Name: Ranessa Dockery I.D #: 27100017 Course: Immunohematology Lab Instructor: Sala Randall Date: January 22‚ 2013 Lab #: 1 Title: Cell Washing Aim: To demonstrate quality assurance techniques in performing cell washing. Principle: Cell washing is a common procedure performed in the laboratory. This is a series of careful steps taken to wash red blood cells normally three times intermittently with centrifugation and decanting (Harmening 2012). The procedure serves to

background knowledge relating to the current cell theory‚ the differences between prokaryotes and eukaryotes‚ and the structures and functions found within cells. Once this knowledge is known‚ a person is then able to give their opinion in the debate. In the 1800s‚ the cell theory was developed. This theory states that cells are found in all living things making them the basic units of life and that all cells come from other cells. In order to be classified as a cell‚ the object in question must be able

Compare and contrast xylem tissue and phloem tissue‚ including their respective structures and functions. The stems and roots of plants contain two separate transport systems; xylem vessels and phloem tubes‚ of which neither transport oxygen as it is transported to cells by diffusion. The network of xylem vessels transports water and mineral ions from the roots to all other parts of the plant whereas phloem tubes transport food made in the leaves to all other parts of the plant. In the stems

The cell functions much in the way a city does. Although it may be an old analogy‚ it may be one of the best. Following is a list of cell parts and how their function is similar to functions of a city or town. The cell membrane is the city limits of our city. Outside of the city limits‚ the local government has no jurisdiction‚ but inside those limits‚ people are subject to the “laws of the land”. The nucleus – This is the place where direction is given and DNA is sent from. This would

In 1838 a botanist called Schleiden derived the theory The basic unit of structure and function of all living organisms is the cell.’ Over 150 years later this can be regarded as one of the most familiar and important facts within the biological fields.

The CELL THEORY‚ or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940). Ultrastructural research and modern molecular biology have

dual-function gland‚ having features of both endocrine and exocrine glands. The part of the pancreas with endocrine function is made up of approximately a million[3] cell clusters called islets of Langerhans. Four main cell types exist in the islets. They are relatively difficult to distinguish using standard staining techniques‚ but they can be classified by their secretion: α cells secrete glucagon (increase glucose in blood)‚ β cells secrete insulin (decrease glucose in blood)‚ delta cells secrete

Cognitive Function and the Brain The brain has a major role in the area of cognition. Everything from emotion‚ problem solving‚ language‚ the way we process and categorize memories‚ and how we learn all stem from the functioning of the brain. This paper will discuss the role of the brain in cognitive functions and describe the impact that Phineas Gage’s accident had on revealing the brain’s role in cognitive function. Anatomy of the Brain Cognitive functions derive from the area of the brain

Animal Cell There are two types of cells that exist. Prokaryotic cells are simple cells that have few organelles. These cells don’t have a nucleus‚ but do have DNA. The DNA acts as a sort of “blueprint” for growth and reproduction in the cell. Prokaryotes are things like Bacteria. Eukaryotic cells are a lot more complex than a prokaryotic cell. These cells are able to convert food to energy‚ break down waste products‚ digest food‚ and assist with reproduction of new cells. Eukaryotic cells are in
