Question
Chapter 37.2, Problem 2EQ
Summary Introduction
To determine: Whether four seedling tips are enough to conclude the general response of such seedling tips in the experiments performed or not.
Introduction: An organism’s response to an external or an internal stimulus is known as its behavior. Plant movement is one of the examples of plant behavior. Chemical signals which are transported within the body of a plant are known as plant hormones. Some of the examples of plant hormones are auxins, cytokinins, gibberellins, ethylene, abscisic acid, and brassinosteroids.

In the experiment conducted to test why individuals in the tree species Fuschsia excorticata retain flowers after they turn red even though the trees pollinate and offer a nectar reward only when flowers are green (Figure attached 10.28 first tested the 'pollinator-attraction' hypothesis that red flowers attract pollinators: once drawn to a tree, pollinators could forage on the green flowers still present, increasing overall pollination efficiency. Please assess the lowercase-Roman-numeral-labelled statements that appear immediately below and click the uppercase-letter-labelled response that appears below and conveys the most accurate information.
i. If the pollinator-attraction hypothesis were correct, then green flowers surrounded by red flowers should receive more pollen than should green flowers surrounded by only green flowers.
ii. The prediction in statement i could be tested by removing red flowers from some trees, forming one experimental group, and leaving red flowers on…
Your concept map must include details about the following topics: types of stimuli plants respond to, 3 stages of cell signaling, 6 major plant hormones Six main types: Auxins, abscisic acid, cytokinins, ethylene gibberellin, and brassinosteroids. and their functions, phytochrome, plant responses to light, statocytes, statoliths, plant responses to gravity, plant responses to touch, plant defenses against herbivores, plant defenses against pathogens (hypersensitive response and systemic acquired resistance)
Using the provided figure, describe the importance of the two phytochrome systems in controlling de-etiolation and green stem elongation under full sun and shade. Include the key mechanisms and temporal changes in control of this process.
