Question 2 - 10
• What is the main function of the cell wall?
Answer 2 – 10
• To support and protect the cell.
Question 2 - 20
• What are the threadlike structures that
contain the genetic information of the cell
called?
Answer 2 – 20
• Chromosomes
Question 2 - 30
• List two functions of the cytoskeleton.
Answer 2 – 30
• To maintain shape
• To aid in movement
Question 2 - 40
• What are the two functions of the nucleus?
Answer 2 – 40
• Contains the cells genetic material in the form
of DNA.
• Controls cellular activity “control center” of
the cell.
Question 2 - 50
• What would be the result of a cell not having
ribosomes?
Answer 2 – 50
• No proteins.
Question 3 - 10
• Name an example of an organ.
Answer 3 – 10
Question 3 - 20
• A group of similar cells that perform a
particular function is called _________?
Answer 3 – 20
• Tissue
Question 3 - 30
• Who was the first person to identify and see a
cell?
Answer 3 – 30
• Robert Hooke
Question 3 - 40
• List the four levels of organization in order
from simplest to most complex.
Answer 3 – 40
• Cell > Tissue > Organ > Organ System
Question 3 - 50
• What does cell theory state?
Answer 3 – 50
• All living things are composed of cells.
• Cells are the basic units of structures and
function in living things.
• New cells are produced from existing cells.
Question 4 - 10
• Molecules tend to move from an area where
they are more concentrated to an area where
they are less concentrated. This process is
called _______________.
Answer 4 – 10
• Diffusion
Question 4 - 20
• A type of membrane that allows some
molecules to pass through and does not allow
others to pass through.
Answer 4 – 20
• Selectively permeable.
Question 4 - 30
• What is passive transport?
Answer 4 – 30
• Diffusion that does not require energy.
Question 4 - 40
• Explain Osmosis.
Answer 4 – 40
• Water moving from an area of high
concentration to and area of low
concentration.
Question 4 - 50
• How do facilitated diffusion and active
transport differ?
Answer 4 – 50
• FD – movement of larger molecules across the
cell membrane through protein channels.
Does not require energy.
• AT – Movement of material across the cell
membrane against a concentration difference.
This does require energy.
Question 5 - 10
• Prokaryotes lack a ______________.
Answer 5 – 10
• Nucleus.
Question 5 - 20
• The cells in a multicellular organism have
specific jobs. This is called cell ____________.
Answer 5 – 20
• Specialization
Question 5 - 30
Answer 5 – 30
• Centrioles
Question 5 - 40
• Compare a cell from a unicellular organism
with a cell from a multicellular organism.
Answer 5 – 40
• Uni - the cone cell carries out all of the life
processes of the organism.
• Multi – Cell are specialized to only carry our
specific functions. They rely on either
specialized cell in the same organism to
complete other life processes.
Question 5 - 50
• Compare the cell membrane to a mosaic.
Answer 5 – 50
• Mosaics are made up of many difference tiles
and the cell membrane is made up of many
difference molecules.
