Red Blood Cell

Red Blood Cells-Adapted To Carry Oxygen

1)Big Surface Area For Absorbing Oxygen-Also Helps Them Pass Through Capillaries To Reach Body Cells.

2)Packed With Haemoglobin-Pigement That Absorbs Oxygen.

3)Have No Nucleus-Leaves More Space For Haemoglobin.

White Blood Cells

White Blood Cells-Adapted To Help To Fight Against Infections/Germs In The Body.

1)Flexible Cell Membrane-So They Can Move Through The Capilliary Walls To Where They Are Needed.

2)Contain Nuclei Inside Them-The Nuclei Controls Their Life Processes.

3)Their Cytoplasm Contains Enzymes-The cell membrane has a sensitive surface to enable the cell to detect foreign bodies and destroy.
