Examples of specialized cells:
Leaf cell -
Absorbs light energy for photosynthesis
Packed with chloroplasts. Regular shaped/ closely packed cells form a continuous layer for efficient absorption of sunlight.
Red blood cell -
Contain haemoglobin to carry oxygen to the cells
Thin outer membrane to let oxygen diffuse through easily. Shape increases the surface area to allow more oxygen to be absorbed efficiently. No nucleus, so the whole cell is full of haemoglobin.
