why do cilitated cells contain large numbers of mitochondria?

Answer 1

They have a high energy requirement. The cilia (fine hair-like structures) need to move around a lot (eg cilia lining the airways, to waft particles upwards and out), and this uses a lot of energy.

Answer 2

cillia consist of mictotubule bundles with acin fibres surrounding the actin fibres form the core of micro villi which are even smaller cilla and require energy to move. However the largest energy requriement of most of these cells is the passage of molecules across there memberane, wether that be exretion requiring hight Ca2+ levels in the cell of the requirement to increace other intracellular ions such as K+, CL- ect. these ion transportations require active transport which uses ATP produced by those multiple mitochondria

Answer 3

because the 'waving' of the cilia is a energy requiring action,and because energy is created in mitochondria,they generally have more mitochondria than another cell which would appear to be less active.
