Cell Structure
The 'powerhouse' of the cell that produces usable energy through cellular respiration
What is Mitochondria?
Disease-causing microbes such as certain bacteria or viruses
What are pathogens?
The movement of particles from an area of higher concentration to lower concentration
What is diffusion?
Tiny, non-living particles that can only reproduce inside a host cell
What are viruses?
The body's primary physical barrier against pathogens, which includes sweat and oils
What is the skin?
The jelly-like fluid inside a cell where organelles float
What is Cytoplasm?
A local immune response that causes redness, heat, swelling, and pain to trap or fight off infection
What is inflammation?
The diffusion of water across a selectively permeable membrane
What is osmosis?
What are the three main ideas of cell theory
What is cells are the basic unit of life, all cells come from pre-existing cells, and cells are in all living things?
Sticky fluids found in the nose and throat that trap pathogens before they enter the body
Two organnelles found in plant cells that are usually absent in animal cells
What are the cell wall and chloroplasts?
Medications used to treat bacterial infections, which are completely ineffective against viruses
What are antibiotics?
The chemical reaction where plants use sunlight to convert carbon dioxide and water into glucose and oxygen
What is photosynthesis?
An organism made up of more than one cell
What is multicellular?
Tiny, hair-like projections in your respiratory tract that sweep mucus and trapped pathogens up and out of your airways
What is cilia?
The organelle that sorts, packages, and ships proteins.
What is the golgi apparatus?
A biological preparation that provides active immunity to a particular disease
What is a vaccine?
Unicellular or multicellular entities smaller than 1mm that require a microscope to see
What are microorganisms or microbes?
A viral or bacterial disease outbreak spreading across an entire country or the whole world
What is a pandemic?
White blood cells that engulf, swallow, and destroy pathogens in a non-specific immune response
What are phagocytes?
These small structures are responsible for protein synthesis and can be found floating freely or attached to the endoplasmic reticulum
What are ribosomes?
This type of pathogen is unicellular, has no nucleus (prokaryotic), and can be treated with antibiotics.
What is bacteria?
This term describes a membrane that allows only certain substances, like water or nutrients, to pass through while blocking others
What is semi-permeable or selectively permeable?
Viruses have genetic material but they are considered non-living because they don't have a biological unit of structure and function
What is a cell?
This system moves fluid through a network of vessels to filter out pathogens
What is the lymphatic system?
