Science Vocabulary

3. A plant that completes its life cycle in one growing season.
5. The physiological response of plants to changes in the length of day and night.
7. A waxy, water-repellent layer on the surface of leaves and other plant organs, which helps to reduce water loss.
11. tissue The specialized tissue in plants that transports water, minerals, and nutrients throughout the plant.
14. A type of plant that produces naked seeds, such as conifers and cycads.
15. The growth or movement of a plant in response to a stimulus, such as light, gravity, or touch.
17. The diploid generation in the life cycle of a plant, which produces spores that give rise to the haploid gametophyte generation.
19. A type of angiosperm that has one cotyledon, parallel veins in the leaves, and floral parts in multiples of three.
20. plant A plant that has true vascular tissue, including ferns, gymnosperms, and angiosperms.
22. A structure in the seed of a flowering plant that provides nutrients to the developing embryo.
23. A plant that takes two years to complete its life cycle, often flowering and producing seeds in the second year.
24. A period of reduced metabolic activity in a plant, often associated with unfavorable environmental conditions.

1. A type of plant that produces seeds enclosed in a fruit, including flowering plants.
2. The initial cell formed by the fusion of two gametes, which develops into a new individual.
4. A type of plant hormone that promotes cell elongation and controls the direction of growth.
6. The process by which a seed begins to grow into a new plant.
8. The loss of water vapor from the leaves and stems of plants.
9. plant A plant that lacks true vascular tissue, such as mosses and liverworts.
10. The haploid generation in the life cycle of a plant, which produces gametes that fuse to form a zygote and give rise to the sporophyte generation.
12. A plant that lives for multiple years, often producing new growth each year from the same roots.
13. A type of angiosperm that has two cotyledons, branched veins in the leaves, and floral parts in multiples of four or five.
16. A hair-like structure in nonvascular plants that anchors the plant and absorbs water and nutrients from the soil.
18. A large, divided leaf of a fern or palm.
21. A chemical substance produced by a plant that regulates growth, development, and other physiological processes.
