Seeds contain a living embryo and food to help the young plant grow. They are carried by animals and birds or dispersed by water, wind or gravity. They must reach a suitable place at a time favorable for germination and growth.
In computers, a seed is a value that helps to generate a random number or other value. It is used as a starting point for a program or algorithm.
What is a seed?
Seeds contain an embryo that will develop into a new plant under the right conditions. They also contain food stored in a special tissue called endosperm. This nutrient helps the embryo develop and grow. Endosperm contains starch and oil.
Seeds come in all shapes and sizes. They may be fleshy or dry. Some have appendages that help them disperse. Coco de mer seeds float, allowing them to travel between islands in the Seychelles. Other seeds have hooks, barbs, or sticky hairs to attach to fur or feathers of animal dispersers. Others have wings to allow them to flutter away in the wind.
Seeds are the propagating organ of plants such as trees, grasses, and grains. They are used to grow food crops such as wheat, rice, and corn. Seeds are also the source of nonfood fibers such as cotton fiber and oil from linseed, milkweed, and crambe. Seeds are also used for wood products such as linseed wood, cottonwood lumber, and rosary peas.
How do seeds grow?
Seeds serve several important functions for their parent plants, including nourishment of the embryo and dispersal to a new location. They contain the embryo of a future plant, stored food for it (called endosperm), and a protective coating called a testa.
When a seed reaches the right place it begins to grow. First, it must absorb water. Water hydrates enzymes inside the seed, and it triggers chemical reactions that break apart the hard seed coat and allow the embryo to begin growing.
Most seeds have a small root, a stem and leaf-like parts called cotyledons. They also have a supply of food to last until the embryo can grow its own leaves to make its own food. Some seeds have a physiological dormancy that prevents them from sprouting, even when conditions are favorable. This can be broken by scarifying the seed, which includes methods like soaking, poking holes in the hard seed coat or using chemicals to soften it.
What is the best lawn seed?
Grass seed can be expensive, so it’s important to find the best lawn mix for your climate and yard conditions. The Spruce’s Michelle Ullman, a home improvement/tool expert, reviewed dozens of grass seed products for germination rates, maintenance requirements, and costs. She also considered feedback from customers and experts.
For a lush green lawn in cool-season climates, this mix of bluegrass, fine fescue, and perennial ryegrass is a good choice. It can withstand summer heat and winter cold and self-repairs well after foot traffic. It’s easy to sow, but it’s essential to prepare the soil by removing dead grass and debris, spreading evenly, and watering regularly (not soggy) until the lawn is established.
For shaded lawns that get only a few hours of sunlight, this blend of fine and tall fescues is ideal. It’s slow to grow, but once it does, it fills in bare patches well and creates a dark green color. It’s also a good option for overseeding existing lawns in the fall or spring.
