Plant Growth and Buds
Embryonic tissue is made up of actively growing cells and the term is normally used to describe the early formation of tissue in the first stages of growth. It can refer to different stages of the sporophyte and gametophyte plant; including the growth of embryos in seedlings, and to meristematic tissues, which are in a persistently embryonic state, to the growth of new buds on stems.
In both gymnosperms and angiosperms, the young plant contained in the seed, begins as a developing egg-cell formed after fertilization (sometimes without fertilization in a process called apomixis) and becomes a plant embryo. This embryonic condition also occurs in the buds that form on stems. The buds have tissue that has differentiated but not grown into complete structures. They can be in a resting state, lying dormant over winter or when conditions are dry, and then commence growth when conditions become suitable. Before they start growing into stem, leaves, or flowers, the buds are said to be in an embryonic state.

Famous quotes containing the words plant, growth and/or buds:
“Here come the line-gang pioneering by.
They throw a forest down less cut than broken.
They plant dead trees for living, and the dead
They string together with a living thread.”
—Robert Frost (1874–1963)
“Here commences what was called, twenty years ago, the best timber land in the State. This very spot was described as “covered with the greatest abundance of pine,” but now this appeared to me, comparatively, an uncommon tree there,—and yet you did not see where any more could have stood, amid the dense growth of cedar, fir, etc.”
—Henry David Thoreau (1817–1862)
“Rough winds do shake the darling buds of May.”
—William Shakespeare (1564–1616)
