Cell Division Notes
Key Concepts: Introduction
(1) How do multicellular objects like humans and trees grow so big?
(2) If all life on earth begins as a single cell, how do some of them become complex
multicellular organisms?
Terminology
CELL CYCLE –
DAUGHTER CELLS –
THREE STAGES OF CELL DIVISON
Stage 1: Interphase (the period before cell division)

Growing –

Copying DNA –

Preparing for Division –
Stage 2: Mitosis (one nucleus divides to create two)

Phase 1: Prophase

Phase 2: Metaphase

Phase 3: Anaphase

Phase 4: Telophase
Stage 3: Cytokinesis (completes the process of cell division)

Animal Cells –

Plant Cells –
Illustrating Cell Division
* Draw what an animal cell would look like in each of the stages of cell division. Be sure to
include key cell parts in your sketches.

Key Concepts: Conclusion
(1) Cell division is also known as the CELL CYCLE. Explain why the word “CYCLE” is
appropriate to use to describe the process of cell division.
(2) During cellular reproduction, a cell must divide in order to multiply. Explain this
statement.
