Discuss the different types of germination seen... - SS3 Biology Development Of New Seeds Question

Germination is the process by which a seed develops into a new plant under suitable conditions. There are three main types of germination: epigeal, and hypogeal germination.

Epigeal germination: In this type, the cotyledons emerge above the soil level, and the epicotyl elongates, lifting the cotyledons and the plumule into the air.

Hypogeal germination: Here, the cotyledons remain below the soil surface, and the epicotyl doesn't elongate significantly.

Germination is influenced by various environmental factors such as water, temperature, oxygen availability, and light. Adequate water supply is essential to activate enzymes and metabolic processes. Suitable temperatures trigger biochemical reactions, and oxygen is required for cellular respiration.
