Summary Introduction
Introduction:
Auxin is the plant hormone that is responsible for promoting the coleoptiles elongation. They even have various other functions in the flowering plants. Natural auxin is called as IAA (indoleacetic acid).

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)
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.
A 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?

- 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_forwardall the option are the same as shownarrow_forwardDetection 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_forward

- Adjacent plant cells have narrow channels called plasmodesmata that pass through the cell walls of the connected cells. Which of the following statements best describes a primary function of plasmodesmata? A B с D They eliminate the need for cells to have receptors for signaling molecules. They eliminate the need to produce signaling molecules. They decrease the energy requirements for active transport. They allow the movement of nutrients and signaling molecules across adjacent cells.arrow_forwardYou wanted to prepare a fish dish for your grandfather that he loves the dried salted Codfish. But you noticed that this might be causing a problem for your elder grandfather since he has hypertension, what would you do to remove the salt from the fish? (Answer with one word) What is the mechanism by which the salt gets out from the fish? (one word) * Please put a comma and space between the two answers word.

Answer:arrow_forwardWhat did Went's experiments with the gelatin block demonstrate? A. Plants cannot be induced to bend during growth unless they are exposed to an indirect source of light. B. Light induces the coleoptile to produce a diffusible substance that moves to the growing region of a plant where it stimulates cells to elongate. C. Gelatin can enhance the movement of a soluble factor from the growing region of a plant to the coleoptile where it accelerates growth. D. When a plant tip is removed from a growing plant, the plant acquires the ability to bend toward the lightarrow_forward
