- 3. Pathway through cell walls and intercellular spaces for water movement.
- 8. Cells in phloem that assist with the transport of nutrients.
- 9. Waxy/suberin barrier in plant roots that regulates water and mineral uptake.
- 10. This is a layer of cells, one to several cells thick, just inside the endodermis.
- 12. Force that helps pull water upward through the xylem, because of polar and polar interaction.
- 13. Process of moving substances from regions of higher concentration to lower concentration.
- 15. Process by which plants lose water vapor through stomata.
- 16. A basic plant tissue that are thin-walled, closely packed with no or small intercellular space.
- 18. Openings on leaf surfaces that control gas exchange.
- 20. Tissue responsible for transporting water and minerals in plants.
- 21. Movement of substances against a concentration gradient such as movement of H+ from companion cell to source, requiring energy.
- 24. Movement of water through plant tissues driven by evaporation from leaves.
- 26. This properties of xerophyte indicate a thick, fleshy stem To store water.
- 27. Cells that regulate the opening and closing of stomata.
- 28. Tissue responsible for transporting sugars and other organic nutrients.
- 29. This properties of xerophyte reduces the amount of surface area from which water vapour can diffuse.
- 31. Cells in roots that increase surface area for water absorption.
- 32. Force that helps pull water upward through the xylem, because of polar and non-polar interaction.
Down
- 1. This properties of xerophyte reduces the quantity of water that can diffuse through the surface of the leaf into the air.
- 2. A modified form of parenchyma in which the corners of the cells have extracellulose thickening, providing extra support, as in the midrib and the corners or square stems.
- 4. This tissue has many large air spaces between the cells for gas diffusion.
- 5. Process involving the loss of water vapor from plant leaves.
- 6. This properties of xerophyte on its surface helps reduce movement of air, helping to trap humid air.
- 7. One-cell thick, continuous layer outside of the plant.
- 11. One-cell thick, surrounding vascular bundle in the stem and roots.
- 14. Phloem contains unique tube-like structures called ...
- 17. Movement of water molecules through a selectively permeable membrane.
- 19. A plant tissue consisting of thick-walled cells with a purely mechanical function (strength and support); the cell walls have usually become impregnated with lignin.
- 22. Column-shaped, located near upper epidermis where they receive many sunlight, therefore contains more chloroplasts.
- 23. Process by which plants transport organic nutrients through the phloem.
- 25. Pathway through the cytoplasm of plant cells connected by plasmodesmata.
- 30. Pressure exerted by the plasma membrane against the cell wall, providing structural support.
