Which of the following is the correct sequence for the germination of the eudicot seed?
Select one: a. The two cotyledons have absorbed the endosperm and supply the nutrients to the embryo. As the embryo emerges, from the soil it consumes the nutrients and develops the shoot. The hypocotyl becomes part of the stem and the radicle develops into the roots. b. The cotyledon was absorbed by the endosperm and supplies the nutrients to the embryo. As the embryo emerges from the soil, it consumes the nutrients and develops the shoot. The hypocotyl becomes part of the stem and the radicle develops into the roots. c. The two cotyledons have absorbed the endosperm and supply the nutrients to the embryo. As the embryo emerges from the soil, it consumes the nutrients and develops the shoot. The radicle becomes part of the stem and the hypocotyl develops into the roots. d. The pericarp has absorbed the endosperm and supplies the nutrients to the embryo. As the embryo emerges from the soil, it consumes the nutrients and develops the shoot. The hypocotyl becomes part of the stem and the radicle develops into the roots. e. The two cotyledons have absorbed the endosperm and supply the nutrients to the embryo. As the embryo emerges from the soil, it consumes the nutrients and develops the shoot. The plumule and the radicle push through the coleorhiza during germination.
