Is this true or false multicellular organism all the cells have the same shape and job?

False. Cells in multicellular organisms have a great dfference in their specilizations. Compare a neuron with a skin cell.

Give an example of changes that occur during the life cycle of a multicellular organism?
Multicellular organisms, however, typically go through a process called development. During development, a single fertilized egg cell divides again and again to produce the many cells of mature organisms. As those cells divide, they change in shape and structure to form cells such as liver cells, brain cells, and muscle cells. This process is called differentiation, because it forms cells that look different from one another and perform different functions.
Group of cells that has a specific job?
describe cells that have changed their shape to do a special job
What makes an animal cell round?
A plant cell has a cell wall which helps it keep its shape. An animal cell doesn't have a cell wall! So that circular shape represents a "blob" or something, it can take a shape because the lack of cell wall!
Why do cells in many-celled organisms different?
Cells differ because they have different functions. Nerve cells have to do nerve jobs while muscle cells have to do muscle jobs and so on. This means cells vary in shape, size etc. Some may contain more mitochondria, for example, then otehr cells. Each type of cell contains different genetic materials.
Do the cells in many-celled organism often have different sizes and shapes?
With cells, the rule of thumb is, structure defines function. Different cells throughout the body perform different functions. To perform these functions, they need different shapes. They all have the same DNA, but different "blueprints" are activated depending on where they are in the body.
Are all cell the same in a multicellular organism?
Almost all cells in a multicellular organism are genetically the same - i.e. they have identical DNA. However, through a process called "differentiation", cells diverge in size, shape, and function by having different sets of genes turned off or on.
How are cells in multi-celled organism similar and different in cell in a single cell organism?
Both!All cells in a multicellular organism are identical genetically. This is because they are all formed from a single original cell (in humans, for example, the zygote) by mitosis.However, as the organism develops, some cells will become different in shape and function; this is called differentiation, and it allows different cells to specialize for different roles. Some examples in humans: nerve cells, muscle cells, white blood cells (and there is more than one kind of each of these).

How are unicellular and multicellular alike and different?
They both have the basic unit of life, the cell. Bacteria and amoeba are examples. They are different because multicellular organisms are bigger because of the number of cells they have. They also have cells that are similar in size and shape that work together as tissues and tissues that form organs and organ systems.
What do cells have to do with living thing?
Cells are living things in and of themselves. There are single celled organism that science defines as alive as you are. You are made up of billions of cells that all have the same DNA (genetic information that is the key to making everything that you are) as each other. Humans, along with all other multicellular organisms, start as one living cell. This is the entirety of what the organism is at this point. As that cell divides and replicates itself the organism begins to take shape and eventually matures into its fully formed state. Cells continue to die and replicate in this stage. If the science behind DNA and how different genes can be turned on and off were better understood it is theoretically possible to grow an identical body from a single human cell. The first cell of any organism is the organism and is alive. If that cell were not alive or the organism itself the organism could never and would never exist.
What is the similarity between a multicellular and unicellular organism?
Unicellular organisms and multicellular organisms both contain the characteristics of life. Furthermore, both unicellular organisms and multicellular organisms follow the same genetic code and even contain the same organelles.
Why do bacteria maintain only one shape?
I'm going to give the nonscientific answer, a bacteria can only maintain one shape because it don't have enough cells to mold into another shape there for it is not multicellular (or it is I think it depends on if its arche or EU bacteria).
