Select the incorrect statement for the given figure, choose the correct option:
Options
- AThis plant has small specialised roots called coralloid roots are associated with N 2 - fixing cyanobacteria.
- BThe stems are unbranched.
- CIn this plant the pinnate leaves persist for a few months.
- DIn this plant male cones and megasporophylls are borne on different trees.
Correct answer
C. In this plant the pinnate leaves persist for a few months.
Step-by-step solution
Roots in some genera have fungal association in the form of mycorrhiza (Pinus), while in some others (Cycas) small specialised roots called coralloid roots are associated with N 2 - fixing cyanobacteria. The stems are unbranched (Cycas) or branched (Pinus, Cedrus). The leaves may be simple or compound. In Cycas the pinnate leaves persist for a few years. The male or female cones or strobili may be borne on the same tree (Pinus). However, in cycas male cones and megasporophylls are borne on different trees.
