osteoclasts

Explanation:

Osteoclast is a cell that makes up the bone matrix, quite large compared to other cells, multinucleated, and is involved in resorption and remodeling of bone tissue. It has a lysosome-rich cytoplasm, numerous mitochondria, and a highly developed Golgi complex.

Although it was once believed that osteoclasts came from osteoprogenitor cells, they are now known to come from bone marrow derived from coalescent monocytes.

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.

hope this   and an i get brainlsiest
