I have a homework assignment, it to make a photosynthesis acrostic but I was not there for the notes so I have no idea what I am doing. Can anyone help me with ideas

first, google acrostics - get some examples

Then make a list of terms relating to photosynthesis, and use them to supply the letters in the acrostic.

Technically, the acrostic should be a quotation, and the first letters of the clues will spell out the author's name.
