Plant hormones (phytohormones) are the chemical molecules produced by plant tissues in extremely low concentrations for assisting cardinal functions like flowering, fruit ripening, photo periodism, and stress relief. They also help in sex determination of the flowers produced by the plant. There are five major phytohormones, which are auxin, gibberellin, cytokinine, abscicic acid and ethylene. Each of these also has their own characteristic functions.

Summary Introduction

Concept introduction: Plant hormones (phytohormones) are the chemical molecules produced by plant tissues in extremely low concentrations for assisting cardinal functions like flowering, fruit ripening, photo periodism, and stress relief. They also help in sex determination of the flowers produced by the plant. There are five major phytohormones, which are auxin, gibberellin, cytokinine, abscicic acid and ethylene. Each of these also has their own characteristic functions.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: Plant hormones are active in adult plants with different effects in different tissues that often have multiple, overlapping effects especially for developing plant embryos. Therefore, option e. is correct.

Explanation of Solution

Reason for correct answer: Plant hormones are chemical molecules that do many cardinal roles in the plant body. They have different functions in different tissues of adult plants. Many plant hormones have multiple and overlapping effects that are very essential for the growth and development of the plant.

Option e. is given as “all of the above”. Since plant hormones have many important functions in the adult plant body, they have different functions in different tissues especially for developing the plant embryo. Therefore, option e. is correct.

Reasons for incorrect answer:

Option a. is given as “often have multiple, overlapping effects”. Plant hormones are the chemical compounds produced by the plant body. Other than multiple effects, they are only functional in adult plants. Moreover, they do different functions in different tissues especially in developing the plant embryo. Therefore, option a. is incorrect.

Option b. is given as “are active in developing plant embryos”. Plant hormones are chemical compounds produced by the adult plant body. They are very active for developing the plant embryo. Moreover, they do different effects in different plant tissues with multiple or overlapping functions. Therefore, option b. is incorrect.

Option c. is given as “are active in adult plants”. Plant hormones have multiple effects on different tissues of an adult plant body especially for developing the plant embryo. Therefore, option c. is incorrect.

Option d. is given as “may have different effects in different tissues”. Plant hormones have different effects in different tissues. They are very active for developing the plant embryos of adult plants. Therefore, option d. is incorrect.

Hence, options a., b., c., and d. are incorrect.

Conclusion

Plant hormones or phytohormones are the chemical compounds produced by the adult plant body with multiple or overlapping effect on different tissues especially for developing the plant embryos.
