2. Asexual Reproduction
Asexual reproduction is the formation of new individuals from the cell(s) of a single parent.
It is common in plants, less so in animals.

3. Plant Asexual Reproduction
Above ground Stems arch over and take root at the tips, forming new plants (Forsythia, Raspberry and Strawberry)
Horizontal above ground stems are called stolons
Pearson College

4. Plant Asexual Reproduction
Underground stems that serve for food storage and reproduction. Rhizomes, bulbs, corms and tubers
Jeruasalem Artichoke, potato (tuber)
Quackgrass Rhizomes
Irises and day lilies
Pearson College

5. Plant Asexual Reproduction
Amaryllis Bulb
Gladiolus Corm
Pearson College

6. Plant Asexual Reproduction
Leaves—Mitosis along the meristems at the leaf margins produce tiny plantlets that fall off and can take up an independent existence.
Pearson College

7. Plant Asexual Reproduction
Roots—Plants can send up stems from their roots to reproduce. Dandelion, Poplar, Aspen
California Pictures

8. Plant Asexual Reproduction
Plant Propagation—Deliberate propagation by asexual means to keep particularly desirable traits. Grafting removal of a twig (scion) from a desired plant and inserting it into a notch of a cut stump (stock plant).
University of Arizona

9. Plant Asexual Reproduction
Cuttings—Using stems, leaves or roots of plants for asexual reproduction.
Pearson College

10. Plant Sexual Reproduction
Sexual Reproduction—Sperm carried in the pollen from the male part of a flower fuses with the egg in the female part of the flower.

11. Plant Sexual Reproduction
Pollination—Transfer of pollen from the male to the female part of the plant.
Self-Pollination—Pollen of a plant pollinates a flower of the same plant (only some plants can do this, apple trees for example cannot)
University of the Western Cape

12. University of Illinois Urbana Champaign

13. Plant Sexual Reproduction
Cross Pollination—Pollen of a plant pollinates another plant.
Hybrid—The offspring of genetically different plants.
University of the Western Cape

14. Pollination Vectors Wind (grasses) Water (aquatic plants)
Insects (bees, beetles, butterflies and wasps)
Mammals (bats/rodents)
Birds

15. Plant Sexual Reproduction
Complete Flower—A flower having all floral structures, including the calyx (sepals, corolla (petals), stamen (anthers and filaments) and pistil (stigma, style and ovary). (Rose)
Texas Technological University

16. Plant Sexual Reproduction
Incomplete Flower—A flower which lacks one or more floral structures
Perfect Flower—A flower which has male and female floral structures in the same flower. (Rose, Apple, Tomato and Wheat)
Texas Technological University

17. Plant Sexual Reproduction
Imperfect Flower—A flower which has male and female floral structures in separate flowers. (Spruce, Ash and Maples
Monoecious Plant—A plant species having separate male and female flowers on the same plant.(example corn, cucumber, Birch)
Dioecious Plant—A plant species having male and female flowers that are on separate plants. (example buffalograss, Hollies, Yews, Ash, Asparagus and Maple.)
