Question
Gymnosperms differ from both extinct and extant (living) ferns becausethey:a) Are woody.b) Have macrophylls.c) Have pollen.d) Have spores
Solution
Gymnosperms differ from both extinct and extant (living) ferns because they:
a) Are woody: This is not a distinguishing feature. Both gymnosperms and some ferns can be woody.
b) Have macrophylls: This is not a distinguishing feature. Both gymnosperms and ferns can have macrophylls, which are leaves with a highly branched vascular system.
c) Have pollen: This is a distinguishing feature. Gymnosperms produce pollen, which is a fine to coarse powdery substance comprising pollen grains, which are male microgametophytes of seed plants. Ferns, on the other hand, reproduce via spores and do not produce pollen.
d) Have spores: This is not a distinguishing feature. Both gymnosperms and ferns produce spores. However, in gymnosperms, the spores are not the primary means of reproduction, as they are in ferns. Instead, gymnosperms primarily reproduce via seeds.
So, the main difference between gymnosperms and both extinct and extant ferns is that gymnosperms produce pollen.
