Q9.The condition where filaments and anthers are fused throughout entire length is
Solution
(a)In synandrous condition of androecium, the anthers and their filaments are fused and form a group. In gynandrous condition, the stamens are fused with gynoecium. In protandrous condition, male flowers become mature before female in a bisexual flower. In syngenesious condition, anthers become fused but filaments remain free.
