A) Orthotropous and unitegmic
B) Orthotropous and bitegmic
C) Anatropous and unitegmic
D) None of these

Answer 1

Answer:

The correct answer is B) 'Orthotropous' and 'bitegmic'.  

Explanation:

Cycads ovule is 'Orthotropous and bitegmic.'

Cycads plants are dioecious that belong to the family Cycadaceae forming 'seed cones' on female plant and pollen cones called strobilus on the male plants.

The cycads plants have megasporophylls, but these megasporophylls are not gathered around cones. Cycads plant takes 'several years' to grow.

After 10 years of only vegetation growth, sexual reproduction takes place. The cycads plant pollinates mainly by wind pollination.
