Cell Specialization • Specialized cells have physical and chemical differences that allow each type to perform ______ very well. Example: • Specialized cells in the lungs – help keep dirt out – orange goblet cells secrete mucus – the hair-like extensions of the cells (called cilia) move the mucus along the trachea to remove inhaled dust and dirt

Specialized Cells • Plant cells also have a variety of specialized cells. Cells in the leaf of a tree have a different structure and function from the cells in the trunk. Epidermal cells on young roots have hairs that absorb water from the soil Some plant cells transport water and dissolved minerals throughout the plant. Photosynthetic cells contain many chloroplasts to collect energy from sunlight to make sugar for the plant. Other cells transport dissolved sugars around the plant.
