Levels of Organization
All living things are made up of one or more ________.
Cells
What do we call the unspecialized cells that turn into different cell types?
Stem Cells
List the four different types of tissues found in humans
1. Nervous tissue 2. Connective tissue 3. Epithelial tissue 4. Muscle tissue
IS a blood a tissue? If so what kind of tissue is it?
Yes, Connective Tissue.
Similar cells grouped together make a __________.
Tissue.
The process where stem cells turn into specialized cell types is called ___________ ______________________.
Cell Differentiation
What is the function of nervous tissue?
To carry signals to and from the brain and throughout the body.
What is DNA? Why is it important to Cell differentiation?
Genetic code (instruction manual for the cell.) Important because it contains the information the cell needs to be able to differentiate.
What makes up an organ system?
Organs
Describe how a cell differentiates.
a cell expresses certain genes to produce proteins characteristic for that type of cell
Adipose is this type of tissue
Connective
During class we used an analogy comparing a factory making a car part to cell differentiation. In the analogy, what are the chapters in the instruction manual comparative to?
the expression of certain genes.
List 6 levels of organization starting with the organelle
organelle ,cell, tissue, organ, organ system, organism
How many types of stem cells are there and what are they?
Two- embryonic and adult stem cells
This tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types
Muscular Tissue
What is the benefit of similar cells being grouped together as a tissue?
The cells can work together to complete a function they could not carry out on their own.
List the 9 levels of organization starting with organelle
organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem
What is a therapeutic use of stem cells?
To repair and replace damaged or diseased organs and tissues
This type of tissue has the following functions:
1) It protects us from the outside world 2) Absorbs 3) Filters 4) Secretes
Epithelial Tissue
How do bone marrow transplants relate to importance of cell differentiation.
People who do not produce healthy blood cells need stem cells transplanted from the bone marrow to produce red blood cells (carry oxygen), white blood cells (fight infections), and platelets (to clot blood).
