Plant Physiology

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

Absorption By Roots

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

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.

Transpiration

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

Explanation

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

Types Of Transpiration

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

Significance

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

Factors Affecting Transpiration

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

Example

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

Photosynthesis

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

Explanation

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

Conditions Required

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

Site

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

Importance

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

Chemical Coordination In Plants

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

Explanation

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

Types Of Plant Hormones

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