Option 1 states that the shape and size of cells are related to specific functions. This is correct. Cells have different shapes and sizes based on the functions they perform. For example, red blood cells are round and flexible to easily travel through narrow blood vessels.

Option 2 states that some cells have changing shapes. This is also correct. Some cells, like white blood cells, are able to change their shape in order to move through tissues and perform their functions effectively.

Option 3 states that each cell has its own capacity to perform. This is correct. Each type of cell in the body has its own specific function and is capable of performing that function.

Option 4 states that the same type of cells are present in all body tissues. This statement is not correct. Different types of cells are present in different body tissues, and each type of cell has a unique function. For example, muscle cells are found in muscle tissue, while nerve cells are found in nervous tissue.

Therefore, the correct answer is option 4. Alert - correct answer should be "Different types of cells are present in different body tissues."
