INTRODUCTION
In this topic, we are going to show you how to build a Seed germination school model for your science project or exhibitions.
Seed Germination Explanation
Seed germination is a process where an organism grows from a seed. The best example of germination is sprouting of a seedling from a seed of angiosperm or gymnosperm.
Growth of sporeling from spore such as hyphae from fungal spores is also called as germination.
In general, germination can be defined as anything expanding into greater being from germ or small existence.
Germination is the growth of the plant that is contained within a seed which intern result in the formation of the seedling.
The emergence of radicle and plumule is due to the process of reactivation of metabolic machinery of the seed.
Vascular plant seed is a small package produced in fruit after the union of male and female reproductive cells.
Fully grown seeds contain an embryo and in most plant species some store the food reserve wrapped in the seed coat.
Dormant seeds lack embryo’s which never germinate.
Dormant seeds do not germinate because they are subjected to external environment conditions which prevent initiation of metabolic processes and cell growth.
Only under specific proper conditions seeds germinate and embryonic tissues resume their growth which results in developing towards a seedling.
How to make An Seed Germination Model Step by Step Video

Prepare for Science Fair Questions & Answers – Seed Germination Model
- What are the stages of germination?
Stages of germination are Effect of Light on Seed Germination, Respiration, Imbibition, Role of Growth Regulators, Mobilization of Reserves and finally development of axis of the embryo into a seedling. - How can you speed up germination?
We need to presoak seeds for 24 hours in a container filled with hot water. Water will help embryo inside the seed to pump up. - What affects seed germination?
Environmental factors like light, pH, soil moisture, burial depth, and temperature. - What seeds germinate the fastest?
Radishes, Melons, Pumpkins, Beans, Peas germinate the fastest. - What flower seeds germinate the fastest?
Marigold, Sunflower, nasturtium and annual phlox seeds germinate the fasters.
Conclusions
Germination is a process in which a seed develops into a new plant. Water helps enzymes in the process of seed growth.
