Plant Growth and Development

This topic deals with the growth of plants which explains that growth is indeterminate and measurable. We will also study the phases of growth with the growth rates and conditions for growth.

This topic describes differentiation and their effects on plant growth. A brief note on dedifferentiation and redifferentiation are also given here.

The topic discusses the plant growth regulators as the small, simple molecules of diverse chemical composition. It also describes the physiological effects of plant growth regulators.

This topic helps us understand the process of seed germination and highlights some conditions necessary for seed germination. It also discusses some external and internal factors that affect seed germination.

In this topic, we will learn the process of development in a plant from germination of a seed to senescence. It highlights the phenomenon of senescence with the aid of examples. A brief note on abscission is also given here.

In this topic, we will learn about linkage maps and explains the measurement in terms of map units. It also explains the cross over in different generations with the aid of gamete crossing table.

This topic sheds light on phytochromes which is a class of photoreceptor in plants. It details the types of phytochromes and the wavelength of these phytochromes.

In this topic, we will discuss Photoperiodism as the response of plants to periods of day and night. This describes the effects of day and night in plants.

The topic discusses vernalisation as the promotion of flowering by a period of low temperature. It also includes some examples of vernalisation.
