It is essential for growth, repair, and reproduction.
What are the main components of the reproductive system?
Sperm, Egg, Uterus, Testes, Ovaries
What do cells need to survive?
A constant supply of nutrients, oxygen, and water, and they must remove waste products.

Kidneys, Bladder
What are mitochondria often referred to as?
The 'powerhouses' of the cell
What is the role of traditional burning practices in Indigenous Australian fire management?
They help maintain biodiversity and reduce the risk of large-scale wildfires.
What is the role of the cell wall in plant cells?
It provides support and protection.
What are the main components of the circulatory system?
Heart, Arteries, Veins, Capillaries, Red blood cells
Choose a disease and describe its treatment.
Diabetes has evolved from insulin extraction from animals to synthetic insulin production.
What is excretion?
Excretion is the process of removing waste from the body.
Compare unicellular and multicellular organisms.
Unicellular organisms are made up of a single cell, while multicellular organisms are made up of many cells.
How do the circulatory and respiratory systems work together?
The circulatory system transports oxygen and nutrients to cells, while the respiratory system takes in oxygen and removes carbon dioxide.
What criteria do different groups consider when deciding on medical technology?
Factors like cost, effectiveness, safety, and accessibility.
What is the jelly-like substance that fills cells called?
Cytoplasm
Why do cells need to divide?
To allow for growth, repair of damaged tissues, and reproduction.
Give examples of beneficial and harmful effects of microorganisms.
Beneficial microorganisms include bacteria that aid in digestion, while harmful microorganisms can cause diseases.
What are the effects of diabetes on the body?
Diabetes can affect multiple systems, including the circulatory, nervous, and excretory systems.
Compare photosynthesis and cellular respiration.
Photosynthesis produces energy while cellular respiration releases it.
What is the reproductive system?
The reproductive system includes all of the organs and structures involved in reproduction.
How can you observe cells and identify their structures?
By using a microscope or Bioviewer
Write the word equation for cellular respiration.
Glucose + Oxygen → Carbon dioxide + Water + Energy (ATP)
What is the hierarchy of structure in multicellular organisms?
Cell, Tissue, Organ, System, Organism
What is a disease?
A disease is an abnormal condition that affects the structure or function of an organism.
What did Priestly's experiments demonstrate?
Plants produce oxygen and consume carbon dioxide, essential for animal life.
What are the roles of plant organs?
Flowers: Reproduction, Roots: Anchoring and absorbing water/nutrients, Stems: Support and transport, Leaves: Photosynthesis
What are the basic units of life that all living organisms are composed of?
Cells
What organelles are responsible for photosynthesis in plant cells?
Chloroplasts
What are the main components of the respiratory system?
Lungs, Trachea, Diaphragm
What is photosynthesis?
The process by which plants use sunlight, water, and carbon dioxide to produce glucose and oxygen.
What is the respiratory system?
Our respiratory system is what allows us to breathe.
What are alveoli?
Alveoli are small air sacs, where fast gas exchange occurs.
What are the main components of the skeletal muscular system?
Bones, Ligaments, Tendons, Muscles
What type of research has been crucial for diabetes treatment?
Research on insulin, glucose metabolism, and genetic factors.
Write the word equation for photosynthesis.
Carbon dioxide + Water + Sunlight → Glucose + Oxygen
What advances in scientific knowledge have improved agricultural practices?
Genetics, Plant breeding, Soil science
What is gas exchange?
Gas exchange is the exchange of oxygen and carbon dioxide.
What is sexual reproduction?
Sexual reproduction involves joining the genetic material from two parents to produce offspring.
What is the function of the cell membrane?
It surrounds the cell and controls the movement of substances in and out.
How does cellular respiration meet the needs of cells?
It provides cells with the energy they need to carry out their functions.
What are the main components of the digestive system?
Teeth, Salivary glands, Esophagus, Stomach, Small intestine, Large intestine
What role does scientific knowledge play in diabetes treatment?
Advances in genetics, biochemistry, and pharmacology have contributed to diabetes treatment.
What is the digestive system?
The digestive system is made up of a number of different organs, including the mouth, oesophagus, stomach, small intestine, large intestine, rectum, and anus.
What are blood vessels?
Blood vessels are the tubes that run all over your body, carrying blood inside them.
What are muscles?
Muscles are elastic tissue that contract and relax to produce movement.
Describe a technology used in diabetes management.
Insulin pumps, continuous glucose monitoring systems, and artificial pancreases have improved diabetes management.
How does photosynthesis meet the needs of plant cells?
It provides plants with energy and the building blocks for growth.
What is digestion?
Digestion is the process of breaking down food into smaller pieces.
What is the heart?
The heart is an organ in the circulatory system that pumps blood.
What is meiosis?
Meiosis is a type of cell division that produces four new 'daughter' cells that are haploid.
What do bones do?
Bones provide a frame to support our body, protect important organs, and work with muscles to help us move.
What is the role of scientists in studying ecosystems?
Scientists study ecosystems to understand the role of fire and develop sustainable land management practices.
What is the excretory system?
The excretory system is an organ system that is responsible for removing wastes from our body.
What is absorption?
Absorption is the movement of nutrients from the digestive system into the bloodstream.
What is asexual reproduction?
Asexual reproduction involves the genetic material from only one parent, producing genetically identical offspring.
What are physical and chemical digestion?
Physical digestion is the process of physically breaking down food into smaller pieces. Chemical digestion is the process of chemically breaking down food into smaller pieces using digestive enzymes.
What does the liver do?
The liver is responsible for the chemical breakdown of substances in our bloodstream.
What is the male reproductive system?
The male reproductive system functions to provide and deliver the male gamete (sperm) for fertilisation.
What is blood?
Blood flows through our circulatory system. It’s a mixture of lots of components—both liquid and solids.
What is the female reproductive system?
The female reproductive system is designed to accommodate fertilisation and reproduction.
