Why cells do not have exactly the same structure?

Why cells do not have exactly the same structure?

In order for cells to become whole organisms, they must divide and differentiate. Cells divide all the time. That means that just one cell, a fertilized egg, is able to become the trillions of cells that make up your body, just by dividing. Those trillions of cells are not all the same though.

Why the cells in our body have different structures?

Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue. Groups of different types of cells make up the organs in your body, such as your heart, liver, or lungs.

Does all cells have the same structure inside?

That’s because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell’s internal and external environments. The cell membrane is sometimes also referred to as the plasma membrane.

Why all cells are not the same?

All cells are not the same because some are prokaryotic and some are eukaryotic. Prokaryotic cells are a very simple type, making up unicellular…

Do cells of an organ have similar structure?

The tissue is a group of cells that have the similar structure, function and from common origin. Different tissues have a different type of cells because an organ is made of different types of tissues and hence consists of different type of cells.

What if cells were all the same what would happen?

If all the cells of our body were of the same size, shape and volume, then they would all perform the same function and the multitude of other important functions cannot be carried out, without which human life itself would not be possible.

Why are cells almost always microscopic?

The scale, or size of a cell compared to other objects, is incredibly small. Cells are microscopic mostly because of this constraint. If the surface area to volume ratio is small, the cell is very big. If the ratio is big, the surface area is greater than the volume, and the cell is small.

Do all these cells have similar structure if yes why do they look different?

No,all the cells doesn’t look alike in structure because all the cells are of different shapes and perform different functions . So,we can say that different shapes are needed to perform different functions to the body.

Do all cells have the same structure and same function explain your answer?

Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell. Within cells, the cytoplasm is made up of a jelly-like fluid (called the cytosol) and other structures that surround the nucleus.

Why do all cells have the same DNA but different functions?

Gene regulation is how a cell controls which genes, out of the many genes in its genome, are “turned on” (expressed). Thanks to gene regulation, each cell type in your body has a different set of active genes—despite the fact that almost all the cells of your body contain the exact same DNA.

Why are all types of cells not the same?

Verified answer. The simple answer is that all cells are not same due to the vast difference in their internal structures. For example two type of cells are: 1) Prokaryotic: these cells have no nucleous and they are small and simple. 2) Eukaryotic: These cells have a neucleous and are large and complex as opposed to prokaryotic.

Why do some cells have walls but not all?

Some cells also have cell walls. While these cell walls provide additional protection and support, they do not replace the function of the cell membrane. A cell membrane works to keep the inside of the cell and the outside of the cell separate. You can think of it as the skin of the cell.

Why are all prokaryotic cells not the same?

The simple answer is that all cells are not same due to the vast difference in their internal structures. 1) Prokaryotic: these cells have no nucleous and they are small and simple. 2) Eukaryotic: These cells have a neucleous and are large and complex as opposed to prokaryotic.

What are the internal structures of eukaryotic cells?

Each eukaryotic cell has a plasma membrane, cytoplasm, a nucleus, ribosomes, mitochondria, peroxisomes, and in some, vacuoles; however, there are some striking differences between animal and plant cells.
