True / False Questions
42. The stem growing tip is nestled within the cotyledons and is pulled through the soil in a
germinating bean seed (dicot) whereas the coleoptile surrounds the growing tip in germinating
corn (monocot) seeds. Both strategies protect the delicate growing tip.
43. The life cycle of flowering plants begins with seed germination and ends with a mature
plant producing new seeds.
