Across
- 1. A kind of carbohydrate manufactured by plants and stored in the seeds, roots, and fruit as a reserve energy supply.
- 4. Any organism in its earliest stages of development.
- 6. coat The hard outer layer of a seed; the protective covering, or integument, also called testa. Seedling – The early growth stage of a plant grown from seed as it emerges above the ground surface.
- 7. The primary descending root, usually conical, of a plant from which lateral branching roots may develop; e.g., as in carrots and alfalfa.
- 11. The first leaf of a germinating monocot which sheaths the succeeding leaves. Cotyledon – The first leaf to be developed by the embryo in plant seeds, also called the seed leaf.
- 12. root The main descending axis of a plant; the pole of the embryo opposite the shoot.
- 14. A flattened outgrowth from a plant stem, varying in size and shape, usually green, which is concerned primarily with the manufacture of carbohydrates by photosynthesis.
- 16. The body that, after fertilization, becomes the seed; the egg-containing unit of the ovary.
- 17. A common sugar that serves as the building block for many complex carbohydrates.
- 20. Plant whose seeds have two cotyledons or seed leaves, such as beans.
- 23. A physiologic state where the seed embryo is incapable of growth; a state when the metabolic processes are slowed. Especially applies to respiration.
- 24. The lower portion of a plant bearing neither leaves nor reproductive organs which mostly develops underground and anchors the plant in the soil. It bears the root hairs, which absorb water and mineral nutrients.
- 25. – Plant having a single cotyledon or seed leaf such as corn.
- 27. The appearance of the first leaves of the crop plant above the ground.
Down
- 2. The short stem of an embryo seed plant, the portion of the axis of the embryo seedling between the attachment of the cotyledons and the radicle.
- 3. The outer coat of a seed, also called seed coat.
- 5. The embryonic roots of seed plants.
- 8. In a germinating seed plant, the primary bud that develops into the primary stem. In a dicotyledon, such as beans, it is located between the cotyledons.
- 9. The capacity of seeds to germinate.
- 10. The part of the axis of an embryo above the region of attachment of the cotyledons.
- 13. root Branches of the primary root are often fibrous and referred to as secondary roots; become the permanent roots of many monocotyledons.
- 15. A large complex protein molecule produced by the body that stimulates or speeds up various chemical reactions without being used up itself; an organic catalyst.
- 18. The embryo of a plant; also kernel of corn, wheat, etc., which botanically are seed like fruits as they include the ovary wall.
- 19. The nutritive portion in some seeds that originates in the embryo sac, but that is outside the embryo.
- 21. hair A hairlike growth on an epidermal cell of the root. It absorbs water and mineral nutrients for the plant.
- 22. The portion of a seed contained within the seed coat.
- 26. An enzyme that converts starch to maltose.
- 28. Sprouting of a seed, and beginning of plant growth.
