There are none. Organelles are found IN cells. They are made up of membranes and proteins. An organelle to a cell is like an organ to a human.
Single cell
No. Cells are not MADE UP of organelles, but they actually contain organelles. The organelle is part of the cell. The cytoplasm, water, waste, cell membrane, and cell wall are all part of a cell. You cannot call every item in the cell an organelle. Remember, it is one living thing.
The cell membrane. The shell is just an extra organelle solely made of calcium carbonate that provides structure. It is not part of the living egg, just a layer of protection. Note that the egg is only one cell
There is one main organelle that is involved in phagocytosis. The organelle involved is the cell membrane due to transportation.
Each one has a different function in the cell.
Chloroplasts, for one. This is a plant organelle used in photosynthesis.
Could be the membrane or cell wall
One cell These are all single cell organisms.
Organisms that are composed of more than one cell are known as multicellular organisms. These organisms can have specialized cells that work together to form different tissues and organs, allowing for more complex functions and structures. Examples include animals, plants, and fungi.
Organelle
No, humans are not made from a single cell. Humans start as a single fertilized egg cell that undergoes multiple cell divisions to form a complex organism with trillions of cells organized into different tissues and organs.
It does not stand for anything. It just simply means a part of a cell. i.e.: A Nucleus is one organelle in a cell.
