    Increase size = decrease SA: Volume * Ratio decreases = exchange decreases * Limits cell size for efficiency * Rate of heat/waste production + nutrient consumption = function of volume * Exchange rate = function of SA 2.1.7 – Multicellular organisms show emergent properties * Whole is greater than the sum of its parts 2.1.8 * Nucleus – DNA – chromosomes – genes * Differentiation occurs when genes are “switched on” = determines development * Differences

    can make copies of themselves. A cell is also a metabolic compartment where many different chemical reaction occur. There are two types of cells‚ eukaryotic and prokaryotic. Prokaryotic cells are usually unicellular‚ while eukaryotic cells can either exist as a single celled organism or be found in multicellular organisms. The unicellular and multicellular organisms are linked to cell size and surface area to volume ratio. The experiment for cell size and diffusion was set to see how and how much water
