WHAT IS GERMINATION
LIST THE TWO TYPES OF GERMINATION
There are two types of germination present. A hypogeal germination is where the cotyledons remain below the surface of the soil (e.g. maize and broad bean). The other type of germination is called epigeal germination, where the cotyledons are carried above the ground (e.g. sword bean seed). Maize grain germination can be termed as hypogeal germination.
germination is the process whereby seeds or spores sprout and begin to grow

Germination is the process by which a seed develops into a new plant. It involves the activation of the seed's embryo and the growth of the root and shoot systems. Germination usually begins with the absorption of water by the seed, followed by the activation of enzymes and the initiation of metabolic processes.
There are two main types of germination:
1. Hypogeal Germination: In this type, the cotyledons (seed leaves) remain below the soil surface during germination. The epicotyl, which is the embryonic shoot, grows upward and forms the stem, while the radicle, the embryonic root, grows downward and forms the root system. The cotyledons usually remain as storage organs and do not photosynthesize. Examples of plants with hypogeal germination include peas, beans, and peanuts.
2. Epigeal Germination: In this type, the cotyledons emerge above the soil surface during germination. The epicotyl elongates and raises the cotyledons into the air, where they become green and begin to photosynthesize. The radicle also grows downward to form the root system. Examples of plants with epigeal germination include sunflowers, tomatoes, and lettuce.
To identify the type of germination a plant has, observe whether the cotyledons remain below the ground (hypogeal) or emerge above the ground (epigeal) during germination.
