Competition for light, water, and nutrients is intense among the land plants. How do plants reduce self-shading? What triggers self-pruning? There are different leaf orientations, and each orientation affects light capture. Compare thefollowing as to the type of plant that has each orientation, and describe the advantage. Orientation Type of Plant Advantagevertical leaf orientationhorizontal leaf orientation4. What are mycorrhizae, and what is their role in resource acquisition? Concept Theinformation in the next group of questions should be familiar to you. It covers the concept of water potential, sonow might be a good time to review that lab activity. What is passive transport? What is active transport? What is the role of transport proteins? What are the most important plant cell transport proteins? How do they work? What is membrane potential?
Chapter 36: Resource Acquisition and Transport in Vascular Plants
How can it be established? Explain cotransport. What is osmosis? Plant cells have a rigid cell wall, which adds another factor that affects osmosis: pressure. Define water potential. The understanding of this formula is an objective from Laboratory 1 in theAP Laboratory book. By definition, what is the s of pure water? How does adding solutes to pure water affect water potential? What is pressure potential?

Under what conditions will it decrease? What is the water potential on the left side of tube A? Is the water potential on the right side of tube A positive or negative? Explain, in terms of water potential, why the level of the liquid is higher on the right side oftube A. In tube B, pressure is being applied on the right side. This is much like the pressure exerted bythe cell wall when a plant cell takes up water. Explain, in terms of water potential, why thelevel of liquid is the same on both sides even though the two solutions are not isotonic to eachother. Define these terms:flaccidturgidplasmolysis In the figure below, a plant cell that has an initial water potential of —0. Explain, in terms of water potential, what is happening in each case.

Campbell Biology Chapter 36 Outline
There are two mechanisms that pull water up through the plant, from roots to leaves. Explainroot pressure. The second mechanism that pulls water up through the plant is transpiration-cohesion-tension. Refer to this sketch in your text. Note that water is moving from a region of high waterpotential to a region of lower water potential. The arrow on the left side of the figure shows thisgradient. Beginning from where you stopped in question 29, write an essay to explain themovement of water from the roots to the leaves.
Transport in vascular plants
Include each of these terms in your essay, andlabel them on the figure: lower water potential, higher water potential, hydrogen bonding,adhesion, cohesion, xylem tubes, and stomata. Leaves generally have large surface areas and high surface-to-volume ratios. Give an advantageand disadvantage of these traits. What controls the amount of water loss? Three types of stimuli can cause guard cells to open. Name and explain how each one works. What plant hormone is produced in response to water deficiency? List four different physiological or morphological adaptations of xerophytes, and explain howeach of them reduces water loss. What is translocation? What is a sugar source, and what is a sugar sink? Give an example of each. What cell types transport the sugars? Explain the process of pressure flow by annotating the figure below. Refer to your text, anddivide this process into four steps.

Problem 13 Video Transcript Okay, so this, um this chapter is all about plants, form and function and structure, and then this This question is about what's happening when leaves wilt. So we were to think about a healthy leaf. It's, uh, most notably, it's treated or it has a lot of structure, right? And so what I mean by that is it stands on its own, um, you know, kind of smooth, a little bit stiff and hard, whereas, ah, wilted leaf is very soft. And it has, you know, lacks that structure.
Plant Life Cycle Pdf
So, um, when this structure of the leaf changes, that means the structures of the components on the surface of the leaf are also changing. So if we were to zoom in here on our healthy leaf, what we would find is spin mata. That's there's these little holes for gas exchange, and those holes can exist because of theater tension and structure of the leaf that surrounds the whole. Now, if we zoom in on the east, Amada uh, a wilted leaf, we'll see, is that it's kind of close, right? This whole thing is really kind of closing in on itself. Is pushing it down on dso that stops gas exchange. So on a wilted leaf we don't get photosynthesis. And the reason for that is that these Tamada are closed and that presented prevents, um carbon dioxide from injuring.
