Read the following statements and select the correct option:- A. Gymnosperm does not show xerophytic character. B. In Cycas , coralloid roots are associated with fungi. C. All gymnosperms are heterosporous. D. In conifers, needle-like leaves reduce the surface area. How many above statements are correct?
Options
- AA, B and C
- BB, C and D
- CC and D
- DA and D
Correct answer
C. C and D
Step-by-step solution
Gymnosperm grows in the temperate snow-covered area which is physiologically dry thus they show xerophytic adaptations. In Cycas, coralloid roots are associated with blue-green algae. All gymnosperms are heterosporous as they produce two types of spores, smaller microspores and large megaspores. In conifers, leaves are modified into pointed needles to reduce surface area.
