Nucleus
How many different movement methods do prokaryotic cells have?
3
Prokaryotic cells reproduce sexually or asexually?
Asexually
Define Autotrophs?
Organisms that can create their own energy from processes within their cell
What is the most common example of prokaryotic cells?
Bacteria
In order for molecules to enter a prokaryotic cell they would first need to pass through this membrane
Plasma or Cytoplasmic Membrane
What is the movement structure described in this picture? How does it work?
Cilia
They act like tiny boat oars that propel the cell through the water.
What is the term specific to prokaryotic cells in terms of how they reproduce?
Binary Fission
Define Heterotrophs?
Organisms that must consume organic matter from outside the cell
This picture is of blue-green algae. Using the terms we discussed how would you describe its feeding method?
Photoautotroph
The place where DNA is bundled on a prokaryotic cell is known as what?
Nucleoid
What is the movement structure shown in the above picture?
How does it work?
Flagella
Acts like a tail to push the cell through the water
2 daughter cells that are genetically identical to the parent
Describe the two methods heterotopic prokaryotes use to feed?
Heterotopic prokaryotes rely on diffusion to move molecules into the cell through the cytoplasmic membrane.
Bacteria also excrete enzymes to dissolve molecules outside the cell to allow them to pass through the membrane via diffusion
What does the cell theory state?
Cell theory states that living things are composed of one or more cells, that the cell is the basic unit of life, and that cells arise from existing cells.
MOST prokaryotic cells have this structure which provides shape and rigidly to the cell
Cell Wall
What is the movement method called that allows a cell to stretch and contract? Or inch along
Pseudopod
What are some of the positives of binary fission?
Can happen quickly when in the right environmental conditions
Only need one cell or organism
simple process
What is a phototroph? Give an example
Photoautotrophs are cells that capture light energy, and use carbon dioxide as their carbon source. There are many photoautotrophic prokaryotes, which include cyanobacteria(Blue-green algae).
Give 3 examples of eukaryotic organisms
Human, Oak Tree, Deer
The DNA in a prokaryotic cell can be described as what in terms of its relation to a specific position in the cytoplasm
Free Floating
If a cell moves through a pseudopod movement method what organelle specific to prokaryotic cells is it lacking and why?
Cell wall
Because a cell moving through a pseudopod movement method has no definite shape
What are some of the negatives of binary fission?
All are genetically identical
Easy to wipe out a entire colony
What is a chemoautotroph? Where are they most commonly found?
Chemoautotrophs are cells that break down inorganic molecules to supply energy for the cell, and use carbon dioxide as a carbon source.
Deep ocean vents
What is the term for when certain prokaryotic cells can swap strands of DNA?
Conjugation
