Specialised cells and levels of organisation

By the end you’ll be able to

• Explain how specialised animal and plant cells are adapted to their functions, using named examples such as sperm cells, nerve cells, muscle cells, root hair cells, xylem cells and phloem cells.
• Relate the subcellular structures present in specialised cells to the jobs those cells carry out.
• Describe the hierarchical organisation of multicellular organisms as cells, tissues, organs, organ systems and organisms.
