Growth and differentiation in plants

Course Description: This course covers the biological processes related to plant growth, differentiation, and development, with a focus on different growth zones and stages, as well as analyzing growth curves, rates, and influencing factors. The course also focuses on the study of plant hormones (phytohormones) and their role in regulating growth and development. Growth-promoting hormones such as auxins, gibberellins, and cytokinins will be discussed in terms of their discovery, biosynthesis, production sites, transport mechanisms, and physiological effects on plants. The course also includes the study of growth inhibitors such as abscisic acid and ethylene, analyzing their properties, functions, and role in regulating various biological processes. The course also covers physiological phenomena related to growth, such as dormancy, photoperiodism, bud formation, and the effect of environmental factors, by linking theoretical concepts to practical applications through the interpretation and analysis of scientific experiment results.
Credit hours: 3
Prerequisites: 260 BIO

Additional information:

This course contributes to preparing students for the job market by providing them with a scientific foundation in understanding plant growth, differentiation, and the applications of plant hormones, a field of increasing importance in many sectors, such as:

 

The agricultural sector and plant production: improving crop growth and increasing productivity using plant growth regulators.
Fertilizer Companies and Growth Regulators: Evaluating Plant Hormone Efficacy and Applications in Improving Crop Quality.
Agricultural Research Centers: A Study of the Effect of Environmental and Hormonal Factors on Plant Growth and Development.
Plant biotechnology: Developing modern strategies for controlling plant growth and improving desirable traits.
Nurseries and Greenhouse Management: Controlling germination, budding, and flowering according to suitable environmental conditions.

The course develops skills in scientific analysis, interpretation of experimental results, and evaluation of the impact of different factors on plant growth, which are skills required in the fields of agriculture, scientific research, and biotechnology.
