Biology: Intermediate
Go past the outline: classify, dissect the structures, and run the body's own numbers.
What you'll learn
- ✦Classify a plant or animal into its kingdom and phylum/class from its defining features
- ✦Describe the external structure of a flowering plant and explain how a stem grows thicker with age
- ✦Describe how tissues are organised in an animal body, using an earthworm as the example
- ✦Describe a cell's organelles in structural detail and name the four biomolecule types by their structure and role
- ✦Explain the stages of mitosis and meiosis and say why the body needs both
- ✦Explain how water and minerals move up a plant, how a leaf makes and uses food, and how a hormone controls growth
- ✦Explain digestion and absorption, breathing and gas exchange, and blood circulation in the human body
- ✦Explain how the kidney removes waste, how bones and muscles produce movement, and how neurons and hormones control the body
