Biology — Structure and Function

Cells and cell structures

Understand that all organisms are made of cells and microorganisms are typically single celled. · Identify and describe the functions of cell structures (limited to cell membrane, cytoplasm, nucleus, cell wall, chloroplast, mitochondria and sap vacuole). · Describe the similarities and differences between the structures of plant and animal cells.

Specialised cells and levels of organisation

Explain how the structures of some specialised cells are related to their functions (including red blood cells, neurones, ciliated cells, root hair cells and palisade cells). · Understand that cells can be grouped together to form tissues, organs and organ systems.
