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.
The process of taking up a permanent shape size and function?
This process is called "differentiation," where cells become specialized in structure and function to carry out specific roles within an organism. Differentiation involves the activation and deactivation of specific genes to produce cells with distinct shapes, sizes, and functions. It is a crucial aspect of development in multicellular organisms.
What are the differences in onion cells cheek cells and amoeba cells?
Onion cells are plant cells, cheek cells are human cells and amoebas split? (i'm smart as well as beautiful, I also managed to keep my airhead image by putting a ? at the end, *giggles flirtily*)
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.
Group of cells that has a specific job?
describe cells that have changed their shape to do a special job
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.
What is the difference between paramecium and elodea cells?
Elodea Is a multicellular celled organism, paramecium is a single organism Another thing is that Elodea (being multicellular) can not survive on its own while on the other hand paramecium can
Is a spirogyira a cell or tissue?
Spirogyra is a filamentous green algae made up of individual cells. Each cell has a distinct cylindrical shape and can be found connected in long chains to form filaments. Therefore, spirogyra is not a tissue but a multicellular organism composed of individual cells.
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).

What is the simplest level of organization in a multicellular organism?
The simplest level of organization in a multicellular organism is the cell. Cells are the building blocks of tissues and organs, each performing specific functions to contribute to the overall functioning of the organism.
What a multicellular fungus looks like depends on what?
The specific type of fungus, such as yeast, mold, or mushrooms, determines its appearance as a multicellular organism. Factors like color, shape, texture, and structure differentiate between different species of multicellular fungi. Additionally, environmental conditions can influence the growth and overall appearance of a multicellular fungus.

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.
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.
