wall of two individual cells
