Is my phone dangerous?

The cell phones emit radiowaves. We know from Physics that they are pretty long, and are unable to penetrate the cells, since cells only let visible light, or less, through. So since radiowaves are bigger than visible light, they can't go through cells, and thus can't cause disease.

Photosynthesis? Why is biochemistry so complicated?

Biochemistry is the core of everything. Every single concept in biology is based on biochemistry. It is complicated, I agree. It includes deep knowledge in chemistry, as well as a general understanding of biological principles. Together, it is easier.

Why is it important to study biology? Why do I need to know how cells divide?

Biology is one of the most essential disciplines. It stands closest to life, and understanding biology would lead to better understanding life. Learning how cells divide are the first step that guide into a huge and interesting world, where curiosity drives interest.
