The Grade 12 Biology curriculum offers a comprehensive and diverse exploration divided into ten units. Commencing with Unit 1, “Plant Anatomy,” the study encompasses the intricacies of plant tissues, their types, and the arrangement of angiosperms in roots, stems, and leaves. Unit 2, “Plant Physiology,” delves into the fascinating world of water relations, photosynthesis, respiration, plant hormones, and plant growth and movement.
Unit 3, “Genetics,” provides a foundational introduction to the structure and function of DNA and RNA, along with the intricate process of DNA replication. Unit 4, “Embryology,” explores both sexual and asexual reproduction in angiosperms. Unit 5, “Biotechnology,” delves into the multifaceted applications of biotechnology in plant tissue culture, plant breeding, disease-resistant plant development, molecular genetics, and the groundbreaking CRISPR-Cas9 technology. Unit 6, “Animal Tissue,” thoroughly discusses the four main types of animal tissues: epithelial, connective, muscular, and nervous tissue.
Unit 7, “Developmental Biology,” provides insights into the structure and formation of spermatozoa and ovum, a process known as gametogenesis. Unit 8, “Human Biology,” encompasses a comprehensive discussion of all aspects related to human biology. Unit 9, “Human Population and Health Disorders,” delves into the dynamics of human population growth, its effects, and measures for its control. Unit 10, “Applied Biology,” emphasizes critical topics such as tissue and organ transplantation, in-vitro fertilization, amniocentesis, and the fascinating world of genetically modified organisms. Throughout this educational journey, students gain a profound understanding of life’s intricacies and the vital importance of safeguarding it.
