All of the following are the features of guard cells except These are the only epidermal cells that contain chloroplastsGuard cells can undergo rapid turgor changesThe opening and closing of the stomatal pore is a function of guard cellsTheir outer and lateral walls are comparatively thicker than inner wall

The guard cell is surrounded by epidermal cell.TrueFalse

What do the guard cells in the dermal tissue of a plant do?A.Control the passage of carbon dioxide, oxygen, and water vaporB.Form a hard covering that turns into lignin and woodC.Allow the plant to move in response to sunlightD.Extend into the soil and increase the surface area of the rootSUBMITarrow_backPREVIOUS

Examine the slides of the “monocot and dicot epidermis” (#68). This surface view of the epidermis shows that most epidermis cells are fairly undifferentiated (parenchyma) without chloroplasts. The shapes and walls of epidermis cells may be used in some instances to identify the plant to genus or family. Find the stomates and their guard cells. The guard cells have chloroplasts and pick up the stain. Do both specimens have obvious subsidiary cells around their guard cells?

What are the functions of stomata and guard cells, and what would happen to a plant if these cells did not function correctly?Group of answer choicesStomata allow gases to enter and exit the plant. Guard cells regulate the opening and closing of stomata. Photosynthesis and, in turn, transpiration, would not occur which is necessary to maintain a continuous flow of water upwards from the roots to the leaves.Guard cells allow carbon dioxide to enter and exit the plant. Stomata regulate the opening and closing of guard cells. Transpiration and in turn, photosynthesis would not occur which is necessary to maintain a continuous flow of water upwards from the roots to the leaves.Stomata allow oxygen to enter and exit the plant. Guard cells regulate the opening and closing of stomata. If the cells didn’t function, photosynthesis would continue but transpiration would cease, which would interfere with the necessary continuous flow of water upward from roots to leaves.Guard cells allow carbon dioxide to enter and exit the plant. Stomata regulate the opening and closing of guard cells. If the cells didn’t function, photosynthesis and transpiration would cease, which would interfere with the necessary continuous flow of water upward from roots to leaves.

The figure represents two guard cells, with surrounding epidermal cells, in the leaf of a plant. The plant is in bright light. The arrows on the diagram indicate the direction of the net movement of water from the epidermal cells into the guard cells.In this situationAthe stomatal pore will decrease in diameter.Bphotosynthesis will decrease in the guard cells.Cthe rate of water movement in the vascular tissue of the plant will decrease.Dthe concentration of solutes within the guard cells is greater than in the surrounding epidermal cells.
