Chapter 28, Problem 4CT
Summary Introduction
To determine: The reason for plant death if its stomata is closed or opened all the time.
Concept introduction:
Stomata are the minute pore or small opening that arises from the kidney shaped guard cells of plant leaves. Stomata are present in the upper and lower surfaces of the leaves. They help for exchanging gases in and out of the cell and also help for transpiration (maintaining the water level in cells).

- The stomata are tiny openings in leaves that, when open, allow water to evaporate. In what circumstances do you expect that stomata to be closed?arrow_forwardPlant stomata have guard cells. Guard cells will; Always leave the stomata open Close the stomata when conditions are moist Close the stomata when conditions are dryarrow_forwardThe water which is lost through the stomata is replaced by what?arrow_forward
- Which is true regarding regulation of stomata? Light provides a signal leading to the pumping of K+ and Cl- out of the guard cells Low CO2 concentration in leaves is a signal to close stomata Abscisic Acid is a hormone that signals for stomata to open Stomata remain open under hot, dry conditions If guard cells are turgid (full of water), the stomatal pore is openarrow_forwardTerrestrial plants have stomata on the surface of their leaves. A single stoma is surrounded by two guard cells that change shape in response to environmental factors and open or close the stoma. Which of the following best explains how the structure of the leaf is used in processes that occur in the plant?arrow_forwardWhy are stomata necessary?arrow_forward
- A mutation causes the vascular cambium in a plant to stop working. How does this impact cellular respiration? The stomata would remain open and release water vapor. The guard cells would remain closed and store water vapor. The leaves would not be able to release glucose for energy production. The xylem would not be able to transport water to the rest of the plant.arrow_forwardPaul Klein has a favorite plant which is Duranta repens. He places the plant aloe in a covered airtight container that is exposed to the sunlight. Assume a watering system is provided. What will happen to the plant? Will it live or die? Why?arrow_forwardCan monocot leaves resist drought better than dicot leaves? Why or why not?arrow_forward
- Welwitschia is a genus of plant that lives in the Namib andMossamedes Deserts in Africa. Annual rainfall averages only2.5 cm (1 inch) per year. Welwitschia plants contain a large numberof stomata (22,000 per cm2), which remain closed most of the time.Can you suggest how a large number of stomata would be beneficialto these desert plants?arrow_forwardAbout STOMATA What is the benefit of keeping them open? What it the benefit to keeping them closed? What would you expect the leaves to look like for a tree that lives in very dry conditions? What would you expect the leaves to look like for a tree that lives in very wet / very crowded conditions? Why?arrow_forwardVernalization is a plant response to: Light Gravity Physical contact None of the above Plant epidermis secretes a waterproof substance called: Cuticle Wax Periderm covering Pectin Plant transpiration accounts for what % of atmospheric water vapor? 50% 90% 5% 75%arrow_forward
