Cell Reproduction

Biology

What happens to a cell's volume/surface area as the cell becomes larger?

Volume increases faster than the surface area

Define Cell division

A cell divides into 2 daughter cells

Define Mitosis

Division of the nucleus

Define Meiosis

Process of making sex cells

Define cytokinesis

Division of the cytoplasm

What do A+B+C equal?

Interphase

List the correct order of the sequence of the cell cycle (Miosis, cytokinesis, G1, G2, and S)

G1, S, G2, mitosis, cytokinesis

What happens at A(G1)?

Cell is growing

What happens at B (S)?

DNA replicates

what happens at C (G2)?

Cell prepares for mitosis

What happens at D (mitosis)?

Cell divides into 2 daughter cells

In what phase of the cell cycle does an average cell occupy most of its life?

G1 -cell is growing -interphase

What is the structure labeled A called?

Centromere

What is the structure labeled B called?

Sister chromatids

List the phases in the correct order

(Interphase) Prophase, Metaphase, Anaphase, and Telophase

During mitosis, if a parent cell has four chromosomes, how many chromosomes will each of the two daughter cells have?

4

How are cancer cells different from normal cells?

Can't control their growth of rate
