Problems related to seeds?
My teacher gives me some unknown seeds that are small are of different colours (yellow and brown mostly). I am given the instructions to first soak the seeds for 10 hours, then put them on cotton and water them every day.
The seeds did germinate but then there is a white covering some of the seeds. It looks like the white frosting dust of sweets. When I water the seeds, it turns transparent and the next day, the white covering is still there.
1. What seeds are they?
2. What is the white covering.

Won't know what the seeds are until they grow into plants. Carefully plant them in potting soil, and see what they look like in another month.
