A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter (135 grams per liter) of blood for men and less than 12 grams per deciliter (120 grams per liter) for women. In children, the definition varies with age and sex. The threshold differs slightly from one medical practice to another.
seed noun (PLANT) B2 [ C or U ] a small, round, or oval object produced by a plant and from which, when it is planted, a new plant can grow: Sow the seeds (= put them in the ground) about three centimetres deep. The chemical will stop all seeds from sprouting (= starting to grow).
A seed is an embryonic plant enclosed in a protective outer covering known as the seed coat. It is a characteristic of spermatophytes (gymnosperm and angiosperm plants) and the product of the ripened ovule which occurs after fertilization and some growth within the mother plant.ome plants do not produce seeds that have functional complete embryos, or the seed may have no embryo at all, often called empty seeds. Predators and pathogens can damage or kill the seed while it is still in the fruit or after it is dispersed.
