(a) dicliny
(b) monocliny
(c) cleistogamy
(d) self sterily
(e) protandry
(f) dichogamy

• A. a, d, e and f
• B. b, d, e and f
• C. a, c, d and f
• D. a, b, c and d

Answer 1

The correct option is A a, d, e and f

C. a, c, d and f

EXPLANATION: In diclinous plants cross-pollination can be found. These plants hold unisexual flowers. Pollination of cleistogamous flowers is called cleistogamy. The presence of both flower types allows mixed breeding system species to the process of cross-pollination. Self-sterile, this term is used for describing plants, which are not able to set self-seed in the time of growing in isolation or when they are self-pollinated. The cross-pollination process is used to transfer pollen from the anther to the stigma of a flower on a different plant, that is called dichogamy.
