1. If a girl carved her initials in the trunk of a maple tree at a point five feet above the ground twenty years ago, and the tree grew at a rate of one foot per year, where can she expect to find her initials today?
2. Describe two mechanisms that move water from the roots to the upper portions of a plant. Indicate the restrictions of each. Which method is more effective in larger, taller plants?
3. Name six species of plants that have leaves. For each plant state whether they are a monocot or dicot. Then for each species state whether their leaves are simple or compound. Then state if their venation is parallel, netted palmate, or netted pinnate. Lastly, state if their leaf arrangement is alternate, opposite, or whorled. (Can you please set this up in a chart with five columns and six rows so I can compare the different plants)© BrainMass Inc. brainmass.com July 17, 2018, 5:38 pm ad1c9bdddf
1. Since the shoot of a plant (including the trunk of a tree) grows vertically from apical meristems (primary meristems), the initials will remain in the same place where she originally carved them. The shoot grows from its extending its top, not by pushing up from the bottom.
2. Transpiration is the evaporation of water from a plant (mostly from the leaves). This evaporation removes water from the air spaces in the leaves, which causes a water deficit in the air spaces. This water deficit is made up by water moving from the cells into the air spaces. But this then caused a water deficit in the cells. As a result, water from the adjacent ...
Transpiration and pressure-flow are discussed in this post.
