Transcript of White Blood Cells

The white blood cell is an animal cell
This cell is found throughout the body, including blood and the lymphatic system
The size of the cell is between 4 and 11x10 to the 9 power, or about 1% of the blood in your body
Organelles
Some of the organelles in white blood cells are
Lysosomes: help defend the cell and kill viruses and bacteria
Nucleus: contains genetic material
Cell membrane: encloses and helps defend cell, key in killing bacteria and viruses through absorption
Mitochondria: supply cell energy
Cytoplasm: fluid where the organelles live and work
Vacuole: used to store things in the cell, like nutrients
Macromolecules in White Blood Cells
This cell includes the four macromolecules: protein, lipids, carbohydrates, and nucleic acids. Proteins provide structural support, and help the cell produce antibodies. Carbohydrates contain short term energy and structural support. Lipids help make up the membrane and provide long term stored energy. Nucleic acids store genetic information in the nucleus.
About this Cell
Diffusion
Diffusion in white blood cells is like all other animal cells. Molecules move at random from a place of high concentration to a place of low concentration, expanding to a farther area.
Osmosis
White blood cells have a unique type of osmosis, as the cell membrane expands and engulfs the enemy cell. It then uses a chemical to destroy the cell. These are processes called endocytosis and phagocytosis. Osmosis in this cell is similar to all other animal cells, as water moves across the membrane to an area of greater solute concentration.

White Blood Cells
Mitosis
White blood cells go through a common form
of mitosis. There are several phases, which include interphase, prophase, metaphase,anaphase, telophase. During interphase, the cell grows and performs its original purpose. Prophase is when the DNA synthesizes and becomes coiled and shorter. The chromosomes then line up and centrioles attach to the chromosomes during metaphase. Anaphase is when the chromosomes are pulled to the ends of the cell by the centrioles. Finally, the phase of telophase is when the chromosomes are at both ends of the cell, and a new membrane forms through the middle to make two new cells.

Function of the Cell
The white blood cell is a vital part of the organism as a whole. It helps defend the body against bacteria and viruses by absorbing and destroying them. Without these cells, the body would be vulnerable to illnesses and harm. While it only makes up a fraction of the blood in your body, these cells are an important building block of life in protecting the body against harmful attacks.
