The cell, as you most likely know is the smallest working part in the body. Cells, do get a bit bigger, but then undergo mitosis, the splitting of the cell.
Think about it like this. If a cell kept getting bigger and bigger.....could you imagine yourself with a gigantic lump of a cell inside you?
The cell splits so you have more of them, because every cell eventually dies, and so they can fit easily through your veins. A big cell would get stuck and cause many issues such as heart attack and strokes.
Cell organelles have to "communicate" with each other, so to speak, and they would not grow with the cell if it were to get bigger. This wouldn't be very practical.
Bigger cells would also need more resources, and the same quantity might not be available all the time.
For the cell to function quickly and properly, the cell needs to have a large ratio between its surface area and volume. If it does not, the cell will not be able to intake nutrients sufficiently.
If the cell is too big it will be inefficient. Basically the cell needs to stay small in order to communicate properly and to transport nutrients efficiently and with speed.

Specialized cells are dependent on other specialized cells because they need to live off other cells otherwise specialized cells wouldn't exist. Every specialized cell is designed to carry out a special function, there for we need a bunch of different specialized cells for the entire organism to survive.
why can small cells exchange substances more readily than large cells?
Cells that need more respiration typically include those that are highly active and require lots of energy. Examples of these cells include: Cells in muscle tissue Brain cells Cells in the heart Cells in the lining of the small intestineThese cells require more respiration in order to produce the energy they need to perform their intended functions.
Plant Cells need hypotonic enviroment in order to stay turgid because Plant cells wither in an isotonic solution because there must be an inflow of water into the cells for the plant cell to stay turgid against its cell wall.
They need to stay alive to support the organism
We can not give you an answer as you do not give a choice. However, cells stay small because they are the right size to function properly. Perhaps you can select an answer from that.
Too small or Llams oot
Oxygen, Energy, and Nutrients
because it can flow also blood in these blood vessels or the stay there if the cells need oxygen
Because they Are so small they can't get out.
your body
yes. cells are very small and you need to have a microscope to see them
