What is the purpose of the G2 phase in the cell cycle?
A) The cell grows and performs normal functions
B) The cell divides its cytoplasm into two daughter cells
C) The cell prepares for mitosis by producing needed organelles like ribosomes and mitochondria
D) The cell’s DNA is copied
The cell prepares for mitosis by producing necessary organelles such as ribosomes and mitochondria

What happens during telophase in mitosis?
A) Chromosomes condense and spindle fibers form
B) Sister chromatids are pulled apart to opposite poles of the cell
C) The nuclear membrane reforms around each set of chromosomes, and the cell begins to split
D) DNA replication occurs
The nuclear membrane reforms around each set of chromosomes, and the cell begins to split

Which phase of mitosis does this illustration represent?
telophase

Name and draw a picture of the first phase of the cell cycle and list the three stages (in order) within this phase.
Interphase
G1, S, G2

Question: How does mitosis ensure that daughter cells are genetically identical to the parent cell?
A) It duplicates and evenly divides chromosomes, ensuring each daughter cell gets an identical set of DNA
B) It randomly distributes chromosomes, leading to genetic diversity
C) It fuses the two daughter cells into one large cell
D) It allows uncontrolled cell growth
Mitosis ensures genetic consistency by precisely aligning and separating duplicated chromosomes so that each daughter cell receives an identical set of DNA.
