The answer to this question would be: electron microscope
Cilia is a part of the paramecium membrane that looks like hairy projection. The size of cilia is too small to be examined closely using the light microscope. In this case, the electron microscope can provide a bigger magnification.
SYNAPSIS: also called syndesis
the fusion of chromosome pairs at the start of meiosis.
synapsis takes place during prophase I of meiosis.
