- Figure 30.34 Which of the following statements is false? Negative water potential draws water into the root hairs. Cohesion and adhesion draw water up the xylem. Transpiration draws water from the leaf. Negative water potential draws water into the root hairs. Cohesion and adhesion draw water up the phloem. Transpiration draws water from the leaf. Water potential decreases from the roots to the top of the plant. Water enters the plants through root hairs and exits through stoma.Modified leaves that enable a stem to climb are called __________, whereas modified leaves that cover the winter buds of a dormant woody plant are called __________.

- Examine the winter twig in the picture below of a Horse Chestnut tree, Aesculus hippocastanum. w.m. Draw a sketch of this twig and label all the following structures: terminal bud, lateral bud, terminal bud scale scars (show several sets of terminal bud scars that are visible on the main stem), leaf scars, vascular bundle scars AMooReok DroWhat are the flaws ? Meristematic tissue is the site of mitosis and therefore growth for a plant. Apical meristem is found at the tips of roots and shoots and allows them to produce flowers. Lateral meristem is found along the length of the plant and allows it to increase in width. Intercalary meristem is found in nodes along grasses and allows them to grow from the “base”, which is why grass continues to grow after it is cut. Plants have three organs: leaves, stems, and roots. While the functions of the organs are the same between plants, the structure is different between two large groups of plants: monocots and dicots. Leaves are the site of photosynthesis. In monocots, the vascular tissue is in parallel veins like in grass. In dicots, the veins form a web or net pattern like in a maple leaf. A bulb is a modified leaf that allows the plant to store food. Stems make up the “body” of the plant and support the leaves. In monocots, vascular bundles are found randomly throughout the…Plant Physiology Define or describe and give 2 functions of the plant tissue: Meristem
