Across
- 4. a plant that has seeds unprotected by an ovary or fruit. Include the conifers, cycads, and ginkgo.
- 5. the development of a plant from a seed or spore after a period of dormancy
- 7. the embryonic leaf in seed-bearing plants, one or more of which are the first leaves to appear from a germinating seed
- 10. plants that can live for two or more growing seasons
- 12. a plant that has flowers and produces seeds enclosed within a carpel. Includes herbaceous plants, shrubs, grasses, and most trees.
- 13. a group of flowering plants belonging to the angiosperms family, characterized by having two photosynthetic cotyledons in the seed that may emerge from the ground when the seed germinate
- 14. the vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem
- 15. flattened structure of a higher plant, typically green and blade-like, that is attached to a stem directly or via a stalk. Are the main organs of photosynthesis and transpiration.
- 17. plants that grow for one long season, often into the fall, then die with the onset of freezing weather
- 18. the sweet and fleshy product of a tree or other plant that contains seed and can be eaten as food
- 20. the part of a plant which attaches it to the ground or to a support, typically underground, conveying water and nourishment to the rest of the plant via numerous branches and fibers
Down
- 1. the seed-bearing part of a plant, consisting of reproductive organs (stamens and carpels) that are typically surrounded by a brightly colored corolla (petals) and a green calyx (sepals)
- 2. the exhalation of water vapor through the stomata
- 3. An herbaceous plant having an embryo with a single cotyledon, usually parallel-veined leaves, and floral organs arranged in multiples of three
- 6. when plants prepare their soft tissues for freezing temperatures, dry weather, or water and nutrient shortage.
- 8. the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.
- 9. any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width which allows movement of gases in and out of the intercellular spaces.
- 11. a process of sexual reproduction, which occurs after pollination and germination
- 16. the transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization
- 19. the main body or stalk of a plant or shrub, typically rising above ground but occasionally subterranean.
