Regeneration
The zygote becomes a multicellular organism by means of cell division and differentiation.
They should be remain diploid.So they undergo mitosis.
Multicellular photosynthetic organisms are classified as plants. They are capable of producing their own food through the process of photosynthesis.
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.
Unicellular reproductions happens by MITOSISMITOSIS: IS A PROCESS WHICH ALSO HAPPENS IN MULTICELLULAR ORGANISM BUT NOT FOR REPRODUCTION, FOR MAKING NEW CELLS BY THE EXISTING CELLS WHICH DOES THE FUNCTION OF OUR GROWTH, RENEWAL OF TISSUE AND REPAIRING
The process of mitosis.
The zygote becomes a multicellular organism by means of cell division and differentiation.
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.
photosynthesis
They should be remain diploid.So they undergo mitosis.
because the in cellular differentiation, the cells can be water they need to be, the all don't have to be the same thing. So in a multicellular organism, there needs to be cells that can do multiple things so that the organism can work well. well that is what i think (I am only in 7th grade!!!) hope it helps :)
Cell Divisioncell reproduction & cell divisionCell division is the process in which it has as a role in the growth and repair of tissue in multicellular
Multicellular organisms work like an assembly line, and if one part of a multicellular organism dies, it can be replaced, but if a part of a unicellular organism dies, the entire organism dies. The assembly line process is called specialization.
Adaptation
Perception is a process by which an organism recieve certain information about environment. Perception is always based on sensation.
cell specialization
Cells multiply, doubling their population every time they do via cytokinesis. This causes growth.
