Which of the following is not a function of proteins present in theplasma membrane?a. Proteins assist the passage of materials into the cell.b. Proteins interact with and recognize other cells.c. Proteins bind with specific hormones.d. Proteins carry out specific metabolic reactions.e. Proteins produce lipid molecules.
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. (refer to picture)
Signal transduction pathways benefit cells for all of the following reasons except :
a.
they enable different cells to respond appropriately to the same signal.
b.
they can amplify and diversify a signal.
c.
they help cells use up phosphate generated by ATP breakdown.
d.
they help cells respond to signal molecules that are too large or too polar to cross the plasma membrane

- Consider a plant that is exposed to extreme cold temperatures. Do the cells of this plant manipulate the composition of their membranes in response to this environmental stress?If not, explain why the plant does not manipulate membrane composition in response to this stress.If so, explain the specific changes that these cells would carry out in response to this environmental stress.arrow_forwardA tobacco plant has successfully fended off plant pathogen via hypersensitive response (HR). (i) What would you be able to observe on the plant and explain the processes that happened at cellular level? What are the benefits for the tobacco plant that has developed systemic acquired resistance (SAR) in comparison to HR? (ii) (ii) Name the chemical compounds responsible in triggering SAR and how would this signal be transmitted?arrow_forwardMany common medications function by interrupting the normal operation of certain signal transduction pathways. Which of the following describes a possible mechanism by which a certain medication may interrupt a signal transduction pathway? A A medication enters the target cell and triggers apoptosis by causing the release of di- gestive enzymes from cell lysosomes. B A medication interacts with the phospholipid bi-layer of the cell membrane and in- creases its permeability. с D A medication binds to membrane-bound glucose proteins and acts as an allosteric in- hibitor that prevents the intake of glucose by the cell. A medication diffuses through the membrane of a target cell and inhibits an enzyme that normally synthesizes a second messenger.arrow_forward
- In farming communities, there is a concern that over irrigation can leech nutrients out of the soil, flood a farm area, and add salt to the soil in a process called salinization. The overall negative results are that some plants cannot germinate (grow from seed) and other adult or growing plants will die. Explain what is happening on the cell level, in regards to transport across the cell membrane, why seeds might not germinate, and why adult plants might die.arrow_forwardWhich hormone can regulate guard cells?

- Detection of external signals by plant cells often results in a transient rise in the concentration of Ca2+ ions in the cytoplasm. What transport processes can cause such an increase in cytoplasmic Ca2+, and what transport processes can remove the excess Ca2+ and restore the level of Ca2+ to its resting state?arrow_forwardPlant cells communicate in a variety of ways to elicit cellular responses.
