Some cells formed in the cambium of a young tree develop into xylem vessels. Other cells formed from the same cambium develop into phloem sieve tubes. Before differentiation, the cells formed from the cambium contain the same genes.
Explain how the two cell types develop different structures and why having both cell types benefits the tree.
194 exam-style questions on OCR GCSE Biology 2.1 Supplying the cell, covering 2.1.1 Transport across cell membranes, 2.1.2 Mitosis and the cell cycle, 2.1.3 Importance of cell differentiation, and 2.1.4 Stem cells. Each one has a worked solution and a mark scheme showing where the marks go.
