Telophase - Definition, Examples, Quiz, FAQ, Trivia
Discover how cells complete the amazing process of division
What is Telophase?
Telophase is the final stage of cell division where the cell prepares to become two separate cells. It's like the grand finale of a fireworks show where everything comes together to create something new!
During telophase, the chromosomes (which contain our genetic information) have finished moving to opposite ends of the cell. The cell then starts to form two new nuclear membranes around each set of chromosomes. Think of it like building two new control centers for what will become two new cells.
Science Fact!
Telophase comes from the Greek words "telo" meaning "end" and "phase" meaning "stage" - so it literally means "the ending stage"!
Telophase in Mitosis and Meiosis
Telophase happens in both types of cell division: mitosis and meiosis, but there are some important differences:
Telophase in Mitosis
Creates two identical daughter cells with the same number of chromosomes as the parent cell
Telophase I in Meiosis
First division - creates two cells with half the chromosomes of the parent cell
Telophase II in Meiosis
Second division - creates four unique sex cells (gametes) with half the chromosomes
The main difference between telophase in mitosis and meiosis is that in meiosis, the cell divides twice, resulting in four cells instead of two, and each cell has only half the number of chromosomes of the original cell.
Did You Know?
Meiosis only happens in reproductive cells (sperm and egg cells), while mitosis happens in all other cells of your body!
Telophase and Cytokinesis
Cytokinesis is the process that actually divides the cell into two separate cells. It usually begins during telophase and completes after telophase ends. Think of telophase as preparing everything for the split, and cytokinesis as actually doing the splitting!
Cleavage Furrow
In animal cells, a ring contracts to pinch the cell into two
Cell Plate
In plant cells, a new cell wall forms between the two cells
Completion
Two separate, identical daughter cells are formed
While telophase and cytokinesis are separate processes, they work together so closely that they often appear to happen at the same time. Telophase prepares the genetic material, and cytokinesis divides the rest of the cell contents.
Cell Division Stages
Telophase is part of a larger process called the cell cycle. Understanding where telophase fits in helps us see the bigger picture of how cells divide:
Interphase
The cell grows and copies its DNA
Prophase
Chromosomes condense and become visible
Metaphase
Chromosomes line up in the middle of the cell
Anaphase
Chromosomes separate and move to opposite poles
Telophase
Nuclear membranes reform around chromosomes
Cytokinesis
Cell divides into two separate daughter cells
Telophase is the final stage of nuclear division, coming right after anaphase and before cytokinesis. It's like the calm after the storm when the chromosomes have finished moving and the cell prepares to become two.
Telophase vs Anaphase
Anaphase is when chromosomes move apart, while telophase is when they arrive at the poles and new nuclei form. Anaphase is the movement, telophase is the destination!

Interesting Telophase Facts
Discover some amazing facts about telophase and cell division!
Speedy Division
Some cells in your body divide incredibly fast! For example, cells in your bone marrow can complete the entire cell cycle (including telophase) in just 24 hours to create new blood cells.
Historical Discovery
Scientists first observed and named the phases of cell division in the late 1800s. The term "telophase" was coined by German scientist Walther Flemming, who is considered the father of cytogenetics.
Microscopic Wonder
Telophase is best observed under a microscope with at least 400x magnification. Scientists often use special dyes to make the chromosomes more visible during this phase.
Growth Through Division
Your body performs cellular division trillions of times throughout your life! When you were just a tiny embryo, telophase helped you grow from one cell to trillions of cells.
