Answer: The correct answer is A. The different types of cells found in an organism are specialized to perform specific functions.
Step-by-step explanation:
Each type of cell has a unique structure and function that allows it to carry out specific tasks necessary for the overall functioning of the organism. For example, epithelial cells form the protective covering of the body, muscle cells enable movement, and blood cells transport oxygen and nutrients throughout the body.
These specialized cells are formed through a process called cell differentiation, where cells become specialized in structure and function. During development, certain genes are activated or suppressed in each cell, leading to the development of specific characteristics and functions.
It's important to note that while every cell in an organism contains the same DNA, the expression of genes can vary between different cell types. This allows for the diverse range of cell types and functions in an organism. So, even though the DNA is the same, the way it is expressed and utilized differs among different cell types.
In summary, the reason why an organism contains different types of cells is that each cell is specialized to perform specific functions necessary for the organism's survival and overall functioning.
