My creation of the merostrich (mer-ostrich) or hydrostrich (hydro-ostrich; water-ostrich) helped myself and my classmates remember the details of phospholipids for out Biology AS Level.
A merostrich lives on the ocean, its legs sticking straight into the air and its head in the water (as a nod to the silly notion that ostriches put their head in the sand).
Hence the merostrich's head is hydrophilic ('water loving' with 'philic' from 'philia' meaning love) and its legs are hydrophobic ('water phobic' as in having a phobia, being intensely afraid of something, NOT hating it).
A phospholipid has a hydrophilic phospate head and some hydrophobic fatty acid tails.

AS Levels
Five days until my first exam: Biology. Yuck.
At least this year I only have seven. Only if every subject had coursework like English... which still haven't been given back to us. It's been four (or five) weeks since we gave in our final drafts. I respect that teachers have more than just my year group to worry about, but surely coursework should be prioritised?!?
Waiting to do my GCSEs was bad enough, but this is INTENSE! Each subject has twice as much information in it as a two-year GCSE. It is too much to remember: apparently, instead of taking modules in January, it's better to remember more for longer. Yeh... sensible, not really.
At least when we start A2 after May half term I can drop a subject. That'll be tension gone.
