Are the leaves of English Ivy simple or complex? I'm not sure how a vine would be classified in this aspect.
English Ivy?
By ' English Ivy ' I hope you are talking about = Hedera helix =

The leaves are alternate, 50-100 long, with a 15-20 cm long petiole; they are of two types, with palmately five-lobed juvenile leaves on creeping and climbing stems(They are lobed but still simple), and unlobed cordate ( Heart shaped ) adult leaves on fertile flowering stems exposed to full sun, usually high in the crowns of trees or the top of rock faces.
The leaves are SIMPLE ( the opposite of it is COMPOUND leaves and not 'Complex " )
There is no relation between the leaves and vine classification.
Fern Leaves Are Compound . Pinnately Compound to be very precise .

This DIAGRAM depicts and names the components of a fern frond.
Fronds are the equivalent of leaves (generally compound leaves) in an angiosperm, but since they often carry the fertile structures of the plant on the underside, the distinct term frond is used. No other plants use leaves in this way.

Reply:I just woke my wife up and asked her. I only dared ask each question once. I didn't catch the answer to whether the ivy is simple or complex because she was still 9/10ths asleep but she said that fern leaves are complex. She also said (quite adamantly I might add) that the two are completely different. Then she rolled over and went back to sleep so I hope that answers your question. She is a 4'th year PhD student in plant biology so I'd bank on the correctness. She knows her leaves.
