1. Bellwork T/F Reproduction requires 2 parents
Some organisms reproduce by cell division
New plants can grow from parts of a parent plant such as roots and stems
Offspring of 2 parents always look like one of their parents

2. Sexual and asexual reproduction
SC.7.L.16.3 Compare and contrast the general processes of sexual reproduction requiring meiosis and asexual reproduction requiring mitosis.

3. Reproduction Involves various kinds of cell division
Lets genetic information be passed on to new organisms

4. Uses mitosis – cells divide and form identical cells
What is asexual reproduction?
In asexual reproduction, one organism produces one or more new organisms that are identical to itself.
Most single-celled organisms and some multicellular organisms reproduce asexually.
Uses mitosis – cells divide and form identical cells

5. The organism that produces the new organism is called a parent.
Each new organism is called an offspring.
The offspring produced by asexual reproduction are genetically identical to their parents.

6. How do organisms reproduce asexually?
Organisms reproduce asexually in many ways:
1. Binary Fission: Prokaryotes, including bacteria, reproduce asexually by cell division.
Every organelle is copied and the cell divides in 2

7. Budding :
occurs when a new organism grows on a parent organism and splits off.
Happens through mitosis in multicellular organisms such as yeasts and hydra

8. 3. Spores
is a specialized cell that can survive harsh conditions.
Spores are light and can be carried by the wind.
Both prokaryotes and eukaryotes can form spores

9. 4. vegetative reproduction:
New plants grow from roots, stems or leaves.
Runners = above ground stems
Tubers = underground stems
Vegetative reproduction happens through mitosis.

10. favorable traits are passed on Doesn’t need a partner
What are some advantages of Asexual reproduction?
Quick
favorable traits are passed on
Doesn’t need a partner

11. Name the kind of asexual reproduction

12. Other forms of Reproduction
Multicellular organisms can reproduce asexually.
Some do this by parthenogenesis, in which the female produces young without fertilization.
Other organisms reproduce asexually by regeneration.
Other organisms reproduce asexually by fragmentation, in which segments fall off and become new organisms.

13. What is sexual reproduction?
Most multicellular organisms can reproduce sexually.
In sexual reproduction, two parents each contribute a sex cell to the new organism.
Half the genes in the offspring come from each parent.

14. Males produce sex cells called sperm cells.
What is sexual reproduction?
Males produce sex cells called sperm cells.
Females produce sex cells called eggs.
Sex cells are produced by meiosis.

15. A sperm and an egg join together in a process called fertilization.
Sex cells have half of the set of genetic material found in body cells.
A sperm and an egg join together in a process called fertilization.
When an egg is fertilized by a sperm cell, a new cell, called a zygote, is formed. It has a full set of genetic material.
The zygote develops into a new organism. It grows through mitosis. 15

16. What are the advantages of each type of reproduction?
Asexual reproduction
Quick
favorable traits are passed on
Doesn’t need a partner
Sexual reproduction
It increases genetic variation. Offspring have different traits,
improves the chance of survival in changing environment
Some organisms can use both types of reproduction. This allows them to spread quickly, and adapt to changes in the environment as well.

17. Bellwork: How many parents are involved in sexual reproduction
How many parents are involved in asexual reproduction
Name the process (mitosis or meiosis) that is used in each type of reproduction
identify the type of asexual reproduction taking place in the pictures below

18. Investigating reproductive strategies lab
Read about your assigned organism and describe its characteristics in the data table
Rows 1 and 2 switch organisms and rows 3 and 4 switch organisms and complete the table for your second organism
When you are finished, answer the analysis and conclusion questions on the back
Write both names on the top of the paper and turn in.

19. Bellwork:
Create a Venn Diagram comparing sexual and asexual reproduction. Use the following words:
Identical offspring
Produces offspring
2 parents
1 parent
Genetic variation
Quick
Binary fission
Meiosis
Transmits genetic information from parent to offspring

20. Cell cycle stations: 1 – RTI
2 – microscopes – identify and draw the type of asexual reproduction
3 – Complete mitosis/meiosis review ws and computer review game/quizlet links
