If germinating seeds are kept in closed tight containers, there will be not occurs complete development of fruit. The seed contains embryo which develops into seedling under only appropriate conditions. It requires air and moisture for complete development of seed to fruit.

Introduction:
When germinating seeds are kept in a tightly closed container, several factors come into play that can affect the growth and development of the seeds. In this response, we will discuss the various consequences of keeping germinating seeds in a tightly closed container.

1. Lack of oxygen:
One of the immediate consequences of keeping germinating seeds in a tightly closed container is the lack of oxygen. Seeds require oxygen for respiration, which is crucial for the metabolic processes involved in germination. Without enough oxygen, the seeds may fail to germinate or experience stunted growth.

2. Accumulation of carbon dioxide:
As the seeds respire and release carbon dioxide, the tightly closed container prevents its escape. The accumulation of carbon dioxide can create an unfavorable environment for the seeds. High levels of carbon dioxide can inhibit the germination process, leading to poor growth and even death of the seeds.

3. Increased humidity:
A tightly closed container can trap moisture and increase humidity. While some seeds require a certain level of humidity for germination, excessive humidity can lead to the growth of fungi and mold. These pathogens can attack the seeds, causing diseases and hindering their growth.

4. Lack of light:
In a tightly closed container, seeds are likely to be deprived of light. Light is essential for the process of photomorphogenesis, which helps seedlings establish proper growth patterns and develop chlorophyll for photosynthesis. Without light, the seedlings may become weak, pale, and elongated, a condition known as etiolation.

5. Increased temperature:
A tightly closed container can trap heat and increase the temperature around the germinating seeds. Higher temperatures can accelerate metabolic processes, including respiration. However, excessive heat can also lead to heat stress and damage the delicate tissues of the seeds, inhibiting their growth and viability.

Conclusion:
In conclusion, keeping germinating seeds in a tightly closed container can have several negative consequences. The lack of oxygen, accumulation of carbon dioxide, increased humidity, lack of light, and increased temperature can all hinder the growth and development of the seeds. It is important to provide suitable conditions for germinating seeds, including proper ventilation, light exposure, and optimal temperature and humidity levels, to ensure successful germination and healthy seedling growth.
