Question
Chapter 29, Problem 8TY
Summary Introduction
Introduction:
There are some different ways in which plants defend themselves from the pathogens and diseases. The binding of elicitors is a resistance by the plants by creating certain molecules. These molecules are present at the cell membrane of the plant and keep the elicitor from attaching the plant.

- Plant cells communicate in a variety of ways to elicit cellular responses. In the figure below the plant is responding the presence of light with the release of auxin. Auxin was first discovered for its ability to promote growth in plants. It is a plant hormone that inhibits the lengthening and stimulate the formation of lateral roots and root hairs. a) Describe the plant’s response to the presence of light.

Homeostasisarrow_forwardWhich of the following does auxin cause in the tropism with which it is involved? increased protein synthesis increased plasma membrane permeability hardening of cell walls cell elongation rapid cell divisionarrow_forward
- A house plant that has been placed in the window will grow toward the source of light. Which option is the best possible reason? auxin becomes less concentrated on the illuminated side of the plant auxin becomes more concentrated in the roots of the plant auxin is produced only when the sun shines auxin inhibits the growth of cells on the shady side, so the cells on the sunny side grow faster auxin becomes more concentrated on the illuminated side of the plantarrow_forwardWhich hormone can regulate guard cells?

- • On a commercial scale, enhancing the level of _______ (hormone) can help to speed up fruit ripening. • What measure do fruit producers take to slow down fruit ripening that is caused by natural ethylene?• What is a ‘triple response’. Which plant hormone initiates a triple response? • A change in the ratio of ethylene to auxin controls abscission. In the autumn, the amount of __________ decreases, rendering the cells of the abscission layer more sensitive to __________.arrow_forwardExperiments show that plants can communicate with each other. Consider a plant put under drought conditions which is connected via the roots to a neighboring plant. The drought plantbsends messages through the roots to its neighbor. Even through the neighbor plant has plenty of water, it will respond as if in drought conditions too. In what way will the plant respond?arrow_forwardPlant cells communicate in a variety of ways to elicit cellular responses.
