White Blood Cell Project
By Rukmini and Amy
White blood cells protect your body against infections. They are in your blood vessels, but will travel through blood vessel wall to fight infection elswhere. There are diffrent types of white blood cells. Granulocytes (neutrophils, eosophils and basophils), monocytes and lymphocytes (T cells and B cells).
What is a White Blood Cell?
Cell Organelles
Cell Membrane- This is a thin "skin" around cytoplasm. It controls entry and exit of material into the cell. There should only be one cell membrane in each cell because that is all that is needed for the cell to function. There is one cell membrane in a white blood cell.
Cell Membrane
Cytoplasm- This is a gel like substance that fills the cell. Cell reactions occur here. White blood cells should contain cytoplasm because it supports all other organelles. White blood cells contain cytoplasm.
Cytoplasm
Mitochondrion- Sausage shaped structures that are the "powerhouse of the cell". It produces energy for the cell. There are no mitochndria in a white blood cell because it isn't needed.
Mitochondrion
Vacuole- Fluid filled sacs of various sizes.They store food, waste, and water. White blood cells have some vacuoles.
Vacuole
cylindrical-organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division
Centriole
The Golgi Apparatus are tube like structures that package proteins. It is needed in a white blood cell to to produce proteins for the cell. There are some in a white blood cell.
Golgi Apparatus
Rough Endoplasmic Reticulum is a network of thin membranes found in the cytoplasm. It is a transport system for proteins. White blood cells have rough endoplasmic reticulum to transpart proteins. There are many in a white blood cell.
Rough Endoplasmic Reticulum
Smooth Endoplasmic Reticulum is a network of thin membranes that is found in
Smooth Endoplasmic Reticulum
Nuculear membrane-The nuclear membrane is a double layer that encloses the cell’s nucleus, where the chromosomes reside. The nuclear membrane serves to separate the chromosomes from the cell’s cytoplasm and other contents.
Nuculear Membrane
Nucleus-the central and most important part of an object, movement, or group, forming the basis for its activity and growth or the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass.
Nucleus
Nucleolus- a small dense spherical structure in the nucleus of a cell during interphase.
Nucleolus
Chromatin-the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA.
Chromatin
Lysosomes-an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
Lysosomes
Cell wall-A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane. All cells have cell membranes, but generally only plants, fungi, algae, most bacteria, and archaea have cells with cell walls. The cell wall provides strength and structural support to the cell,
Cell Wall
white blood cells are made out of bone marrow and their leaves of production are regulated by organs such as the spleen,liver and kidneys granulocytes and agranulocytes are the tow types of white blood cells (leukocytes). Granulocytes contain granules or
sacs in their cytoplasm and agranulocyets do not.
How Are White Blood Cells Made?
A leter is equal to a thousand microleters
Leukopenia is where the number of white blood cells are fewer than 4000 cells per microleter of blood.
Leukocytosis is an increase in white blood cells to more than 1100 cells per microleter of blood.
White blood cells can be deformed by infections, genetic disorders, autoimmune deseases and in rare cases , cancer.
