Cell Form & Function. Cells have different shapes to do different jobs. A cell’s form (shape) is adapted to its function. What does this mean???? It means:
Cell Types. Blood Cells RBC – Round, double concave – No nucleus – Able to alter shape (slightly) to move through capillaries.

CELL specialization, SHAPE & FUNCTION

PLANT VS. ANIMAL CELL PLANT CELLS ANIMAL CELLS ONION CELLS HUMAN CHEEK CELLS

ELODEA CELLS Notice the chloroplasts inside the cells… What is the function of chloroplasts? Would you find these structures in cheek cells?

Cell specialization Cells specialize to carry out specific functions in an organism. Cells come in a variety of shapes… The shape of the cell is related to its function…

Human Red Blood Cells Notice the rounded shape of red blood cells What is the function of red blood cells? Carry O2 How does the rounded shape help Red blood cells do their job? Rounded shape helps blood cells move easily through blood vessels

BONE CELLS Notice the “tree-ring” pattern of bone cells What is the function of bone cells? Provide protection to soft tissue & organs How does the shape of bone cells help its function? Forms a network of strength to provide protection

NERVE CELLS What is the function of nerve cells? Communication; receiving & transmitting info through the body from organ to organ How does function relate to shape? Long thing “fibers” for transmitting information

MUSCLE CELLS What is the function of muscle cells? Movement Muscle cells are long & elastic to allow for contraction & expansion which creates movement

There are 3 types of muscle cells SKELETAL MUSCLE CARDIAC MUSCLE SMOOTH MUSCLE

SPERM CELLS What is the function of sperm cells? Fertilize the female egg How is their shape related to their function? Have long tails (flagella) to swim to egg
