,Things carried in blood plasma
• Amino acids
• Water
• Carbon dioxide
• Lactic acid
• Glucose
,What’s in the phloem?
• The products of photosynthesis
, 4.1 Red blood cells
• They are biconcave disks which gives them an increased SA to V ratio
for diffusion
• The are packed with a red pigment called haemoglobin that binds to
oxygen
• They have no nucleus which creates more space for haemoglobin
