The Surface Area to Cell Volume ratio is very important. This is maximized with small cells. The concentration of nutrients and ions on the inside of the cell need to be able to equilibrate with the surroundings. This happens through diffusion across the membrane. The rate of diffusion increases with the surface area to volume ratio.
If a cell was several feet in diameter, it could take hours for waste products generated deep inside the cell to reach the outside. Also, transport of nutrients between organelles within the cell would take too long.
Multi-celled organisms benefit from having several smaller cells as opposed to one large one by limiting the amount of damage to the overall organism from harm to a small area. If an organism was one large cell, and this cell was poked with a needle through the plasma membrane, it would leak out its content and die. In contrast, if a multicellular human being is poked with a needle, it will be relatively unharmed, and likely very angry at whoever just poked it.

Cells are limited in size by their surface areas and what?
Cells are limited in size by their surface area-to-volume ratio. As a cell grows larger, its volume increases faster than its surface area, making it harder to efficiently exchange nutrients and waste across the cell membrane. Additionally, cells are limited in size by the efficiency of cellular processes such as DNA replication and protein synthesis.
Cells are limited in size by what?
The largest contributor to the limit on a cell's size is the ratio between its volume and its surface area. Because cells acquire nutrients through their membrane (surface), it is more favourable for a cell to have more surface. This can be accomplished by splitting the cell into 2 cells. The combination of the 2 cells has more surface area to absorb nutrients, than the surface area of a single really big cell. Thus cell's are limited in size by their need to be able to intake nutrients, which is accomplished by dividing into smaller cells.
Explain why cells can only grow to a limited size?
Cells will only grow to a certain size. If a cell gets too big, it is much harder for the cell to transport food and wastes in and out of the cell fro the nucleus. so, to avoid this, the cell divides.
What keeps cells from growing to much larger sizes than they do?
Cells are limited in size due to the surface area-to-volume ratio. As a cell grows, its volume increases faster than its surface area, leading to struggles in nutrient and waste exchange. This limitation imposes a cap on cell size to maintain proper functioning.
Are the cells of a smaller organism smaller or larger?
This is a good time for "Yes... and no." It all depends on the type of organism.In animals, which should be the both of us (If you are a human :) all cells are generally the same size. Of course, cells like nerve cells and muscle cells might not count in the reason that they can stretch to be relatively large or be the same size as other cells. For the most part, the same types of cells (i.e. bone cells, skin cells, blood vessel cells, eye cells) are the same size even in different animals. Small animals like bugs have the same size cells as larger animals like elephants or whales or birds.Bacteria though, and other single celled organisms, have cells much smaller than animal cells. In fact, more bacteria cells are present in the human body than animal cells! So, the cells of single-celled organisms are much smaller than those of multi-celled organisms. In animals, small and large have about the same size cells.

Why do all cells divide?
Cells are limited by size. They cannot grow beyond a certain extent. This is why the cells multiply to form the various organs of the body.
What are the size of cells limited by?
Cell size is limited by the cell membrane surface area to cell contents volume ratio. As a cell grows it eventually reaches a point where the cell membrane is unable to transport enough materials in and out at a sufficient rate to supply the needs of the cell. Cell size may also limited by space and other environmental factors.

Why size may be limited in cells of eukaryotic organisms base on their function?
i do not know, that's y i am asking the question!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!11
What concept explains the presence of mitochondria in cell?
The concept that explains the presence of mitochondria in cells is the endosymbiotic theory. Mitochondria in cells derived from the extra embryonic membranes.
The reason that most cells are limited to a very small size?
Most cells are limited to a small size due to the need for efficient exchange of nutrients and waste products across their cell membrane. A smaller size allows for a higher surface area to volume ratio, which facilitates this exchange process. Additionally, a small size helps maintain internal cellular functions and processes within optimal ranges.
What are cells limited to?
Anything that reduces their chance to live. Basically cells are limited to themselves.

Are cells limited in size by the rate at which substances needed by the cell can enter the cell through it's surface?
Yes. It's called the surface-to-volume ratio.
