Essential Question: How can I identify and analyze phases of the cell cycle?

STANDARD: 5A THE STUDENT WILL BE ABLE TO DESCRIBE THE STAGES OF THE CELL CYCLE, INCLUDING DEOXYRIBONUCLEIC ACID (DNA) REPLICATION AND MITOSIS, AND THE IMPORTANCE OF THE CELL CYCLE TO THE GROWTH OF ORGANISMS

Onion Root Tip

Interphase: Nucleus is still visibleMost cells are in this phase (G1, S, G2)

Interphase: Nucleus is still visibleMost cells are in this phase (G1, S, G2)

Prophase: Nucleus disappears, Individual chromosomes condense and are visible.

Interphase: Nucleus is still visibleMost cells are in this phase (G1, S, G2)

Prophase: Nucleus disappears, Individual chromosomes condense and are visible.

Metaphase: Chromosomes move to center of the cell and line up.

Prophase: Nucleus disappears, Individual chromosomes condense and are visible.

Metaphase: Chromosomes move to center of the cell and line up.

Anaphase: Chromosomes move apart to opposite sides of the cell.

Prophase: Nucleus disappears, Individual chromosomes condense and are visible.

Metaphase: Chromosomes move to center of the cell and line up.

Anaphase: Chromosomes move apart to opposite sides of the cell.

Telophase: Chromosomes regroup and begin to form two NEW nuclei.

The cell cycle is an on-going process.

The pictures below are “snapshots” of cells at various stages of mitosis.

The cells will continue through the process and repeat until they die.

Cell Cycle Comic

Create a 6-strip comic page describing the process of Mitosis. – Be creative in the representation of your setting and characters– Include thought bubbles and character names (Chromosome, Nucleus,

Cell, DNA, etc…)– Must include the following words (underline/highlight/use different color)

Replication Chromosome Prophase MetaphaseAnaphase Telophase Cytokinesis Interphase
