Cells
What are the two main types of cells?
What is Eukaryotic and Prokaryotic cells
What is the function of the immune system?
What is to detect and destroy foreign invaders in the human body.
What is a pathogen?
What is a disease causing micro-organism
The powerhouse of the cell
What is the Mitochondria
What other subject does Ms. V teach?
PHE
woooohooo :)
What are two examples/types of Eukaryotic cells?
What are plant or animal cells
What are two examples of pathogens?
What are : Bacteria, Fungi, Protozoa, Viruses
What is an economic effect of epidemics?
- sick days ($$)
- livestock (costs farmers and communities)
Protective layer found outside the cell membrane
What is the cell wall
Why do plant cells have a larger vacuole?
What is because plants need to store water and nutrients as they can not get water whenever they want.
List threes functions of organelles.
What are :
providing protection and support
forming a barrier between the cell and the environment
building and repairing cells
transporting materials
storing and releasing energy
getting rid of waste materials
increasing in number ( multiplying)
What are four ways to transmit an infectious disease?
What is:
1. Direct contact
2. Indirect contact
3. Water and Food
4. Animal Bites
What is a vaccine and how does it work?
Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body to create antibodies. That way if the actual pathogen enters the body it has the antibodies to fight it.
Function of the centriole
What is to use their spindle fibers to aid in cell division for animal cells
What is an epidemic?
What is the occurrence of disease cases above the normal amount expected for a population in a defined area
What are the main differences between Eukaryotic cells and Prokaryotic cells?
Eukaryotic cells: have nucleus and organelles, more than one chromosome present
What occurs in the Innate response (non specific)?
1. Inflammation
2. increase in WBC (Phagocytes)
3. Phagocytes find and eat pathogens
What do antibiotics do?
What is kill, reduce growth or prevent reproduction of bacteria
What are two main differences between plant and animal cells?
Plants : Cell wall, larger vacuole, contain chloroplast, rigid structure
Animal: Multiple vacuoles, flexible structure, rounded shape
What is Ms. V's favourite animal?
Sloth
What is the Cell Theory?
What is :
1. All living things are made up of one or more cells
2. All living cells come from pre-existing cells
3. The cell is the basic building block of life
What is involved in the Acquired response?
B Cells: recognize antigens, produce antibodies, antibodies prevent/destroy antigens
T Cells: Helper T cells, recognize antigens and activate B cells
Killer T cells, destroy antigens
Activate memory B cells : reactivated if the antigen returns
(true or false) Pathogens can be killed on your skin
True
Skin has acidity from sweat which pathogens can not survive on
This organelle is the "packing and distribution" center. Collects proteins and packages into different vesicles to be shipped out/around the cell
What is the Golgi Body.
What is active transport and how is it different from osmosis and diffusion?
movement of larger molecules across a membrane using a carrier or channel protein. Osmosis and diffusion are molecules moving across the membrane from an area of high concentration to lower concentration
