What is mitotic apparatus?

What is stomatal apparatus? Explain the structure of stomata with a labelled diagram.

A double slit apparatus is immersed in a liquid of refractive index 1.33. It has slit separation of 1 mm and distance between he plane of slits and screen is 1.33 m. The slits are illuminated by a parallel beam of light whose wavelength in air is 6300 oversetcircA One of the slits of the apparatus is covered with a thin glass sheet of refractive index 1.53. Find the smallest thickness of the sheet to bring the adjacent minimum on the axis.

What would happen to the life of a cell if there was no Golgi apparatus ?
