Genetic analysis of early embryo development in a variety of vascular plants may be the only way to conclusively determine the evolutionary origin of the distinctive difference between monocot and dicot embryos.doi:10.1007/BF02857623William C. Burger...
What is a monocot in plants? Cotyledons are known as seed leaves since they are part of a plant's embryo and seed. They are the plant's first leaves to germinate, although they are not true leaves. What is the difference between a monocot and a dicot? Monocotyledons have one seed, fl...
(Botany) any flowering plant of the classMonocotyledonae,having a single embryonic seed leaf, leaves with parallel veins, and flowers with parts in threes: includes grasses, lilies, palms, and orchids. Often shortened to:monocotComparedicotyledon ...

Supplement Botany: Inplants, the cotyledons are involved in the storage or absorption of food reserves. The number of cotyledons is one of the plant characteristics used in groupingangiosperms intomonocots anddicots. Anatomy: In humans, a full term placenta contains about 20 cotyledons that are ...

less completely surrounded by a sheath of sclerenchyma cells, the bundle sheath, which is particularly well developed on the sides toward the centre and toward the periphery of the stem. The phloem is made up mostly of sieve tubes and companion cells, and the xylem of vessels and wood ...
This difference between dicot and monocot species in diurnal variation of the leaf elongation rate and leaf thickness may partly be explained in terms of the different position of the growth zone and possibly by a difference in elasticity of the tissue of halophytic monocotyledons and dicotyledons. ...
Copper, cadmium and nickel pollution inhibit growth and promote ascorbate catabolism in cell cultures of Arabidopsis thaliana and Zea mays We established model systems for exploring the roles of symplastic and apoplastic ascorbate in heavy-metal-polluted dicot and monocot cells.
