what is the defining difference between monocot and dicot seeds?
76813
Monocots have only one seed leaf inside the seed coat. It is often only a thin leaf, because the endosperm to feed the new plant is not inside the seed leaf. Dicots have two seed leaves inside the seed coat. They are usually rounded and fat, because they contain the endosperm to feed the embryo plant.

Because they form within the seeds, cotyledons are known also as seed leaves. Flowering plants, called angiosperms, have embryos within their seeds that form one or two cotyledons, also often referred to as "seed leaves". Those with one cotyledon are known as monocotyledons or monocots.

Most dicots, however, share a common pollen structure that differs from that of monocots and a minority of dicots; this large subgroup of dicots is called eudicots. A plant's pollen structure is what makes it a eudicot, but its seeds differ from those of monocots in the same way that the seeds of all dicots differ.

Gram seeds are dicot. Maize is another term for corn. Maize seeds are monocots. The most obvious difference between the gram and maize seeds is the number of embryo leaves, called cotyledons.

Monocots have one cotyledon, dicots have two. A good example of a dicot is a bean plant. A bean seed can be split in half lengthwise into the two cotyledons. Inside is the embryonic stem, root, and tiny leaves.

Physical characteristics Monocot plants are marked by seeds with a single cotyledon, parallel-veined leaves, scattered vascular bundles in the stem, the absence of a typical cambium, and an adventitious root system.

Hydrangea are angiosperms, which are flowering plants. Di" means "two," and dicot means the plants, including hydrangeas, begin life with two leaves or cotyledons.

Monocots differ from dicots in four distinct structural features: leaves, stems, roots and flowers. But, the differences start from the very beginning of the plant's life cycle: the seed. Within the seed lies the plant's embryo. Whereas monocots have one cotyledon (vein), dicots have two.

Monocots have at least three of the following: Flower parts are in 3's or multiples of 3, leaves are parallel-veined, vascular bundles appear to be scattered through the stem cross-section (= atactostele), and seeds possess one cotyledon.

Dicot stems have a circular arrangement of vascular tissues, whereas the stems of monocots have vascular-tissue bundles scattered throughout. In monocots the vascular bundles also tend to be toward the outside of the stem. ... Therefore, flowering plants with thickening, woody stems are dicots.

Monocots can be defined as the plants with the seed having only one cotyledon, and the plant is called as monocotyledons, while plants with the seed having two cotyledons are called as dicots, and the plant is called as dicotyledons.

The major difference between monocot and dicot stem is in the vascular bundle: In monocots stem, the vascular bundles are scattered across the stem without any definite arrangement. On the other hand, in dicots stem, the vascular bundles have a definite shape arranged in the form of one or two broken rings.

The main characteristic feature that differentiates a monocot and a dicot leaf is that, the guard cells of stomata are kidney-shaped in dicot leaf and dumb-bell shaped in a monocot leaf. The vascular bundle is large in dicot leaf whereas in monocot leaf, both small and large vascular bundles are present.

Flowering plants are divided into two main categories – Monocots and Dicots. Lilies are Monocots, characterized by parallel leaf veins, flower parts (petals, sepals, pistils etc.) in groups of 3's, fibrous root systems, and a single seed leaf emerging after germination.

Number of flower parts -- If you count the number of petals, stamens, or other floral parts, you will find that monocot flowers tend to have a number of parts that is divisible by three, usually three or six. Dicot flowers on the other hand, tend to have parts in multiples of four or five (four, five, ten, etc.).

Corn is a monocot, and soybeans are dicots, meaning that corn only has one cotyledon and soybeans have two. Cotyledons become the first true leaves of the plant.

The main difference between spores and seeds as dispersal units is that spores are unicellular, the first cell of a gametophyte, while seeds contain within them a developing embryo (the multicellular sporophyte of the next generation), produced by the fusion of the male gamete of the pollen tube with the female gamete ...
