- Imbibition: water fills the seed.
- The water activates enzymes that begin the plant’s growth.
- The seed grows a root to access water underground.
- The seed grows shoots that grow towards the sun.

What makes a seed germinate?

One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don’t soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.
What are 3 factors that affect seed germination?
Environmental factors such as temperature, light, pH, and soil moisture are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer- gence.
Why won’t my seeds germinate?
Other conditions such as improper soil temperature and moisture, or a combination of the two, are the majority of the reasons that seeds don’t germinate in a timely manner. Planting too early, too deep, watering too much or too little are common mistakes made. Wet a paper towel and wring most of the moisture out of it.
What is needed for germination?
