I have some on the go at the moment, but last year was my first year so I'm no expert ;)
I notice that when the push through the soil they form a loop that eventually straightens out with the seed on the end sometimes. After that they seem to thicken out and continue growing upwards.
LOL.... not exactly David Attenborough am I!?!?

Quoteonion seeds; can someone give me some advice on what they look like at various stages of growth.
I think the first thing is the germination temperature;
Germinate at a minimum temperature of 16°C (60°F)
Once germinated; normally in about five to six days, take covers off, and allow plenty light to the seedlings.
Grow on in Greenhouse at this temperature, ventilate as much as possible (depending upon the weather) giving maximum light at all times.
As soon as they reach the crook stage,( the seed leaf will bend over like a shepherds crook, hence the name) and the second leaf appears, prick out seedlings into 70mm (3â€) pots of any proprietary soil-less potting compost.
Grow on, giving them plenty of light, but being careful not to force them with too much heat, and too much water, 8°-10°C (45°-50°F) will do.
Watering depends so much upon the weather, so always allow them to dry out between each watering.
It is advisable to spray seedlings, from the second leaf stage with a fungicide at regular intervals to deter ‘damping off’
Gradually harden off seedlings prior to planting out.
I think that covers the crucial stages of growth, for a bit more information look in here; http://tinyurl.com/yzxd7y
Thanks for that guys it is well appreciated.
