Each cell has a (brain / nucleus /cytoplasm ) that controls what it does.5. The thin skin around the cell is called the (cell membrane / cell plastic)6. The green bits in the cell contain (chlorophyll / polycell / oxygen)7. Similar cells work together to make a (nucleus /tissue/ organ)8. Different tissues working together to do a certain thing make a (cell/tissue/organ)
