One cell organisms are called unicellular. does that answer your question?
Sex organs is another name for reproductive organs. The testicles and ovaries, which produce the sex cells, may also be called gonads. The external sex organs -- the penis and vulva -- are sometimes called the genitalia or the genitals.
Cells ---> tissues ----> organs ----> organ systems ----> an organism.
Organelle which is the word used to describe the parts of cells with specific function as they act like mini organs.
"They all have something to do with cells." hope this helped (:
Onions do not have organs but do have cells
Epithelial cells line the inner surface of organs.
Cell tissues actually make up organs and there are different types of cells for different types of organs
Organs do not function in cells. Organs are made of various tissues types, while tissues are made of cells.
Well, organs are actually made of cells. :P Loepsie
Because stem cells are the undifferentiated cells, they are able to grow into many different kinds of 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.
Organelles which make cells which make tissues which make organs which make organ systems which make organisms
