Plant Structure

3. A type of root system common in dicots, with one main root.
5. A plant tissue that provides flexible support with thickened cell walls.
7. The central part of the root or stem, often used for storage.
9. A tissue found in the bark of trees, part of the periderm.
10. A plant organ that is typically above ground and supports leaves.
11. A type of root system common in monocots, consisting of many thin roots.
13. The innermost layer of the root cortex, regulates water passage.
16. The thickened secondary tissue that supports the plant.
19. The middle layer of a leaf containing photosynthetic cells.
22. A plant tissue that provides support and has thickened cell walls.
23. The area at the tip of the root that protects the growing root.
24. Plants adapted to arid environments with special features to reduce water loss.

1. A type of xylem cell that helps transport water and provide structural support.
2. A tissue system involved in the transport of water and nutrients.
4. The outermost layer of cells in a plant.
6. A region in roots and stems where continuous cell division occurs.
8. A layer of actively dividing cells between xylem and phloem tissues.
9. The main type of tissue for photosynthesis found in leaves.
12. The primary meristem that gives rise to the epidermis.
14. The tissue system that covers and protects the plant.
15. The main photosynthetic tissue in leaves.
17. A type of vascular tissue responsible for transporting food.
18. The main type of vascular tissue responsible for transporting water.
20. The part of a leaf that attaches to the stem.
21. A type of meristem that contributes to the secondary growth of plants.
