| 1159813773 | In angiosperms , xylem consists of tracheids and... | vessel elements | 1 | |
| 1159813774 | Vascular tissue in plants consists of | xylem and phloem | 2 | |
| 1159813775 | To observe mitosis, which part of the plant should a student examine under a compound microscope? | tip of the shoot and tip of the roots | 3 | |
| 1159813776 | The layer of cells that encloses the vascular tissue in the central region of a root is the | endodermis | 4 | |
| 1159813777 | The vascular cylinder of a root consists of | xylem and phloem | 5 | |
| 1159813778 | Root pressure is produced where and by what? | Vascular cylinder by active transport | 6 | |
| 1159813779 | What are the three main functions of stems? | Carries water and nutrients between stems and leaves, produce leaves, branches and flowers, hold leaves up to the sun for photosynthesis to occur, and transport substances throughout the plant. | 7 | |
| 1159813780 | Many cacti, such as saguaros and barrel cacti, have large stems and no leaves. What function of the leaves is taken on by the stems of such cacti? | Photosynthesis | 8 | |
| 1159813781 | During primary growth, a stem... | grows taller and increases in length | 9 | |
| 1159813782 | Oxygen and carbon dioxide move in and out of the leaf through the | stomata (see diagram on worksheet) | 10 | |
| 1159813783 | In Figure 23-1, water pressure in the ........... is high. | guard cells | 11 | |
| 1159813784 | In many plants, stomata are found only on the lower surface of the leaf. The most likely explanation for this fact is that.... | water loss will be less on the lower shaded surface than in the direct sun. | 12 | |
| 1159813785 | The attraction of water molecules to other kinds of molecules (like those in glass and plastic for example) is called... | adhesion | 13 | |
| 1159813786 | What are the parts of the pressure-flow hypothesis? | the movement of water into a nutrient rich region of the phloem decreases the pressure in that region. | 14 | |
| 1159813787 | Ground tissue is found in what parts of a plant? | Stem, root, and leaf | 15 | |
| 1159813788 | In plants, the main organs in which photosynthesis takes place are | leaves | 16 | |
| 1159813789 | Root hairs are made up of ........... tissue. | dermal | 17 | |
| 1159813790 | In plants the opening and closing of stomata balance water loss with the need for | sun and CO2 (carbon dioxide) | 18 | |
| 1159813791 | ............ at the tips of stems and roots produce rapid growth in plants | Meristems | 19 | |
| 1159813792 | In Figure 23-2, structure B is the ............, which includes a waterproof zone called the ................ | endodermis......casparian strip | 20 | |
| 1159813793 | In xylem and phloem, the cells that keep their nuclei and organelles are the.... | companion cells. | 21 | |
| 1159813794 | Contrast the flow of materials in xylem and phloem? | Xylem: water....up Phloem: Nutrients....up and down | 22 | |
| 1159813795 | A scientist discovers a new plant. She notes that the plant forms wood as it becomes taller. Did the scientist discover a monocot or a dicot? Explain. | Dicot because wood is the secondary growth of dicots as monocots only produce primary growth. | 23 | |
| 1159813796 | During a very hot, sunny day, are stomata likely to be open or closed? Explain | Closed so they don't lose water. | 24 |
