Detailed explanation-1: -Answer. Muscle cells are specialized cells. This means that they possess specific adaptations that allow them to carry out a particular function. The function of muscle cells is movement.
Detailed explanation-2: -The definition of specialized cells are cells with unique structures and functions in the body. Specialized cells work together in groups to form different tissue types, such as muscle tissue or nervous tissue. Tissues work together to form organs that perform a specific function in the body.
Detailed explanation-3: -In order for a cell to differentiate into its specialized form and function, it need only manipulate those genes (and thus those proteins) that will be expressed, and not those that will remain silent. The primary mechanism by which genes are turned “on” or “off” is through transcription factors.
Detailed explanation-4: -Answer and Explanation: A group of specialized cells is called a tissue. A tissue might be formed of different types of specialized cells. For example, in the nervous system, you can find different types of nerve cells, or neurons, and several types of glial cells.
Detailed explanation-5: -A tissue is a group of similar cells specialised to perform a specific function. The cells that make up a tissue are similar in structure, function and origin. Examples are epithelial tissue, nervous tissue, muscular tissue, etc.
