34. How is cell structure related to cell function? 1) Red Blood Cell Increased surface area to volume ratio of the cell. Hence, increased transport of oxygen. Circular biconcave shape Carry more haemoglobin which leads to increased transport of oxygen. No nucleus Haemoglobin transports oxygen from the lungs to all parts of the body. Contains haemoglobin Adaptation to Function Cell Structure
35. How is cell structure related to cell function? 2) Xylem Vessel Lignin strengthens the walls and prevents the xylem vessels from collapsing. Lignified walls Enables water to move easily through the lumen. Long hollow tubes (no protoplasm) Adaptation to Function Cell Structure
36. How is cell structure related to cell function? 3) Root Hair Cell Specialised Plant and Animal Cells: http://lgfl.skoool.co.uk/keystage3.aspx?id=63 Increased surface area to volume ratio of the cell which leads to increased absorption of water and mineral salts from the soil. Long and narrow Adaptation to Function Cell Structure
