Plant Anatomy & Morphology Pioneers — NEET Biology
📚 Practice ConceptWhen Katherine Esau died in the year 1997, Peter Raven, director of Anatomy and Morphology, Missouri Botanical Garden, remembered that she 'absolutely dominated' the field of plant biology even at the age of 99.
Consider the following statements: 1. Early descriptions of life forms were based only on gross structural features and perceivable living phenomena. 2. Before physiology was established, biology was mainly studied as natural history. 3. Katherine Esau demonstrated that curly top virus spreads through xylem tissue. 4. All angiosperms, despite large diversity, are characterised by the presence of roots, stems, leaves, flowers, and fruits. 5. Adaptations in plants may include modifications for habitats, protection, climbing, and storage. Which of the above statements are correct?
View solution & NCERT explanation
Correct answer: A — 1, 2 and 3
Statement 1 is correct – NCERT states that descriptions were based on gross structural features and observable phenomena. Statement 2 is correct – before physiology, biology remained natural history. Statement 3 is incorrect – Katherine Esau reported curly top virus spreads via phloem, not xylem. Statement 4 is correct – despite morphological diversity, angiosperms are characterised by roots, stems, leaves, flowers, and fruits. Statement 5 is correct – NCERT mentions adaptations for various habitats, protection, climbing, and storage. Thus, the correct set is 1, 2, 4, 5.
