Which is one of the differences between non-flowering seed plants and flowering seed plants?
A) Presence of stomata in the roots.
B) Amount of sugar stored in the roots.
C) Presence of tracheids and vessels.
D) Structure of parenchyma cells.
100% certain! The answer is in your Biology Textbook !!
Do you have a guess as to what the answer might be? Can you eliminate some right off the bat?
Guest 1 is not entirely wrong. If the question comes from a textbook then the answer is indirectly in your textbook. Think about the properties of non-flowering seed plants.
I just read this from Google
"Tracheids are present in all vascular plants whereas vessels are confined to angiosperms. Tracheids are thin whereas vessel elements are wide. Tracheids have a much higher surface-to-volume ratio as compared to vessel elements. Vessels are broader than tracheids with which they are associated.M....
If you do not know what an angiosperm is then google it.
