PROKARYOTES AND EUKARYOTES
Organisms which have no true nucleus and no membrane-bound organelles.
What are prokaryotes?
What is the stable internal steady state that exists within an organism called?
What is homeostasis?
In which two ways are viruses similar to cells?
What is
> they have nucleic acids (DNA OR RNA)
> they change over time (evolve)
A reference to the life span of a cell.
What is the cell cycle?
The cell cycle ends with the cell splitting into two cells that have the same kind and number of chromosomes in a process called _____________.
What is mitosis?
Organisms which have a true nucleus and have complex, membrane-bound organelles.
What are eukaryotes?
The movement of any type of molecule from a region of high concentration to a region of low concentration is called __________.
What is diffusion?
The two parts which make up a virus
What is
> protein coat (capsid)
and
> nucleic acids (DNA or RNA)?
The part of the cell cycle where DNA is replicated.
What is the Synthesis phase?
The type of cells that undergo mitosis.
What is body or somatic cells?
The Staphylococcus bacteria are examples of which type of organism?
What is prokaryotes?
The movement of water across a semi-permeable membrane from a region of high concentration to a region of low concentration is called osmosis. Does the cell have to use its own energy to complete this process and what type of transport is it called?
What is no energy is required and passive transport.
The virus replication cycle that causes a cell to burst.
What is the lytic cycle?
The cell spends 75 - 80% of its time in this phase.
What is interphase?
The stages of mitosis in the correct order.
What is prophase, metaphase, anaphase, telophase?
Black bread mold and amoebas are single celled organisms which belong to the _______ group.
What is eukaryotic?
The sodium-potassium pump and the processes of endocytosis and exocytosis are types of cell transport that requires the use of cellular energy. What is this type of transport called?
What is active transport?
The human body system most affected by HIV.
What is the immune system?
What is the cell doing when it is not dividing?
What is preparing to divide?
Chromosomes line up in the middle of the cell.
What is metaphase?
The kingdom Plantae and the kingdom Animalia are both made up of ____________ cells.
What is eukaryotic?
Why is it a requirement for cells to transport materials across the cell membrane both into and out of the cell?
What is to maintain homeostasis?
Why is a virus considered to be nonliving?
What is because it can only reproduce within a host cell and doesn't show any other signs of life.
G0
When is the cell resting?
The number of chromosomes in each normal human body cell at the end of mitosis.
