Size, light and nutrients

1. Constraints, optimization, costs

dealt with each individually

morphology

 

2. Size and. light

3. Size and nutrients

cell surface area vs. cell content

4. Light and nutrients

N limitation decreases

• chl
• PBP

Fe limitation decreases:

• Chla synthesis
• e transport
• efficiency

 

5. Size, composition and overall growth rate

at constant conditions
