Across
- 6. root, The first organ/root to appear when a seed germinates.
- 7. root system, A dense network of roots with no main root that grows closer to the soil surface.
- 11. roots, A type of root which secretes phosphatases which allows the plant to extract as much phosphorus from phosphorus-poor soil as possible.
- 12. apical meristem, A small region at the tip of a root in which all cells can repeat division and from which all primary root tissues are derived; Also called the root apex.
- 13. strip, Part of the endodermis, helps to regulate apoplastic movement of nutrients.
- 14. lateral meristem, Cells found at the margins of roots associated with lateral growth.
- 16. roots, Adventitious roots that grow above the ground; typically used for support.
- 18. A short, thin filament found in bryophytes, mosses, hornworts, and liverworts that anchors the growing body of the organism to a substratum and that is capable of absorbing nutrients.
- 19. cap, A thin layer of tissue that protects the apical meristem.
- 21. A sponge-like tissue of specific aerial roots that aids in atmospheric nutrient absorption.
- 22. root, The smaller roots that emerge horizontally from the taproot or the main root.
- 24. The layer of soil bound to the root by mucigel and root hairs.
- 25. roots, A type of modified root that is used for nutrient storage.
- 26. roots, A type of aerial root that traps and transports oxygen to other parts of the plant.
- 27. of elongation, A region of the root containing cells that do not divide but instead elongate rapidly.
- 28. A coordinated process of differential growth by a plant in response to gravity pulling on it.
- 29. plants, Plant which creates basket litter traps with their roots to collect falling leaves to use as nutrients.
- 30. mycorrhizae, When the hyphae of the fungi penetrate the cell walls and form bundles to exchange nutrients; Also known as endomycorrhiza.
Down
- 1. The symbiosis between fungi and plants.
- 2. Roots in the air with no direct connection to support or aeration.
- 3. Part of the ground tissue that creates a boundary around the vascular tissue to control the movement of nutrients into the root.
- 4. tissue system of root, The cortex and pith of the root cell that facilitates the storage of sugars or starches.
- 5. A layer of cells surrounding the xylem and phloem that helps to initiate and regulate the growth of lateral roots.
- 8. cylinder, The bundle of vascular tissue that is inside the exodermis.
- 9. When the hyphae of the fungi do not penetrate the cell walls but rather grow around them to exchange nutrients.
- 10. Part of the ground system that creates a boundary that separates the inner vascular tissue from the outer cortex.
- 12. The descending axis of plant, normally underground, which serves to anchor the plant and absorb and conduct water and nutrients.
- 15. system, The main root that grows down vertically; from which many smaller lateral roots arise
- 17. of maturation, The area where freshly formed root cells mature and strengthen; This is also the zone where root hairs are formed; Also called the root hair zone.
- 20. tissue system of root, The outer protective layer of the primary root body.
- 23. roots, Roots that form from any non-root tissue and are produced both during normal development.
- 31. A pod on the root which houses bacteria used to exchange nutrients with the plant.
