Thanks all for your answers and thank you very much for the info & links Nik4me.
-Yes, I put the plant at a pretty much light place, but the window is close. Because when it was at water, it got one thick root without a stem. So, I decided to transfer it into the soil. Once I put it there, the stem started growing but without leaves. The place was a little bit dark so I noticed that the stem started going to the source of light, it became like a curve. So I re-placed it at a pretty much light place so that the sunlight can reach to the plant and I left it there. When I set it there, the leaves started growing pretty well until getting to that condition.
-Never thought of water not to be enough. Although, I don't think so, but when I read in the links Nik4me provided, it's stated that young avocado trees tend not to absorb water well. So, maybe. But if this were the case, it should have affected the leaves' color. The leaves are still green not brown or yellow.
-Regarding the yellow object: The yellow object is the seed; the most important thing.
When you open an avocado fruit, you will find a brown seed inside. The brown color is just a thin crust/cover/skin, you can remove it easily, when you remove it, you will find the seed like the picture. It's NOT PRETTY yellow in reality. The actual color is light, it looks like page & creamy color. It may look a light yellow after months of planting.
-About the outside brown cover: it said, this cover is playing a role on growing. It affects on a plant growing process. I read that removing it makes the growing of a plant slow while others say, removing it will make growing faster; I had removed it before reading that. I don't know which one is right but I tend to believe that this brown cover somehow is really affect growing, especially when the weather's cold, I think this will help the seed to stay warm; so it might have been better if I didn't remove it when the seed was at water.
-Side Note: Whether you start planting from water or soil, the seed always needs to be set like the picture. Half of it in the soil/water, and the other half towards air. But be careful not to set the seed on the wrong side; one part of the seed is identified for the stem and the other one for the root. Otherwise, you may end up with stem & root going to the same direction
(
it happened with me with the other seed).
-The pot has big holes at the bottom.
-I put the plant in a big pot in order not to find myself need to transfer it into a bigger pot at short period of times, so that I could avoid a 'transition shock'. Otherwise I really would like to change the pot not only for the soil but for a new pot. So, for now I'll not add water until make sure of the inside not to be wet, if the situation is constant, not develop into something else, I'll leave the plant until getting a little bit bigger and stronger so that I can consider changing the soil and pot.
Thanks again for your interest.
