What is a cell? A cell is the smallest unit of life.
What is a unicellular organism? A unicellular organism is an organism that is made up of just one cell.
Give an example of a unicellular organism. Amoeba and Euglena are unicellular organisms.
Can you name parts of amoeba? Amoeba has a nucleus, contractile vacuole, cell membrane, food vacuoles and pseudopods.
Name parts of Euglena. Euglena has a flagellum, nucleus, chloroplasts, a contractile vacuole and an eye spot.
Name some differences between Amoeba and Euglena. Amoeba has pseudopods and Euglena has a flagellum and chloroplasts.
What is a multicellular organism? This is an organism made of many types of cell.
What advantages are there to being multicellular? Multicellular organisms can be bigger and more complex.
How are cells organised in the body. Cells are organised into tissues which are organised into organs, which then belong to organ systems. Organ systems are then organised into an organism.

What are drugs? Drugs are substances that affect the way the body works.
What does a nucleus do? A nucleus controls the cell's activities.
What does the immune system do? The immune system protects the body against infections.
What does the vacuole do in a plant cell? A vacuole contains liquid to store substances in and it helps keep the cell rigid.
What is the function of the cell wall? The cell wall helps keep the cell rigid.
What would happen to an organ if the blood supply to it was cut off? An organ without a blood supply would not work because an organ needs oxygen to work.
