Grass seedlings (150-minute time lapse) A seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves).
A seed pot used in horticulture for sowing and taking plant cuttings and growing plugs. Germination glass (glass sprouter jar) with a plastic sieve -lid. Brassica campestris germinating seeds. Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling. It is also the process of reactivation ...
Each seed has its own ideal sprouting time. After three to five days the sprouts will have grown 5 to 8 centimetres (2 to 3 in) in length and will be suitable for consumption. If left longer they will begin to develop leaves, and are then known as baby greens. A popular baby green is a sunflower after 7–10 days.
Keep the light source no more than 2-4 inches above the plants, adjusting its height as the seedlings grow. If multiple seedlings sprout in each container, clip the weakest at the soil line using ...
Plant development. Important structures in plant development are buds, shoots, roots, leaves, and flowers; plants produce these tissues and structures throughout their life from meristems [1] located at the tips of organs, or between mature tissues. Thus, a living plant always has embryonic tissues. By contrast, an animal embryo will very early ...
The cotyledon of grasses and many other monocotyledons is a highly modified leaf composed of a scutellum and a coleoptile. The scutellum is a tissue within the seed that is specialized to absorb stored food from the adjacent endosperm. The coleoptile is a protective cap that covers the plumule (precursor to the stem and leaves of the plant).

Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo. This is a pertinent stage in the plant life cycle that is followed by dormancy and germination. [1] The zygote produced after fertilization must undergo various cellular divisions and ...
