The answer is ribosomes. Ribosomes produce proteins for the cell.
Drosophila melanogaster an excellent model for studying fundamentals of development because many of the genes involved in the development of the fruit fly are also found in humans and the precise formation of each of their 959 body cells has been mapped.
Its many of the genes involved in the development of the fruit fly are also found in humans. Drosophila melanogasteris which is also called Fruit fly is small in size and minimal requirements, many fly's can be raised and tested within a small laboratory which does not have access time, space or funding.
Genetic factors also make this fly an ideal model organism. Drosophila melanogasteris only has four pairs of chromosomes compared to 23 pairs in humans.

<span>Compound Microscope
Compound microscope is commonly used in the schools and colleges.
It comes under the category of microscopes used in biology.
It has two lenses namely the objective lens and the ocular lens.
It provides a magnification of 1500X.
Eyepiece lens is of 10X or 15X power.
It is used to observe bacterial, protozoa, various cells, etc.
</span><span>Dissecting Microscope
It is also called stereo microscope.
Its magnification power is less than the other microscope.
It gives a 3 dimensional picture.
Due to the low magnifying power they are used to observe little bigger objects than other microscopes.
They are used in the surgeries, dissection, forensic science etc.</span>
Pre-embryonic cleavages make use of the abundant cytoplasm of the conceptus as the cells rapidly divide without changing the total volume.
