       • Cell biologists:

 -Are scientists who study cells.
 ➢ Cell biologists work in labs and do experiments to study:
 -How cell work inside living organisms.
 -How cells respond to different variables.
 ➢ Cell biologists analyze data and present their researches where:

 -Some of them work with doctors G.R
   to watch how cell can work to repair cell parts or how cells respond to different medicine.

 -The other work in agriculture G.R
 To study how plant cell can work to respond to different environmental factors.

       • Staining cells:

➢ Cells are usually clear and colorless.
➢ Stains are used to add color and make the cell structure more visible.
➢ Methylene blue dye that helps you see the nucleus as a blue area.

       • Cells in 3D:

➢ Scientists have built a microscope that show the cell in 3D which means that they can
   see the top, sides and layers of cell:
  1. -The 3D microscope takes pictures of the cell in layers.
  2. -Then, a computer puts these layers together.
  3. -Finally, colors are added to the formed image.

➢ 3D Microscope can help:
   -Cell biologists learn more about cell components and how cell divide.
   -Doctors to treat cancer which is caused by cells that divide too quickly.
