cellular respiration

metabolic process cells use to convert chemical energy from nutrients, primarily glucose, into adenosine triphosphate (ATP), which serves as the cell's main energy currency. I

eukaryotic

Eukaryotic cells have a true, membrane-bound nucleus and other membrane-bound organelles like mitochondria, making them larger and more complex, found in organisms like animals, plants, fungi, and protists.

prokaryotic

prokaryotic cells lack a nucleus and other membrane-bound organelles; their genetic material is in the cytoplasm, and they are typically smaller, simpler, and include unicellular organisms like bacteria and archaea.  

immune system

The immune system is the body's defense network against infections, germs, and abnormal cells like cancer

pathogen

A pathogen is a specific disease-causing agent, such as a virus, bacterium,

photosynthesis 

Photosynthesis is the process used by plants, algae, and some bacteria to convert light energy into chemical energy in the form of sugars, using carbon dioxide and water as reactants.

vaccine

A vaccine is a medical preparation, containing weakened or killed germs (or parts of them) called antigens, that stimulates the body's immune system to create antibodies and memory cells against a specific disease.
