    Plant Physiology

    This section covers the essential processes of plant physiology, including absorption by roots, transpiration, photosynthesis, and chemical coordination through hormones.

    Learning Practice

  • 2.1

    Absorption By Roots

    Roots absorb water and minerals from the soil through various processes, significantly aided by structures like root hairs.

    Learning Practice

  • 2.1.2

    Processes Involved

    This section discusses the major processes involved in the absorption of water and minerals by plant roots, including imbibition, osmosis, active transport, and root pressure.

    Learning Practice

  • 2.2

    Transpiration

    Transpiration is the process through which plants lose water vapor primarily from their leaves, helping with cooling and nutrient transport.

    Learning Practice

  • 2.2.1

    Explanation

    Transpiration is the process of water vapor loss from plants, primarily through leaves, affecting their cooling and nutrient absorption.

    Learning Practice

  • 2.2.2

    Types Of Transpiration

    This section discusses the various types of transpiration in plants, emphasizing their importance and the factors that affect the transpiration process.

    Learning Practice

  • 2.2.3

    Significance

    The significance of transpiration in plants encompasses its roles in cooling, water absorption, and mineral transport.

    Learning Practice

  • 2.2.4

    Factors Affecting Transpiration

    Factors such as light, temperature, humidity, and wind significantly influence transpiration in plants.

    Learning Practice

  • 2.2.5

    Example

    This section illustrates key concepts of plant physiology through practical examples.

    Learning Practice

  • 2.3

    Photosynthesis

    Photosynthesis is the crucial process by which green plants synthesize food using sunlight, carbon dioxide, and water, releasing oxygen as a byproduct.

    Learning Practice

  • 2.3.1

    Explanation

    Photosynthesis is the process by which green plants convert sunlight, carbon dioxide, and water into glucose and oxygen.

    Learning Practice

  • 2.3.2

    Conditions Required

    This section covers the essential conditions required for photosynthesis, highlighting the role of sunlight, chlorophyll, carbon dioxide, and water.

    Learning Practice

  • 2.3.3

    Site

    In this section, the site of photosynthesis is identified as the chloroplasts in leaf cells, where light energy is converted into chemical energy.

    Learning Practice

  • 2.3.4

    Importance

    The importance of photosynthesis lies in its role as the primary source of energy for nearly all life forms on Earth.

    Learning Practice

  • 2.4

    Chemical Coordination In Plants

    Chemical coordination in plants is governed by hormones that regulate growth and responses to environmental stimuli.

    Learning Practice

  • 2.4.1

    Explanation

    This section covers chemical coordination in plants, focusing on the role of plant hormones in regulating growth and response to stimuli.

    Learning Practice

  • 2.4.2

    Types Of Plant Hormones

    This section covers the types of plant hormones and their respective functions in regulating plant growth and development.
