BIOLOGY LESSON NOTE ON CROP PROPAGATION

Image
Topic: Crop Propagation Class: Senior Secondary School 2 (SS2) Subject: Biology Specific Objectives By the end of this lesson, students should be able to: Define crop propagation. Differentiate between sexual and asexual propagation. Identify and explain various methods of crop propagation. Highlight the advantages and disadvantages of each method. Recognize common examples of crops propagated using each method. Lesson Content 1. Meaning of Crop Propagation Crop propagation refers to the process by which plants reproduce or are reproduced to give rise to new plants. This can occur naturally or be carried out artificially by farmers or agricultural scientists. It is a vital practice in agriculture that ensures the continuous production of food and other plant-based resources. 2. Types of Crop Propagation Crop propagation is broadly categorized into two main types: Sexual Propagation (Seed Propagation) Asexual Propagation (Vegetative Propagation) 3. Sexual Propa...

LESSON NOTE ON BIOLOGY OF HEREDITY

TOPIC: BIOLOGY OF HEREDITY   DEFINITION OF HEREDITY  Heredity is the passing down of traits from one generation to the other. It is the reason why children have similar physical and behavioral traits as their parents and grandparents. It is crucial in the study of genetics, biology, and evolution. TRANSMISSION AND EXPRESSION OF CHARACTER IN ORGANISM The transmission and expression of characters in an organism takes place through the genetic material, which is the DNA. DNA contains genes that code for specific traits such as eye color, height, and hair texture. The genes are located on the chromosomes, which are thread-like structures found in the nucleus of a cell. The expression of these genes occurs through the process of transcription and translation, where the genes are turned into proteins. DEFINITION OF GENETIC VARIATION  Genetic variation refers to the differences that occur between individuals of the same species. It is brought about by mutations that alter the DN...
