Botany - Sexual Reproduction in Flowering Plants Question with Solution | TestHub

The seed which store food materials in endosperm are called endospermic or albuminous seed. Cotyledon is the seed leaf within the embryo of a seed. These stored nutrients are supplied to the seedling during germination. Upon germination, the hypocotyl pushes the cotyledons above the ground to develop. It eventually becomes part of the plant stem, while radicle forms roots. Perisperm is the remnant of nucellus which are persistent. It surrounds, stores food and provide nourishment to the embryo in an angiosperm seed. It is diploid in nature. Related Theory The cotyledon is described as a seed leaf that stores food in the form of starch and protein for use by the embryo. An embryo of a monocotyledon (monocot) plant has one cotyledon, while that of a dicotyledon (dicot) plant has two cotyledons. A monocot stores the bulk of its energy in the endosperm.
