22. The evolution of double fertilization is a unique characteristic of: Angiosperms
23. The evolution of the cuticle on plant surfaces was an adaptation to: Prevent desiccation on land
24. The evolution of flowers and fruits in Angiosperms is thought to have led to: More efficient dispersal and pollination mechanisms
25. Pollination in Gymnosperms primarily occurs via: Wind
26. The classification of plants into divisions (or phyla) is based on major differences in:
27. Which of the following is a characteristic feature of Monocotyledons? Vascular bundles scattered in the stem
28. The classification of plants into kingdoms, divisions, classes, orders, families, genera, and species follows a hierarchical structure known as: Linnaean Taxonomy
29. Angiosperms are divided into two main classes based on the number of cotyledons. These are: Monocots and Dicots
30. The term 'endosperm' refers to nutritive tissue found in the seeds of: Angiosperms
31. Which of the following is an example of a Bryophyte? Sphagnum moss
32. The development of alternation of generations is a significant feature in the life cycle of which plant groups? Bryophytes, Pteridophytes, Gymnosperms, and Angiosperms
33. The structure that contains the male gametes in seed plants is called the: Pollen grain
34. Which characteristic is typical of dicotyledonous plants? Taproot system

47. Which of the following is NOT a characteristic of algae? They possess true roots, stems, and leaves.
48. Which of the following is a key characteristic of Pteridophytes (ferns)? They have well-developed vascular tissues but lack flowers and seeds.
49. What is the primary role of the sporophyte generation in Bryophytes? To produce spores
