Pyrenoids contain protein besides starch.
Sexual reproduction may be isogamous, oogamous and anisogamous in green and brown algae.
Some of the members of algae also occur in association with fungi (lichen) and animals (eg, on sloth bear).
The leaves in pteridophytes are well adapted to withstand extremes of temperature, humidity and wind.
