1. Dicots
One of the two main types of flowering plants ; characterized by having two cotyledons , floral organs arranged in cycles of four or five, and leaves with reticulate veins; include trees (except conifers) and most ornamental and crop plants.

2. Embryo
* A stage of development in a multicelled organism between the time that the zygote is fertilized and the point at which the organism developing from that zygote becomes free-living. * Specifically, in vertebrate animals, the developmental stage from after the long axis appears until all major anatomical structures form. * In human development, this is from about two weeks after fertilization until the seventh or eighth week of pregnancy. * In higher plants, this is the rudimentary plant encased in a viable seed before germination; a plant embryo usually consists of an epicotyl, hypocotyl, radicle and one or two cotyledons. * In primitive plants, the young sporophyte that develops from the union of male and female sex cells.

3. Epicotyl
The part of the stem of an embryo nic plant which is above the cotyledon s but below the first true leaves (which are attached to the apex of the epicotyl). The epicotyl develops into the shoot of the plant upon germination of the seed. (The rest of the embryonic stem, which is below the cotyledons, is called the hypocotyl ).
