Specialized & STEM Cells
Name the two kinds of STEM cells
Embryonic stem cells and adult stem cells
What are the two methods through which cells expel wastes?
Any two from osmosis, diffusion, facilitated diffusion, active transport, and endocytosis & exocytosis
What is the Musculoskeletal System?
The musculoskeletal system includes the bones, muscles, and other tissues that hold the skeleton and muscles together (ligaments, tendons, etc).
Name the three major parts of the nervous system
brain, spinal cord, and nerves
Who is our club supervisor?
Mr. Kelleymaharaj
What is the function of white blood cells?
They kill invading viruses and bacteria. They can move like an amoeba and engulf things.
Explain the difference between endocytosis and exocytosis
Exocytosis is the method through which food or other particles are brought into a cell. Exocytosis is the opposite.
What is the function of the musculoskeletal system?
The skeleton provides structure and protection to internal organs while the muscles allow for movement.
What is the function of the nervous system?
The nervous system processes internal and external stimuli and coordinates a response.
What room are we located in usually for our meetings?
403
Name the four kinds of specialized cells we discussed in our presentation.
Red blood cells, white blood cells, skeletal muscle cells/fibre, and fat cells
Explain the difference between facilitated diffusion and active transport
Facilitated diffusion - diffusion except across a semipermeable membrane, down concentration gradient, goes through protein channels (does not require energy)
Active transport - requires ATP (energy), moves against concentration gradient
What do the bones in the system produce?
Red blood cell
What is the function of the nerves?
transmit signals to and from the brain
Name all of our co-founders
Sowmya, Zaima, Sarah, & Sheena
Why do specialized cells exist, and what is a STEM cell?
- The reason why specialized cells exist is because organisms must perform several different functions to stay alive but a single type of generalized cell can't do everything.
- A stem cell is an undifferentiated cell (un-specialized cell) which can divide to form specialized cells.
Name the five ways in which a cell "eats"
diffusion, osmosis, facilitated diffusion, active transport, endocytosis & exocytosis
The muscles allow for _____ and the bones provide ______.
movement, structure
What are the functions of the nerves, brain, and spinal cord?
How many more review day(s) do we have left before we move to AP content?
1
Explain the difference between an embryonic STEM cell and an adult STEM cell.
Embryonic stem cell:
Adult stem cell:
Provide a fact about osmosis, diffusion, active transport, facilitated diffusion, & endocytosis/exocytosis
Name five parts of the musculoskeletal system.
bones, muscles, tendons, ligaments, tissue
Name four lobes in the brain.
frontal lobe, temporal lobe, parietal lobe, & occipital lobe
How many meetings have we had so far (including today's meeting)?
six
