What determines the number and types of organelles in a eukaryotic cell?

The right answer is the function.

If we take as an example the different cells of the human body:

Macrophages are phagocytic cells, so it has more lysosomes and peroxisomes than other cells.

Plasma cells produce a huge amount of antibodies so their nucleus, endoplasmic reticulum and Golgi apparatus are highly developed.

Muscle cells are very active cells, so they have a large number of mitochondria.

The adipocytes have the role of storing fat, and for that, they have large vacuoles ...

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
