The following are notable examples, categorized by their types and key attributes: Forage Legumes Many legumes are cultivated specifically for forage or green manuring rather than human consumption. These include: Examples of Tree Legumes Tree legumes … Read more
What are Cereals? Cereals are among the most vital sources of plant-based food for humans and animals. They have held this significance since ancient times, with their cultivation dating back so far that their wild ancestors are no longer recognizable. Over centuries, numerous species and varieties have been developed, even before recorded history. The ancient … Read more
What is Centers of origin? The concept of “centers of origin” refers to the geographical regions where specific groups of organisms, whether wild or domesticated, initially emerged on Earth. This term is often associated with the origins of crop plants and wild species, reflecting the places where these organisms first evolved. It is important to … Read more
What are Prions? Definition of Prion A prion is an infectious, misfolded protein that causes neurodegenerative diseases by inducing abnormal folding of normal cellular proteins, leading to the accumulation of these misfolded proteins in the brain. Unlike other infectious agents, prions lack nucleic acids and propagate their abnormal structure through direct protein-protein interactions. Characteristics of … Read more
Water absorption is a critical physiological process in plants, essential for their growth and various metabolic activities. In lower plants, such as algae and mosses, water absorption occurs across the entire plant surface through the process of osmosis. However, in higher plants, this function is specialized and occurs primarily through the root hairs. The primary … Read more
What is Plant growth regulator? Types of Plant Growth There are several distinct types of plant growth, each characterized by specific processes and outcomes. These growth types define how plants develop in size, form, and function throughout their life cycle. Below is a detailed breakdown of the main types of plant growth: Factors Affecting Plant … Read more
What is Photomorphogenesis? Definition of Photomorphogenesis Photomorphogenesis is the process by which plants use light as a signal to regulate growth and development, influencing stages such as seed germination, seedling growth, and flowering. Photoreceptors and Photomorphogenesis Photomorphogenesis in plants is regulated by specialized light-sensitive molecules known as photoreceptors. These photoreceptors are crucial for interpreting light signals … Read more
What is Vernalization? Definition of Vernalization Vernalization is the process by which exposure to prolonged cold temperatures induces flowering in plants, ensuring they bloom in favorable conditions, typically after winter. Types of Vernalization Vernalization can be categorized into two primary types, each influencing flowering in distinct ways: Mechanism of Vernalization Vernalization involves a series of … Read more
What is Photoperiodism? Classification of plants based on Photoperiodism Plants are classified into several categories based on their response to the length of light and dark periods. These categories reflect how different species time their flowering and growth in accordance with seasonal day-length variations. The primary classifications include: Photoperiodic Induction Photoperiodic induction refers to the … Read more
What is Phytochrome? Structure of Phytochrome Phytochrome is a complex protein pigment that plays a crucial role in plant photoreception and signaling. Here are the key aspects of its structure: Types of Phytochrome Phytochromes are classified into different types based on their genetic encoding and functional roles in plants. The main types of phytochrome include: … Read more
