Neco Model Questions Vol1 2018 Biology Question 33

Consider the following simplified dichotomous key for classifying a plant specimen:\n\n1a. Plant lacks vascular tissue ………> Algae\n1b. Plant possesses vascular tissue ………> go to 2\n\n2a. Plant does not produce seeds ………> go to 3\n2b. Plant produces seeds ………> go to 4\n\n3a. Plant is small, lacks true roots, and reproduces via spores ………> Bryophytes (mosses)\n3b. Plant has true roots and reproduces via spores ………> Pteridophytes (ferns)\n\n4a. Plant produces flowers ………> Angiosperms\n4b. Plant does not produce flowers ………> go to 5\n\n5a. Plant bears cones and has needle‑like leaves ………> Gymnosperms (conifers)\n5b. Plant bears cones but has broad leaves ………> other Gymnosperms\n\nAn unknown plant specimen exhibits the following characteristics: it possesses vascular tissue, produces seeds, does not bear flowers, bears cones, and has needle‑like leaves. Using the key, determine the hierarchical classification of the specimen down to the class level (i.e., Kingdom, Division/Phylum, Class).
