Sample questions

1. 1.In a monocotyledonous (grass) embryo, which pair correctly describes the coleoptile and coleorrhiza?
   • A.Coleoptile encloses the shoot apex and leaf primordia; coleorrhiza encloses the radicle and root cap
   • B.Coleoptile encloses the radicle; coleorrhiza encloses the shoot apex
   • C.Both enclose the radicle and root cap
   • D.Coleoptile is the cotyledon; coleorrhiza is the scutellum
2. 2.The tallest flower, whose floral reward is providing a safe place to lay eggs, is about 6 feet in height and belongs to:
   • A.Amorphophallus
   • B.Yucca

   • B.It produces seeds without fertilisation
   • C.It always requires the fusion of two male gametes with the egg and polar nuclei
   • D.In some species a diploid egg cell forms without reduction division and develops into the embryo
4. 4.In monosporic development of the female gametophyte, a single megaspore mother cell finally gives rise to a mature embryo sac. How many meiotic divisions, surviving megaspores, and free-nuclear mitotic divisions (after the functional megaspore) are involved, respectively?
   • A.1 meiosis, 1 functional megaspore, 3 mitotic divisions
   • B.2 meioses, 4 functional megaspores, 3 mitotic divisions
   • C.1 meiosis, 4 functional megaspores, 2 mitotic divisions
