Does the bone cell contain chloroplast?

No. Chloroplast is an organelle found in a plant cell. It captured light and that's also where photosynthesis occurs.As far as bone cells go, there are a few types of those.

There's the esteoblast (create and form new bone), osteoclasts (unlike osteoblasts they destroy bones), and osteocytes (create a network in the canaliculi (canals) which are used in the exchange of nutrients an waste) I hope this helped you a little.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
