1. Plant Reproduction

2. Sporophyte Plant structures that produces spores Asexual reproduction

3. Gametophyte Plant structures that produces gametes Sexual Reproduction

4. Gymnosperms -plant that has seeds -gametophyte (located on the flower) -sporophyte (trunks, stems, roots leaves etc.

5. Asexual Reproduction 1. Vegetative Plant reproduction from a piece or specific organ. Stolon, Bulbs, Rhizomes, Stem tubers 2. Spores Specific asexual reproductive structures called spores. The new plant is formed without fertilization

6. Vegetative 1. Stolons -stems parallel to the ground -when they touch the ground, they can form roots and a new plant Ex. Grass, strawberries,

7. 2. Bulbs - Underground short stem covered by leaves that protect them -These stems can be used as reproductive structures and form new plants Ex. Garlic

8. 3. Rhizomes - underground root-like stem -One rhizome can form multiple superficial plants Ex. Ginger, Bamboo

9. 4. Stem Tubers - Special underground stems, enlarged to store substances that can generate new plants Ex. potato

10. Sexual Reproduction Flowers -Sexual reproductive organs in plants -Can be unisexual or hermaphrodite Pollen -where the male gametes can be found Ovules -where the female gametes can be found

11. 1. Vegetative part Calyx -external cover of the flower -group of leaves called sepals Corolla -internal cover of the flower -group of leaves called petals -usually with characteristic colors

12. 2. Reproductive part Stamen -male reproductive part of the flower -fabrication and storage of pollen Pistils -female reproductive part -fabrication and storage of ovules -must have structures that allow pollen make the fertilization with ovules
