In some plants the embryo remains in the globular or spherical form even at the time of seed shedding without showing any distinction of plumule, radicle and cotyledons, e.g., Orobanche, Orchids, Utricularia. Such plants are at a disadvantage. embryo [em´bre-o] a new organism in the earliest stage of development. Here we will discuss Fertilization in plants, Definition of fertilization, Process of fertilization and Importance of fertilization in plants. embryo (noun) (botany) a minute rudimentary plant contained within a seed or an archegonium embryo, conceptus, fertilized egg (noun) an animal organism in the early stages of growth and differentiation that in higher forms merge into fetal stages but in lower forms terminate in commencement of larval life At the chalazal end (the region opposite the micropyle) is the embryo proper. Differentiation of the embryo—e.g., the development…, …egg cell, which becomes an embryo, and the other joins with two polar nuclei to form the endosperm. Thereafter, rapid cell division provides the building blocks… Botany The part of a seed which develops into a plant, consisting (in the mature embryo of a higher plant) of a plumule, a radicle, and one or two cotyledons. I    Among humans and most other mammals, the embryo is carried in the mother's womb. …longevity of seeds, the dormant embryo plant contained within the seed will lose its viability (ability to grow) if germination fails to occur within a certain time. The diploid zygote develops into the embryo. An embryo (irregularly from Greek: , plural , lit. It consists of a root part, or radicle, a prospective shoot (plumule or epicotyl), one or…, …a new sporophyte generation—the multicellular embryo of the seed. R    Embryo definition: An embryo is an unborn animal or human being in the very early stages of development. …cell divisions to form the embryo, which remains encapsulated in the gametophyte until it breaks out and becomes an independent plant. MaximumYield Terms:    F    Plant Embryonic Development: Like animals, plant embryogenesis also occurs in the result of sexual reproduction by the fertilization of the Ovule via pollination.As a result, endosperm accompanies diploid zygote, which produces seed together.The endosperm contains dense nutrients that supply the embryo growth. The embryo rapidly enlarges at the expense of the maternal tissue and initiates typical sporophytic organization, consisting at maturity of a single axis with a root apex at one end and a…. The formation of the seed is part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants.. A developing plant or animal. The ovule in plants is a structure that encloses the reproductive cells in females which contains the nucleus, the integument and the female gametophyte. Plant embryogenesis is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo. The Other male gamete fuses with the two polar nuclei to form the triploid primary endosperm nucleus. Most people chose this as the best definition of embryo: Embryonic.... See the dictionary meaning, pronunciation, and sentence examples. The pattern of development in most ferns is a distinctive one, and indeed only in the Botrychium subgenus Sceptridium and in all species of the family Marattiaceae thus far…, …contains a minute, relatively undifferentiated embryo, which occupies only a small part of the seed at maturity. A    The embryo lies between the endosperm and fruit wall with the large scutellum facing the endosperm. The zygote produced after fertilization must undergo various cellular divisions and differentiations to become a mature embryo. After that the unborn baby is usually referred to as the fetus. In higher plants a mature embryo contains a precursor tissue for the root (radicle), stem (plumule), leaves, and one or two cotyledons. D    The scutellum is thought to be a modified cotyledon, or seed leaf. Cotyledons either store food for the growing embryo (as in monocotyledons) … Definition of Germination; Process of Plant Germination; Conditions Necessary for Germination; Factors Affecting Germination; Definition of Germination. After the proper conditions for germination (e.g., light, moisture, temperature, oxygen) are met the tiny plant embryo germinates and sprouts into a mature seedling. plant embryo definition in English dictionary, plant embryo meaning, synonyms, see also 'plant',air plant',artillery plant',bedding plant'.
