Cellular biology
These are the structures that serve as the basic unit of life, and can be either prokaryotic or eukaryotic.
Cells
This molecule carries genetic information and is found in the nucleus of eukaryotic cells.
DNA
These organisms consist of a single cell and are capable of performing all the necessary life functions
Unicellular organisms
These are the simplest forms of life and can be found in two main groups: Archaebacteria and Eubacteria.
Bacteria
This type of pathogen causes diseases such as strep throat and pneumonia.
Bacteria
This organelle is responsible for producing energy through cellular respiration.
Mitochondria
This theory suggests that life may have originated from microorganisms or organic compounds in outer space.
Panspermia
These organisms are made up of multiple cells and are often more complex in structure.
Multicellular organisms
This term refers to a protective outer layer found on some viruses.
Envelope
This disease is caused by the HIV virus and affects the immune system.
AIDS
This part of the cell is responsible for controlling what enters and exits, and is found in both plant and animal cells.
Cell membrane
These are the small structures within cells that synthesize proteins.
These organisms make their own food through photosynthesis, such as plants.
Autotrophs
This disease is known to be a severe infectious disease and affects the skin and nerves, and is caused by a bacteria.
Leprosy
This term refers to microscopic organisms, such as bacteria, that live within an organism and can have beneficial or harmful effects.
Microbiota
This process involves the division of the cytoplasm and organelles, typically occurring in prokaryotic cells.
Binary fission
This process is the fusion of male and female gametes to create a zygote
Fertilization
These organisms depend on other organisms for food, such as animals.
Heterotrophs
This form of bacteria reproduction results in the formation of spores to withstand extreme conditions.
Sporulation
This can be prevented by vaccination.
Disease
This term refers to the process by which cells take in and convert energy from nutrients to support life.
Metabolism
This type of evolution refers to the gradual development of life from simple molecules to more complex organisms.
Chemical evolution
This term refers to organisms that survive in extreme environments, such as high heat or high salinity.
Extremophiles
This type of bacteria can be found in the digestive systems of animals, helping with the breakdown of food.
Saprophytes
This is a condition in which the body’s immune system mistakenly attacks its own healthy cells, often leading to chronic diseases.
