Levels of Organization
All living things are made up of one or more ________.
Cell
Groups of similar cells that work together carry out specific tasks.
The root word "uni" refers to _____________
The root word "multi" refers to ____________
one
many or multiple
Do we have one type of cell that makes up the human body? If not, why?
Organisms have different cell types to perform different jobs.
Similar cells grouped together make a __________.
tissue.
What is the function of nervous tissue?
To carry signals to and from the brain
The process where stem cells turn into specialized cell types is called ___________ ______________________.
cell differentiation
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.
What makes up an organ system?
organs
Which is not a tissue type found in plants:
A. Dermal tissue
B. Vascular tissue
C. Ground tissue
E. Epithelial tissue
Epithelial tissue
What do we call the unspecialized cells that turn into different cell types?
Stem cells
How does the rocket ship analogy relate to cells, tissues, and organs work together in the human organism?
Multicellular organisms are made up of many parts that must all work together for an organism to survive. If any part or any level of this organization were defective or did not function as it needed to, survival might not be possible. Groups of cells, tissues, and organs come together and work together to complete a task required for survival. For example, the cells in the muscle tissue of the stomach cannot survive without oxygen, and the stomach cannot get oxygen without the respiratory and circulatory systems. This relates to how all the parts of a rocketship are required for the rocketship to function in space.
List the 5 levels of organization starting with cell
cell, tissue, organ, organ system, organism
List the four different types of tissues found in humans
1. Nervous tissue
2. Connective tissue
3. Epithelial tissue
4. Muscle tissue
Stem cells that can differentiate into any cell type are called: _____________.
embryonic stem cells
Dermal tissue in plants provides protection and helps reduce water loss. Which human tissue type (nervous, connective, epithelial, or muscle) relates most to plant dermal tissue and how?
Dermal tissue in plants is similar to epithelial tissue in humans because they both provide protection.
List the 9 levels of organization starting with atom
atom, molecule, organelle, cell, tissue, organ, organ system, organism, population
Explain how each tissue type (nervous, epithelial, connective, and muscle tissue) function together to form the stomach organ.
- Layers of muscle tissue contract to break down and digest food
- Epithelial tissue lines the stomach to form a protective layer
- Nervous tissue sends signals to tell you when your stomach is full
- Connective tissue gives support and structure to the stomach wall
stem cells that can only differentiate into a few different cells types (usually based on location) are called ___________________.
adult stem cells
How do bone marrow transplants relate to important 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).
