Tiny organs of the cell are called?

organelles are the answer


How are organells in a cell like organs in a human body?

Organelles in a cell, such as the nucleus and mitochondria, perform specific functions similar to organs in the human body. Just as organs work together to maintain the overall health of the body, organelles collaborate to sustain the cell's functions and viability. Both organelles and organs are vital components that contribute to the overall structure and function of the cell or body.


Is organs found within a cell?

cells group togather and make tissues, tissues combined make organs


explain why hormones in the bloodstream are able only to affect target cells/organs and not other cells/organs?

Hormones in the bloodstream are able to affect target cells/organs and not other cells/organs because of selective permeability. This means that hormones are only able to pass through the cell membrane of certain cells and organs, and not through the cell membrane of other cells and organs. The cell membrane of the target cells and organs are specialized to allow the hormones to pass through, while the cell membrane of other cells and organs are not specialized and are therefore impermeable to the hormones. This is due to the presence of receptor proteins on the cell membrane of the target cells and organs. These receptor proteins can bind to the hormones and facilitate their entry into the cell. Since these receptor proteins are not present on the cell membrane of other cells and organs, the hormones are unable to bind to them and therefore unable to cross the cell membrane. In addition, hormones can be broken down by enzymes in the bloodstream, which means they can’t reach their target cells and organs if they are exposed to the enzymes. This further ensures that hormones only affect the target cells and organs, and not other cells and organs. In summary, hormones in the bloodstream are able to affect target cells and organs and not other cells and organs because of selective permeability and the presence of receptor proteins on the cell membrane of the target cells and organs. Other cells and organs do not have these specialized receptor proteins and therefore cannot be affected by the hormones.


Why is cell division and cell specialization important for creating organs in a fetus?

Cell division allows for the growth and development of the fetus, while cell specialization ensures that different cells have specific functions in forming different organs. Both processes are essential in creating organs during fetal development as they ensure the right cells are present and organized to form functional structures.
