I am doing a project on Cells and I have to write a childrens book?

I am going to do an A B C book, like A- is for blah blah blah. You know what I mean? So I need a part of the cell for every letter? The Ones I already have are; cell membrane, nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, mitochondria, lysosomes, micro-tubules, micro-filaments, cilia, flagella, cell wall, and vacuoles. I need things for A B D H I J K O P Q S T U W X Y Z. I know it will be very difficult to [rovide all of these, but any help will be greatly appreciated!!!! thanks!
