It has to do with the ratio between their surface area and volume. As a cell gets larger in size, its volume tends to expand greater than its surface area. As nutrients and wastes can only be exchanged at the surface of a cell, its size is dictated by the ratio between its internal requirements for nutrients and wastes and the surfaces ability to exchange them with its environment. Sooner or later a cell reaches its maximum size because its nutrient/waste exchange requirements are maxed out by its surface area to do so.
What else can I help you with?
Does small animals have small cells?
No, all multicellular organisms have the same size cells.
What test can prove that bigger organisms have bigger cells?
The simplest test would involve comparing the size of cells in two different organisms of varying sizes under a microscope. This would involve calculating the average size of cells in each organism and comparing the results. If consistently larger cells are found in the larger organism, it would support the hypothesis that bigger organisms have bigger cells.
What kind of test could you do to find out if bigger organisms have bigger cells?
You can get a microscope and get a pice of your organism and see the size of the cells and compare it to the size of another organism, say a plant cell.
How do organisms grow?
Organisms grow through cell division, where existing cells replicate and increase in number. This process is controlled by genetic instructions that determine when and how cells should divide, leading to overall growth in size and development of new tissues. Additional factors such as nutrition, hormones, and environmental conditions also play a role in regulating growth.
Is the elephant cell have the same size of our cells?
Yes they are the same size, our cells and elephant cells are all animal cells, the cells within our bodies differ in size according to their function as do any other multicellular organisms, but if you took a cell from the heart of a human or from an elephant they would be close to each other in size.
Does small animals have small cells?
No, all multicellular organisms have the same size cells.
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.
What test can prove that bigger organisms have bigger cells?
The simplest test would involve comparing the size of cells in two different organisms of varying sizes under a microscope. This would involve calculating the average size of cells in each organism and comparing the results. If consistently larger cells are found in the larger organism, it would support the hypothesis that bigger organisms have bigger cells.
Does small animal have small cell?
All living things are made up of cells. Because they are small in size does not mean that their cell size is small. Generally cells are the same size between organisms.
What kind of test could you do to find out if bigger organisms have bigger cells?
You can get a microscope and get a pice of your organism and see the size of the cells and compare it to the size of another organism, say a plant cell.
Does bigger organism have more cells than smaller organism?
No. One of the largest phenomenons in genetics and biology is the C-value paradox: organisms such as flies may have significantly more DNA than animals as large as elephants. There is absolutely no correlation between the size of an animal and the amount of DNA it has in its genome. This is due to varying amounts of repeating and "nonsense" DNA present in any given species' genome. Unless you are talking about the physical size of an organism's DNA, in which case all organisms have DNA made from the same nucleotide subunits which maintain the same size throughout all of creation. What changes is the amount of nucleotides, and therefore the size of the genome.
Is the length of nerve cell different from rat and giraffe cells?
according the size of the organisms it will a different length.
Growth of many -celled organisms is due to an increase in what?
It is due to the increase in the amount of cells. The growth of single-celled organisms is due to the increase in the size of the cell.
Do bigger cells have bigger organisms?
Bigger animals are bigger because they have more cells not bigger cells. You would think that this would be so, but cells can only function up to a certain size. So, no, they are not.
Why cells don't just continue to grow larger as organisms grow larger?
Different cells are needed to do different jobs and be at different places. If cells are growing continually larger, there would not be enough cells to do all of the different jobs at the same time.
What increases in order for a many celled organisms to grow?
Many celled organisms grow by increasing the number and size of their cells through cell division and cell growth. This involves processes like mitosis, where cells replicate and divide to form new cells, and cellular growth, where cells accumulate more cytoplasm and organelles to increase in size. Additionally, the organism may also accumulate more cells through processes like cell proliferation or cell differentiation.
How can competition limit a population size?
There is a limit to available resources and all organisms in an ecosystem compete for those resources. Those that are better adapted, will obtain higher amounts of those resources leaving less for those that do not have the best abilities. These organisms that did not obtain all the resources they needed will die therefore controlling population growth and the size of the population.
