The largest organ in the human body.
What is the skin?
This is the largest animal ever to have lived on Earth.
What is the Blue Whale?
This type of microorganism can cause diseases such as food poisoning.
What is bacteria?
This process allows plants to make glucose using light energy.
What is photosynthesis?
This molecule carries the instructions for making proteins.
What is DNA?

During exercise, muscles may respire anaerobically and produce this substance.
What is lactic acid?

This fish is the largest fish species in the world, despite being a filter feeder that eats tiny organisms.
What is the whale shark?
This structure allows many bacteria to move.
What is a flagellum? 
This gas enters leaves through stomata after photosynthesis.
What is oxygen?
This animal can survive extreme conditions, including radiation, freezing temperatures and even the vacuum of space.
What is a tardigrade (water bear)?
This molecule found in red blood cells, that transports oxygen around the body.
What is haemoglobin?
This process causes coral to lose its colour when stressed by increased ocean temperatures.

What is coral bleaching?
This type of pathogen is not considered living because it cannot reproduce independently.
What is a virus?

What are plasmids?
This tree is the tallest living organism on Earth, with some individuals growing over 100 metres tall.
What is the coast redwood?

This organelle originated from ancient bacteria that were engulfed by early eukaryotic cells according to the endosymbiotic theory.
