Summary Introduction

Introduction:

The plant hormones can be defined as certain chemicals that are responsible for triggering some responses within the body of the plant. These hormones cause the response to gravity, light or touch. These hormones also give quick responses to stimuli.

Expert Solution & Answer

Answer to Problem 1TY

The correct option is (c).auxin, cytokinin, gibberellin

Explanation of Solution

Explanation/justification for the correct answer:

The option is (c) auxin, cytokinin, gibberellin

The hormones auxins, cytokinins, and gibberellins are called plant hormones. Auxin is responsible for growth, cytokinins are responsible for cell division and gibberellins are responsible for stimulating cell division.

Explanation of incorrect answer:

Option (a) cyclic AMP, IP₃ and calcium ions.

The ions cyclic AMP, IP₃_, and calcium ions are called as secondary messengers and are found in animal and plant cells. These are responsible for the transmission of messages from a different type of receptors and hormones. Hence option (a) is incorrect.

Option (b) calcium, CPDKs, and DELLA proteins

The calcium, CPDKs, and DELLA are called proteins. The CPDK called as effector, influences cellular response like closing and opening of ion channels. The protein DELLA is responsible for restricting the cell division process when gibberellin hormones are present. These are not hormones. Hence, option (b) is incorrect.

Option (d) chlorophyll, carotenoids, and phytochrome

Chlorophyll is the green pigment in a plant that helps in photosynthesis. Carotenoids are responsible for yellow, orange and red. Phytochromes are photoreceptors in plants that detect light. As these are not hormones, the answer is incorrect.

Option ( e) statoliths, pulvini, and parenchyma

Statoliths are plastids present in root cells. Pulvini help in response quick touch. The parenchyma tissue transfers oxygen into shoots and roots. As this is not hormones, option (e) is incorrect.

Conclusion

The major type of plant hormones includes auxin, cytokinins, and gibberellins hormones. Auxin helps in growth and the behavior of the plant. On the other hand, cytokinins and gibberellins and responsible for the promotion of cell division and aging and stimulation of cell division, elongation respectively. Hence, the option (c) is correct.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
