What is Seed Germination? Seed germination may be defined as the fundamental process by which different plant species grow from a single seed into a plant. This process influences both crop yield and quality. A common example of seed germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.

What is germination short answer?
germination, the sprouting of a seed, spore, or other reproductive body, usually after a period of dormancy. The absorption of water, the passage of time, chilling, warming, oxygen availability, and light exposure may all operate in initiating the process.What is seed germination class 2?
Germination Germination is defined as the beginning of growth. The term is most commonly associated with plants, describing the process of a seed sprouting into a seedling. The term germination can also be applied to spores or buds. When seeds are dry and hard they are dormant.
What is seed germination class 6?
Germination occurs in following stages: The seeds absorb water through the seed hole. … The seed coat breaks open and the root (radical) sprout and grows downwards. Then the shoot (plumule) start growing upwards, which later produces stem and leaves. When the seedling grows green leaves, it starts making its own food.
What is seed germination class 10?
Germination refers to the method by which an associated organism grows from a seed or a reproductive structure. … This method is initiated by specific enzymes that become activated once the seed is exposed to water. The roots grow downwardly, and also the shoot grows upwards towards the soil surface.

What is germination? The process by which a mature seed undergoes activation after a period of dormancy and develops the first tiny root and shoot of the plant by sprouting is called germination. Oxygen, light and optimum temperature are needed for proper germination.

Article first time published onWhat is germination and its type?
Germination is the process by which a plant grows from seed. There are two types of germination: 1. Epigeal Germination: In this type of germination, the hypocotyl elongates rapidly and arches upwards pulling the cotyledons which move above the soil.
What is germination Wikipedia?
Germination is usually the growth of a plant contained within a seed; it results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule.
What is viviparous germination explain?
In plants, vivipary (precocious or premature germination) involves the germination of seeds while still on the parent plant. It is a widespread phenomenon in plants characterized by the lack of seed dormancy.
What is the process of germination?
The Seed Germination Process Step 1: Imbibition: water fills the seed. Step 2: The water activates enzymes that begin the plant’s growth. Step 3: The seed grows a root to access water underground. Step 4: The seed grows shoots that grow towards the sun. Step 5: The shoots grow leaves and begin photmorphogenesis.
What is seed germination PDF?
SEED GERMINATION. Germination is defined as the emergence and development from the seed embryo of those essential structures which, for the kind of seed in question, indicate its ability to produce a normal plant under favourable conditions. Structure.
What is a seed for kids?
A seed contains a miniature plant, called an embryo, that can develop into a fully grown plant. The outer shell of a seed, called a seed coat, protects the embryo. Inside the seed a nutritious material provides food to the embryo. In flowering plants this material is called endosperm.

Definition of viviparous 1 : producing living young instead of eggs from within the body in the manner of nearly all mammals, many reptiles, and a few fishes.
