Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is true about multicellular organism’s cells?
A
They are identical so the organism doesn’t reject them.
B
They are specialized so they do not infect other organisms in the area.
C
They are all identical so the organism is able to perform life functions.
D
They are specialized so they can carry out unique functions for the organism.
Explanation: 

Detailed explanation-1: -Multicellular organisms are made up of millions and trillions of cells. All these cells perform specific functions. All the cells specialised for performing similar functions are grouped together as tissues in the body. Hence, a particular function is carried out by a group of cells at a definite place in the body.

Detailed explanation-2: -Which of the following is true about the cells in a multicellular organism? The cells contain the same genes but do not express the same genes.

Detailed explanation-3: -Multicellular organisms carry out their life processes through division of labor. They have specialized cells that do specific jobs.

Detailed explanation-4: -Multicellular organisms need cells to carry out different functions and work together to support a balance in the system called homeostasis. Thus, different cells become specialized for various functions. The definition of specialized cells are cells with unique structures and functions in the body.

Detailed explanation-5: -The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.
