It is a means of reproduction for single-cell organisms.
Much of science deals with constructing explanations of how things change and how they remain stable. Notes for the Teacher Cell division and the cell cycle are standard pieces of a biology curriculum.
What makes this lesson stand out is the use of hand gestures to cue vocabulary and sequence. The kids love doing it together with me, especially after I make a ridiculous display of getting into it!
I giggle a bit thinking of the number of students who flash me one of our mitosis dance hand gestures as I walk down the hall.
I make a point to keep colored pencils out on desks or in open drawers labeled and available to students anytime they wish to get up and retrieve them, along with highlighters, rulers, and drawing paper.
The more colorful their drawings, the morel likely I am to see them refer back to them again later on in our unit and throughout our exam review sessions.
I am also less likely to find them on the floor or in the recycle bin! More and more, I am finding that these tiny, foundational shifts have a larger impact on the learning culture and engagement in our classroom and I am excited for the students to experience what it is like to be driving their own education!
Introducing Cell Division 10 minutes 1. Ask students to take out materials to take notes today use whatever method you typically use.
Provide colored pencils or markers for greater student engagement and more precise note taking and sketching. Announce that today you will be going deeper into the concept of cell division.
This brief flow chart ties together terms like mitosis, meiosis, body cells, sex cells into the idea of asexual vs. Leave this up on display for the rest of the unit. You will find students referring back to it each time they acquire new vocabulary or add to their understanding about each specific cell division process.
Focusing on the Cell Cycle and Mitosis 20 minutes 1. Remind students of the conversation you have already had and the summary of steps you created together on the board about the cell cycle. Tell students that today you will be working to understand the process cell division by using diagrams and gestures.
As you draw each phase, talk students through each one and write down the most important points for each. Follow this format to give students time to draw, read, listen, and understand: Write down the name of the phase. Draw the phase using colored pens. Give students time to draw in their notes before moving to the next step.
Write in bullet points the main events that happen in that phase. Read each bullet point slowly as students write it in their own notes. Use the diagram to point out the events in action in your drawing.
Take clarifying questions as they come up. Typically, students will be focused on writing and drawing and more specific questions come up later in the lesson series.
I typically take up the entire board and save the drawings of each for the rest of the unit. Students come up to the board throughout our time studying this topic to discuss, compare, and ask questions.
They often like to take photos of it as well to compare to their own notes. The use of color, the bullet points, vocabulary list, and size of the drawings helps students use them effectively each day of the unit as they add in additional knowledge about the phases and discuss them with their peers.
Write out the essential vocabulary for this topic as a list on the side of the board phase drawings: Underline them in your drawings with bullet points each time they appear. Ask students to help you find them.
Remind students that these sketches and explanations will be posted in the room for the rest of the unit and that we will be referring to them each day as we learn more about cell division and connect what we learn into a broader sense of the different types of reproduction, their outcomes, and their purposes.For an overview of the SF State General Education program, visit our Introduction to General Education..

CHAPTER 3: Cell division. Subsections"A" Introduction.
Growth in shape (width), size (height), and number (population), is characteristics of all living being including plants all are due to cell division.
Not all cells can “hear” a particular chemical message. In order to detect a signal (that is, to be a target cell), a neighbor cell must have the right receptor for that signal.
When a signaling molecule binds to its receptor, it alters the shape or activity of the receptor, triggering a change inside of the cell.

Introduction to Cell Division This follows the page about the structure of an animal cell. Living cells divide to form new cells in order to repair worn-out or damaged tissues throughout an organism, and (in the gametes only) to enable the exchange of genetic material .
