Topic 3.1

Asexual Reproduction

Today’s Plan: 1. Warm Up (3 min)

2. Cell Cycle Review

3. Note Taking

4. Asexual Reproduction JIGSAW

5. Exit Slip (5 min)

Today’s Objective:

Understand how some organisms

use the cell cycle to reproduce,

and investigate some types of

asexual reproduction.

FOCUS QUESTION: How and why do

organisms reproduce asexually?

Cell Cycle Review • Directions: With your group, review the Cell Cycle

image below and then answer the questions that follows.

Cell Cycle Review

1. In your own words, what is the goal of the cell cycle?

2. Why do you think it would be important for cells to go through the cell cycle?

1. Each species on Earth must reproduce in order to maintain its existence. If they did not reproduce, the species would go extinct.

Note Taking

2. Multicellular Organisms

Cell division is used for:

• Growth

• Maintaining the body

3. Unicellular Organisms

Cell division is used for

• reproduction

4. Asexual Reproduction

ONE parent gives rise to a single, genetically identical offspring (daughter cell)

Asexual Reproduction JIGSAW • INTRODUCTION

Asexual Reproduction JIGSAW • Directions: Each member of your group will be

assigned a reading: A, B, C, or D. The person assigned to each reading will read about a particular TYPE OF asexual reproduction and become an expert on that subject. Then, that person will present what they have learned to their group members.

JIGSAW SHARE OUT:

• Each member will read their notes about the types of asexual reproduction to their group.

• The group will take notes from what each person presents. NO COPYING NOTES FROM PAPERS!!

CLASS DISCUSSION Analysis Questions:

1. Why would an organism reproduce asexually? What are the advantages?

2. Do most animals reproduce sexually or asexually? How do you know?

This stopwatch is timing how long it takes you to get ready. It will stop after everyone

- has completed a warm up - has their binder in front of them - has today’s work - is sitting in their assigned seat - has given 3 seconds of silence.

Your class will gain points based on how quickly this happens.

Exit Slip (5 min) 1. Return to your assigned seat

2. Complete the exit slip

3. Clean up your workstation

4. Secure all handouts in your binder

5. Put your binder away.

1. How many parents are needed to perform asexual reproduction?

2. What is one advantage of asexual reproduction?
