Bakelite is optically isotropic.
Aluminium and steel are e.g. of isotropic materials.
The meaning of isotropic is with identical properties independent on the direction.
An anisotropic material is a material which does not behave the same way in all directions. Take wood for example. Wood is very strong along the grain. Against the grain, however, it will easily break. The opposite of an anisotropic material is an isotropic material. Most metals (steel, aluminum) are isotropic materials. They respond the same way in all directions.
Concrete is an isotropic material with different strength properties with respect to the type of imposed loadings.
An omnidirectional antenna can be practically implemented but an isotropic antenna cannot be implemented practically. An isotropic antenna resembles an ideal antenna with ideal values for all parameters.

yes
anisotropic are the bright bands in the muscle tissue while isotropic are the dark bands when view under polarised light.
An isotropic material has properties which are independent of the direction in which they are measured whereas in an anisotropic material the properties do depend on the direction .
These substances are called isotropic.
