a collection of two or more tissues that work together to perform a function
animal cell and plant cell
it is a cell wall
liver
organelles are the answer
Tiny organs in a cell are called organelles (organ-like). This includes the nucleus, Golgi body, mitochondria and others.

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 canβt 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.

they are organs that are related to the cell theory
Organelles are tiny cell sized organs. The substance that runs through these tiny cell sized organs are commonly called sub-units.
Cells don't have organs.
organelles are the answer
Tiny organs in a cell are called organelles (organ-like). This includes the nucleus, Golgi body, mitochondria and others.
no but organelles are little organs inside the cell
no
cell membrane,mitochondria,photosythesis
the organization in an organism are: the cell then the cells form into tissue then tissue forms into organs and organs helps your body systems to keep you alive. the levels of the organization in an organism are cell tissue organs and systems. cell-->tissue-->organ-->system
Organs do not function in cells. Organs are made of various tissues types, while tissues are made of cells.
