POB Final Exam Biology Study Guide | 2025/2026 with 200+ Verified Q&As | Plant Structures, Animal Phyla, Genetics, Behavior & Ecology | University of Arkansas

This POB (Principles of Biology) Final Exam Study Guide for the 2025/2026 academic year is a fully verified and A+-graded exam resource developed to support undergraduate biology students at the University of Arkansas and similar programs. It features 200+ exam-focused questions and answers covering every major topic from plant biology to evolutionary ecology—making it an essential tool for high-scoring final exam preparation. The guide offers detailed coverage of: Plant biology: Anatomy of flowers (stamens, carpels, petals, sepals), pollination and fertilization, life cycles (sporophyte and gametophyte), seed plant structures, gymnosperms and angiosperms, mosses, and ferns. Animal diversity and structure: Invertebrate and vertebrate characteristics, body symmetry, digestive systems, chordate evolution, flatworms, mollusks, annelids, arthropods, echinoderms, and all major phyla. Genetics and cellular biology: Reproduction (sexual and asexual), meiosis and mitosis, DNA, chromosomes, trait inheritance (dominant vs. recessive), and examples of gene-driven behavior (e.g., fosB gene). Human biology and physiology: Major body systems (nervous, circulatory, skeletal, muscular), homeostasis, and classifications of mammals (monotremes, marsupials, placental). Animal behavior and learning: Innate vs. learned behavior, imprinting, operant/classical conditioning, fixed action patterns, social structures, kin selection, sexual selection, and altruism. Ecology and environmental biology: Energy flow, biogeochemical cycles, types of survivorship, population dynamics, interspecies interactions (mutualism, parasitism, predation), and ecosystem structure. This guide is perfect for: University of Arkansas students in Principles of Biology courses Pre-med, pre-vet, zoology, botany, and life sciences majors Students preparing for final exams, quizzes, or lab practicals Anyone needing a broad, reliable biology refresher for standardized testing or academic review With clear, concise explanations, biological terminology, and accurate definitions, this study tool ensures high comprehension and retention, preparing students for both theoretical and applied exam questions.
