Answer :
Specialized cells have distinct functions, unique structures, and specific organelles that enable them to perform tasks essential for the body's maintenance.
Characteristics of a Specialized Cell
Specialized cells in the human body perform unique tasks that are crucial for overall function and maintenance. Here are the key characteristics of specialized cells:
- Particular Purpose: Every type of specialized cell has a specific purpose. For instance, nerve cells transmit electrical signals, whereas red blood cells carry oxygen.
- Unusual Structure: Nerve cells, for example, have long extensions to transmit signals over long distances. Their structure is specific to their function.
- Organelles: Muscle cells, for example, have more mitochondria to supply energy for contraction, but they also contain specific organelles that help them in their specific roles.
- Adaptability: Specific cells, like skin cells, are able to adjust to their surroundings and provide defense against infections and environmental harm.
- Tissue Formation: Organs and organ systems are constructed by tissues, which are made up of a variety of specialized cells working together.
Final answer:
Specialized cells, also known as differentiated cells, have specific structures and functions that allow them to perform specialized tasks in the body.
Explanation:
Specialized cells, also known as differentiated cells, have specific structures and functions that allow them to perform specialized tasks in the body. These cells look different from one another and have different sets of genes that are expressed. For example, muscle cells are long and contract to produce movement, while liver cells are responsible for detoxification and metabolic processes. Each specialized cell has adaptations that allow it to carry out its unique function.
