Question
Chapter 39, Problem 3S
Summary Introduction
To explain:
The way through which the sites receiving the signal may vary during the course of growth when the systemin get transported through the phloem of the tomato plant.
Introduction:
The wound response in plants occurs when the leaf gets injured or chewed by the invader. During such responses, there is a rapid synthesis and release of proteinase inhibitor. Such type of inhibitors is only synthesized in conditions when the plant is wounded.

at cellular level?
What are the benefits for the tobacco plant that has developed systemic acquired
resistance (SAR) in comparison to HR?

The summer is not optimal for grape growing and you're searching in your memory for something regarding plant hormones.
Explain 2 ways you could utilize plant hormones (choose from auxin, ethylene, cytokinin, gibberellin, abscisic acid, salicylic acid, jasonic acid) to compensate for a problem during growing. For each way:
It is the term referring to the characteristic leaf structure of C4 plants that enables them to outperform C3 plants in an environment that has high O2 concentration and/or temperature. Unlike C3 and CAM plants, C4 plants, such as corn and sugarcane, have leaves with vascular bundles that are surrounded by a chloroplast-rich vascular bundle sheath, which is further surrounded by the spongy mesophyll.

Chemical signals called play an important role in a plant's ability to respond to a stimulus. These signals bind to receptors, the first step in a cellular response called a may be located in the plasma membrane, the cytoplasm, the nucleus, or the endoplasmic reticulum. The series of relay proteins or enzymes activated by the hormone binding the receptor make up the Some responses are immediate, while others require a like Ca*, to initiate a cellular response.
