Part D

2. Opening in the leaf epidermis through which water vapor and oxygen pass out of the leaf and carbon dioxide passes into it
6. Plant known as a naked seed plant because its seeds do not develop within ovaries
7. haploid spore produced within the ascus of ascomycetes
8. Stemlike hypha that grows parallel to a fungus's growth medium
9. Male reproductive structure in some plants, including mosses and liverworts
11. Noncellular protective coating on the exterior surface of an organism, such as the waxy covering on leaves and insect exoskeletons that helps prevent water loss through evaporation
12. Flowering plant whose seeds develop within ovaries
14. Modified underground stem swollen with stored food
15. Protective structure formed from an enlarged, thickened ovary wall that contains angiosperm seeds
16. Modified stem with most of its food stored in layers of short, thick leaves that wrap around the stem
17. Root tissue that transports water and nutrients inward through the root; may store sugar and starches

1. Primary plant root that grows longer and thicker than other roots
2. Structure in ferns, some protists, and some fungi that contains spores
3. Angiosperm whose seeds have one cotyledon
4. Vascular tissue responsible for the transport of nutrients and the products of photosynthesis throughout the plant
5. Thin heart-shaped structure formed from the gametophyte of a fern
7. Female reproductive structure in some plants, including mosses and liverworts
9. Tiny Sac in which fungal spores develop for sexual reproduction in ascomycetes
10. Asexual spore produced in an ascomycete
13. Organism at an early stage of development
