precision seeding, where seed is placed at a precise spacing and depth; hydroseeding, where a slurry of seed, mulch and water is sprayed over prepared ground in a uniform layer. Broadcast seeding is of particular use in establishing dense plant spacing, as for cover crops and lawns. In comparison to traditional drill planting, broadcast seeding ...
Epilobium hirsutum seed head dispersing seeds. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living vectors such as birds.

Step 1: Water imbibition, the uptake of water, results in rupture of seed coat. Step 2: The imbibition of the seed coat results in emergence of the radicle (1) and the plumule (2); the cotyledons are unfolded (3). Step 3: This marks the final step in the germination of the seed, where the cotyledons are expanded, which are the true leaves.
Teaching how to draw leaves. Manual of the Mustard Seed Garden (芥子園畫傳, Jieziyuan Huazhuan), sometimes known as Jieziyuan Huapu (芥子園畫譜), is a printed manual of Chinese painting compiled during the early-Qing Dynasty. Many renowned later Chinese painters, like Qi Baishi, began their drawing
As this happens, the resulting cells will organize so that one end becomes the first root while the other end forms the tip of the shoot. In seed plants, the embryo will develop one or more "seed leaves" . By the end of embryogenesis, the young plant will have all the parts necessary to begin in its life. [citation needed]
