4. Differences in Reproduction
Asexual
Only one “parent” involved
Offspring is genetically identical to “parent”
No variation = less adaptation and evolution
Examples:
Plantlets
Rhizomes
Tubers
Cuttings
Sexual
Two “parents” involved
Pollination forms a seed
Offspring is NOT genetically identical to parents
Offspring is a combination of genetic information from both parents
Allows for variation and adaptation

5. Asexual Reproduction Also known as vegetative propagation
Many plants produce new plants without seeds; without the mixing of two parents’ genetic material
The offspring are genetically identical to the parent; they are clones!

6. Asexual Reproduction Plantlets

7. Asexual Reproduction Cuttings

8. Asexual Reproduction Tubers and Rhizomes

9. Asexual Reproduction Runners

10. Asexual Reproduction
See our examples on the window sill.

11. Sexual Reproduction
In sexual reproduction a new individual is created from a fusion of gametes (egg cell and sperm cell) from two parents.
Genetic material is combined and offspring may vary from parents.
Genetic variation allows for adaptation and evolution of the species over time

12. Sexual Reproduction
Flowers are the main portion of a plant involved in reproduction.
Let’s build some flowers!
Work w/lab partner but create a flower for each student
Use template provided; materials are on back table
Glue into lab book when complete

13. Sexual Reproduction

14. Sexual Reproduction
For sexual reproduction to take place two steps must occur:
Pollination
Fertilization

15. Sexual Reproduction
Pollination is the transfer of pollen from the male part of a flower to the female part
Depending on species of plant, can be: on the same flower, a different flower on the same plant, or a flower on a different plant of same species
Which of these three types of pollination would allow for genetic variation?

16. Sexual Reproduction
Wind or larger animals often help pollinate flowers by moving pollen around from one place to another, but the major pollinators are insects- bees, flies, wasps, butterflies, etc.

17. Sexual Reproduction

18. Sexual Reproduction
Fertilization is the fusion of the male and female gametes
The pollen transfers down the pistil and into the ovary where it combines with the ovule
The ovule becomes the seed
The ovary becomes the fruit

23. Today’s Assignment
We’re going to use a graphic organizer (T-Chart) to explain, compare and contrast, and illustrate the two types of plant reproduction.
When complete use the attached rubric to grade yourself and then turn in to bin.
