What is germination ?

Question

Answer

Germination is the process by which an organism grows from a seed or similar structure. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.

Answer

Inside a seed of a plant,an embryo  is present which has two parts radicle and plumule, in some seeds a separate food ladden tissue or endosperm is present while in others the food is stored in the cotyledon part of embryo.....in favourable conditions the radicle of embryo of seed develops in the root part of the plant whereas the plumule of the embryo develops as shoot part of the plant......nd this process is called germination.....the process in which a seed develops into a new plant is called germination

Answer

Germination occurs when a spore or seed starts to grow. It is a term used in botany. When a spore or seed germinates, it produces a shoot or seedling, or (in the case of fungi) a hypha. The biology of spores is different from seeds. A spore germinates if and when conditions are right.

Answer

Germination is the BUDDING of a seed after it has been planted in soil and remained DORMANT for a certain period of time,,,. For plants and fruits that REPRODUCE through seeds and pollen, the seeds eventually grow into YOUNG plants through the process of seed GERMINATION...

Answer

Germination is the process by which a seed develops into a new plant. It is a crucial stage in the life cycle of a plant, as it marks the beginning of its growth and development. Germination involves the activation of a dormant seed and the emergence of a radicle, which eventually develops into the root system of the plant. This process is influenced by various external factors such as temperature, water availability, oxygen, and light.

Stages of Germination:
Germination can be divided into several stages, each characterized by specific changes and developments within the seed. These stages include:

1. Imbibition: When a seed absorbs water, it undergoes imbibition. Water enters the seed through tiny openings called micropyles, causing the seed to swell and become soft.

2. Activation: Activation occurs as a result of imbibition. Enzymes within the seed are activated, initiating metabolic processes necessary for germination.

3. Respiration: During respiration, the seed utilizes stored nutrients, primarily carbohydrates, to produce energy for growth and development.

4. Radicle Emergence: The radicle, or embryonic root, emerges from the seed and begins to grow downwards into the soil.

5. Root Growth: The radicle elongates and develops root hairs, which increase the surface area for water and nutrient absorption from the soil.

6. Shoot Emergence: Once the root system is established, the shoot emerges from the seed and grows upwards towards the light.

Factors Affecting Germination:
Several external factors can influence the germination process:

1. Temperature: Different plant species have specific temperature requirements for optimal germination. Some seeds require cold stratification or exposure to low temperatures before germination can occur.

2. Water: Adequate water availability is essential for imbibition and activation of enzymes within the seed. However, excessive water can lead to seed rot or fungal infections.

3. Oxygen: Oxygen is necessary for cellular respiration, which provides energy for germination. Insufficient oxygen levels can inhibit germination.

4. Light: Light requirements vary among different plant species. Some seeds require light for germination, while others need darkness.

Conclusion:
Germination is a complex process involving multiple stages and influenced by various external factors. It is a critical step in the life cycle of a plant, as it marks the transition from a dormant seed to an actively growing organism. Understanding the process of germination is essential for successful plant propagation and cultivation.
