Chemical weathering refers to the weathering of rocks by the use of certain chemicals

Mechanical weathering refers to the weathering of rocks by the application of physical forces or pressure or expansion of size of the rocks.

Explanation:

There are certain chemicals which helps in the decomposition of rock particles by breaking the bonds between rock particles. Feldspar is the example of chemical weathering which occurs when the substance present in the rocks combine with rain water. Due to this, rocks change into clay particles. Mechanical weathering of rocks occur due to the contraction and compression of rock due to change in temperature. Rocks also broken by applying pressure on it.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
