Cell SPecialization

Cell SPecialization

CELL SPECIALIZATION LEARNING GOALS We are learning the difference between cell specialization and cell differentiation. We are learning the structure and function of

various specialized cells. THE PROCESS Cell theory states that all cells come from previously existing cells All cells in an organism contain the same

DNA but are not all alike. Cells develop in different ways to perform particular functions in a process called cell specialization. RED BLOOD CELLS

Contain hemoglobin that carries oxygen in blood Are smooth so that they can easily pass through the blood WHITE BLOOD CELLS

Can move like an amoeba to engulf bacteria and fight infection SKIN CELLS Fit together tightly to cover the outside of the body

Protect the cells inside and reduce water loss BONE CELLS Collect calcium from food Allow the growth and repair of bones

MUSCLE CELLS Are arranged in bundles called muscle fibres Can contract which makes the fibres shorter and causes bones to move FAT CELLS

Have a large vacuole in which to store fat molecules How cells store chemical energy NERVE CELLS

Are long, thin and have many branches Conduct electrical impulses to coordinate body activity HOMEWORK Lab

View a muscle cell, blood cell, epithelial and bone cell Make biological drawing of each Identify features of cell that aid with what it is specialized for P60 #1-6

When done, 3.1 # 1-6 LEARNING GOALS We are learning the difference between cell specialization and cell differentiation. We are learning the structure and function of

various specialized cells.
