Why do cells get so big than divide?
Cells are dependent on the ration between surface area and volume. as the cels get bigger the ratio decreases, meaning that the volume gets larger faster than does the surface area. they cant survive past a certain point, because the nutrients that permeate the membrane have a harder time diffusing throughout a larger volume with a comparatively smaller surface area. this is why cells divide: the volume splits in half, but the surface area stays the same.
What happens to a cells surface area to volume ratio as it gets smaller?
It increases.
What happens to the surface area volume ratio of you increase the volume of a cell?
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membranefast enough to accommodate the increased cellular volume.When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.That is why cells are so small.
Why cells are mostly so small?
Actually, some are large enough to be seen without a microscope. The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.If the cell grows beyond a certain limit, not enough material will be able to cross the membranefast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
What can large cells do that will increase their total surface area to volume ratio?
By adding elongated extensions to the cell the surface area to volume ratio will be increased. One good example of a type of cell that can get very large but still have adequate oxygen diffusion rates is a neuron, some of which can have meters long axons in some animals.Flatten it. The shape should be as far from spherical, and the cross section as far from circular as possible.
Why do cells divide-?
Cells divide because the larger the cell becomes the less efficient it is. So they multiply and younger ones come into being and they are more efficient. So they keep dividing to make more.Cells divide because when your body grows, the cells dont grow with you they divide to make morecaus sometimes they just feel like it...
What is the main way that an embryo gets bigger?
The cells are known as stem cells meaning they can become any cell type. The embryo becomes bigger because certain genes in the DNA are activated allowing the cell to divide or produce certain determination factors that will make a stem cell become a neuron, muscle cell, etc.... The embryo grows in size as the stem cells divide repeatedly and then some of the stem cells become actual specific cells.
What is the relationship between a cells surfaces area and it's volume?
The relationship is usually expressed as a ratio: surface area divided by volume. Small cells have a large surface area to volume ratio, whilst large cells have a much smaller value. This is important because the cell absorbs the things it needs, and gets rid of what it doesn't need, through the surface. If the cell gets too large, not enough exchange can take place to keep the cell going, so there is a natural limit on the size to which a cell can grow.
How do cancer cells grow and divide?
Cancer cells divide excessively and invade other tissues. They do not have density dependence or anchorage dependence. Simply put, regular cells grow in an even layer while cancer cells grow tightly and on top of each other - an unnatural mass.

What happens to the relationship between the surface area and volume of the cell as it gets larger?
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small. That may be the effect but the question as worded is purely arithmetical. Surface area is proportional to the square of the linear dimensions; volume to the cube.
Why do the cells of an adult continue to divide after the adult has stopped growing?
So that the cells had to go to each part if th body and if the stop growing the cells are still going to divide because the body gets larger and the hieght stops Edited answer: To replace the dead cells and also to repair the organism from injuries
