BIOL 1202 – 60 Exam Questions on Plant Structure, Roots, Leaves & Tissues – 2025/2026 – Louisiana State University

This document contains 60 verified multiple-choice questions and answers for BIOL 1202 Exam 3 at Louisiana State University, for the academic year 2025/2026. It is focused on core concepts in plant anatomy and physiology, making it ideal for students preparing for plant biology or botany exams. Topics include the three major plant organ systems—roots, stems, and leaves—and their specialized forms and functions. Students are tested on key processes such as nutrient absorption, photosynthesis, storage, and support across various plant structures. The material thoroughly covers specialized roots (e.g., prop roots, storage roots, pneumatophores), stem modifications (e.g., stolons, rhizomes, tubers), and leaf types (simple vs. compound) along with their respective functions. It also explains tissue systems in plants—dermal (epidermis, periderm), vascular (xylem, phloem), and ground tissue—and the roles of specific plant cell types like parenchyma, collenchyma, and sclerenchyma. Additional focus is given to cell maturity status, structural adaptations (spines, tendrils, reproductive leaves), and transport cells such as tracheids, vessel elements, and sieve-tube members. This resource is perfect for undergraduate biology or botany students needing to review structural plant biology and its physiological applications.
